Fresh maize is favored by the market because of its good edible quality and nutritional value.This article collected data on fresh maize varieties approved by the Sichuan Provincial Crop Variety Certification Committee from 2014 to 2023,systematically reviewed and analyzed their basic information and characteristics,and summarized the development trend of fresh maize varieties in Sichuan Province.The results showed that a total of 95 fresh maize varieties were approved in Sichuan Province from 2014 to 2023,and the dominant position of scientific research units in Sichuan was highlighted.The development of variety approval quantity was slow in the early stage,but it has rapidly increased since 2020,and sweet-waxy maize has gradually become the mainstream approval type.The kernel color of sweet maize is mainly yellow,and the color of waxy maize and sweet-waxy maize is mainly white.The growth period of the approved varieties was mostly 85-90 days,and the yield and quality were improved compared with the control,but there was a large room for improvement.However,there is a shortage of varieties with high resistance to major maize diseases.This paper also discussed the problems existing in the certification of fresh maize varieties,and put forward some suggestions from accelerating the cultivation of diversified varieties,strengthening the comprehensive resistance of varieties and optimizing the certification standards.
The target of tomato breeding has gradually shifted from the improvement of yield,resistance and other traits to the improvement of quality.Soluble solids(mainly including soluble sugars and organic acids)are the main factors that determine the quality of tomato,and also the main target of tomato quality breeding.In this paper,the composition of tomato soluble solids,the progress of the QTL and gene mapping related to tomato soluble solids content,and genetic improvement are reviewed,to provide theoretical guidance for the genetic improvement of tomato soluble solids.
Sulforaphane(SF)is a class of secondary metabolites with higher biological activity formed by hydrolysis of the aliphatic glucosinolate component-glucoraphanin catalyzed by myrosinases,which is mainly distributed in cruciferous vegetable crops.SF has anti-cancer,anti-oxidant,anti-inflammatory,detoxification,cardiovascular and diabetes prevention and other multiple effects,and has considerable utilization value in the development of functional foods and health care products.In recent years,researchers have carried out a series of work on the breeding and efficient production of high-content SF,and the cultivation measures that effectively use exogenous regulatory methods to mediate the synthesis of SF are commonly used strategies.In this paper,the structure,physicochemical properties and synthesis pathways of SF were reviewed,and the mechanism of mediation of SF synthesis by different regulatory modes(such as environmental factors,plant hormones,exogenous regulatory substances)was discussed.Finally,the existing problems and future research directions are proposed,aiming to provide some valuable references for the high-quality cultivation of high-content SF cruciferous vegetables cultivars.
The WIP transcription factor family belongs to the A1d subgroup of C2H2 zinc finger protein.At present,CsWIP1 is involved in sex determination in cucumber,but the function of WIP gene in cucumber growth and development is still unknown.This study identified 40 members of the WIP gene family in cucumber,melon,watermelon,wax gourd,bottle gourd,and zucchini.Using online websites to analyze the physicochemical properties of the WIP proteins in the Cucurbitaceae family,and conducting chromosomal localization,gene structure,and other analyses through bioinformatics.The analysis of the cis acting elements of cucumber WIP genes indicates that the WIP family genes have cis acting elements such as spatial expression,plant hormones,and photoresponse elements.Real time fluorescence quantitative PCR analysis of different tissues in cucumber revealed that CsaV3_1G014730 and CsaV3_4G031370 may play important roles in the shoot apex of cucumber;CsaV3_4G024150(CsWIP1),CsaV3_3G039140,CsaV3_7G031140,and CsaV3_5G023030 may be involved in the growth and development of female and male flowers,transmitting tract,and male gametes,suggesting that WIP gene may play an important role in the development of transport channel and regulation of leaf vein pattern in cucumber.
Inflorescence-branching structure determines the number and size of tomato fruit,which is an important component of tomato yield and a main objective in tomato breeding.To identify and clone the key regulatory genes involved in inflorescence branching,‘ST198'with complex inflorescence branching and‘ST211'with simple inflorescence branching were selected as parental lines to generate an F2 mapping population.Five major quantitative trait locis(QTLs)regulating inflorescence branching were identified using BSA-seq.Analysis and validation of the major QTL,qIB12.2,revealed that J2 was the key gene regulating inflorescence branching.J2 was found to exhibit an epistatic effect on another major QTL,qIB12.4.What's more,qIB12.4 was finely mapped to the 446.7 kb region,and closely linked molecular markers were developed.Our findings provide insights into the genetic regulatory network underlying tomato inflorescence development and have important application value for precise molecular breeding of tomato.
Chili peppers are vegetables rich in nutrients such as vitamin C,etc.According to their utilization,they are mainly divided into processed and fresh-eating types.To investigate the differences in fruit quality components between the two types of chili peppers at different developmental stages,this study used high-performance liquid chromatography(HPLC)technology to identify and quantify the quality components of vitamin C,capsaicin,and 17 amino acids in the fruits of the processed chili pepper‘P025'and the fresh chili pepper‘P245'during the green and red ripening fruits,and conducted statistical analysis.Our study found that the vitamin C contents of the two types of chili fruits during the green ripening period were close,with no significant difference,while during the red ripening period,the vitamin C content of the fresh type‘P245'fruit significantly increased,but the vitamin C content of the processed type chili pepper‘P025'fruit did not show significant changes.Results found that the content of capsaicin in the fresh‘P245'fruit during the green ripening period was significantly higher than that in the processed chili pepper‘P025',while in the red ripening period,the content of capsaicin in the fresh‘P245'fruit significantly decreased,only 11.98% of its green ripening period,while the content of capsaicin in the processed chili pepper‘P025'fruit did not show significant changes.Our research found that methionine and cysteine had the lowest contents among the 17 amino acids in chili peppers,and their combined proportion was significantly lower than the amino acid pattern spectrum standard,making them the first limiting amino acids for the two types of chili peppers.In addition,the proportion of valine and isoleucine were slightly lower than the amino acid pattern standard.As the fruits ripened,the contents of 17 amino acids in the fresh chili pepper‘P245'fruit showed an upward trend,and the total amino acid content in the red ripe fruit was 57.53% higher than that in the green ripe fruit.The processed chili pepper‘P025'fruit showed a downward trend in amino acid content except for cysteine,with the total amino acid content of its red ripe fruit decreasing by 41.21% compared to the green ripe fruit.These results revealed significant differences in the quality components of the processed type chili pepper‘P025' and fresh chili pepper‘P245' at different fruit developmental stages.
The metabolites in asparagus with different gender and color were determined and analyzed by extensive targeted metabolomics based on Ultra-high performance liquid chromatography-tandem mass spectrometry with‘Lulusun No. 7'as the material.The results showed that samples of GAF,GAM and WA were distinguished by PCA and OPLS-DA analysis.A total of 926 metabolites identified by detection were classified into 12 categories,among which flavonoids and phenolic acids were the most abundant,accounting for 35.6% of the total number of metabolites.Differential metabolites were screened and analyzed. It was found that contents of steroids in GAM were higher than that in GAF,and the contents of 31 out of 39 identified steroid metabolites were increased.The contents of steroidal saponins in GAM and GAF were lower than those in WA,and the number of down-regulated steroids accounted for about 84.6% of the total steroids.The contents of flavonoids and phenolic acids were higher than those in white asparagus,and the number of up-regulated accounted for about 62.4% and 45.5% of the total,respectively.Functional annotation and cluster analysis were carried out on the different metabolites in different gender and color asparagus,and 4 and 7 kinds of metabolites with larger difference multiple were found respectively.Diosgenin belonging to the steroid class was the unique differential metabolite of female and male asparagus.Coniferin,quercetin,3-phospho-D-glyceric acid,1-O-sinapyl-D-glucose and guanidinoacetate were unique differential metabolites of green and white asparagus.The results provide a theoretical basis for breeding,quality analysis and exploration of health functions in asparagus.
Drought and improper nitrogen fertilizer application are significant issues affecting the green and high-quality development of the potato industry.Using the varieties‘Favorita'and‘Zhongshu No.18',we conducted a pot experiment under rain shelters to analyze the effects of different water and nitrogen management strategies on photosynthesis,nitrogen metabolism enzymes,dry matter accumulation and distribution,yield,and water and nitrogen use efficiency in potatoes.The results show that all photosynthetic indicators,whole-plant dry matter,yield,and water and nitrogen use efficiency were significantly influenced by water,nitrogen,and their interaction.The impact of nitrogen application rate was greater on‘Zhongshu No.18'than on ‘Favorita'.Photosynthetic characteristics,yield,and water use efficiency initially increased and then decreased with increasing nitrogen application rate,while nitrogen use efficiency decreased with increasing nitrogen application rate.Except for water use efficiency,all other indicators increased with increasing water levels.Whole-plant dry matter increased with higher water and nitrogen levels,but dry matter allocation to tubers increased with higher water levels and decreased with higher nitrogen levels.Nitrate reductase(NR)and glutamine synthetase(GS)activities were significantly affected by water and nitrogen,respectively,with NR activity being higher at moderate water levels and GS activity being higher at high nitrogen levels.Dry matter accumulation,net photosynthetic rate,number of tubers,and yield per plant showed extremely significant positive correlations in both varieties.Through equation fitting,the optimal nitrogen application rates for maximum yield under low,medium,and high water levels for‘Favorita'and‘Zhongshu No.18'were determined to be 7.55,9.95,and 11.66 g per plant and 8.67,10.09,and 12.83 g per plant,respectively.These findings provide a theoretical basis for efficient nitrogen management in different irrigation zones for potato cultivation.
To screen the germplasm resources and determine the evaluation indexes and methods for low temperature fruiting tolerance,30 excellent tomato varieties at home and abroad were used as materials,and nine important traits were investigated and analysed during the flowering and fruiting period of tomato in the summer and autumn tomato crops,winter and spring tomato crops,respectively.The optimal regression equation and evaluation indexes for low temperature fruiting tolerance in tomato was established using multivariate statistical analysis.The results of correlation analysis showed that there were different degrees of correlation between different traits.Four principal components were extracted from the principal component analysis,and their cumulative contribution was 82.739%.The composite evaluation values(D)of the 30 tomato varieties ranged from 0.207 to 0.850,with QT-102 having the highest D value and QT-39 having the lowest D value.Cluster analysis classified the 30 tomato varieties into three groups:strong cold-tolerant,more cold-tolerant and cold-sensitive.Stepwise regression analysis established the optimal equation for predicting low-temperature fruiting tolerance in tomato:D = 0.026α1 - 0.095α2 + 0.049α3 + 0.101α5 + 0.246α6 + 0.167α8 + 0.147α9 + 0.042,and the screened indicators were:mass weight of a single fruit,number of ventricles,fruit shape index,number of flowers in a single inflorescence,number of fruits in a single inflorescence,deformed fruit composite index,and the average grade of deformed fruits.The D value of the validated equation is highly significant and positively correlated with the regression value,and the coefficients of the seven indicators are linearly correlated with the D value to varying degrees.The results provide a theoretical basis for the selection and breeding of tomato varieties with low temperature fruiting tolerance.
In this study,we meticulously evaluated the related agronomic characters of 47 garlic germplasm resources,screening the excellent germplasm of single clove garlic,and the bulb growth and development process of typical germplasm was observed by phenotype and cytology.The results showed that among 47 garlic germplasms,the comprehensive analysis of agronomic characters of ‘Wenjianghongqixing' is the best,and the single clove garlic rate was much higher than other germplasm,which is the best germplasm for producing single clove garlic.The correlation analysis of main yield characters and agronomic characters showed that the single clove garlic rate was positively correlated with the transverse diameter of garlic bulb,and negatively correlated with the number of leaves per plant,plant height,pseudostem height,pseudostem diameter,leaf length and leaf width,which could be used as an auxiliary index for screening excellent germplasm of single clove garlic.By observing the growth and development phenotype of underground bulb of ‘Wenjianghongqixing'it was found that the growth and development of single clove garlic was divided into dormancy,germination,seedling,scale bud differentiation and bulb expansion.In the seedling stage,the diameter,girth and weight of bulb were the smallest,and the plant grew faster after entering the scale bud differentiation stage.Anatomical observation of its bulb showed that many small scale buds were formed in the bulb disc during the scale bud differentiation stage,but only one scale bud expanded to form a single clove of garlic.The results of this study will provide material and technical support for the breeding and production of single clove garlic.
In order to clarify the pathogenicity differentiation of Verticillium dahliae in eggplant of Jilin Province and screen for disease-resistant materials.Two materials with different resistance were selected as identification hosts.The pathogenicity differentiation of 45 strains of V. dahliae isolated from Jilin Province was studied using the root-dip method,and based on this,the resistance of 43 materials to V. dahliae was evaluated.The results showed significant differences in pathogenicity among different strains,which could be divided into three types.The Ⅰ type had strong pathogenicity,with an average disease index greater than 70,accounting for 31.11% of the tested strains.The Ⅱ type had moderate pathogenicity,with an average disease index between 30-70,accounting for 62.22% of the tested strains.The Ⅲ type had weak pathogenicity,with an average disease index lower than 30,accounting for 6.67% of the tested strains.Analysis of the correlation between pathogenicity,culture characteristics,growth rate,and pathogenic type revealed a weak correlation.Among the 43 materials,2 disease-resistant materials were screened,accounting for 4.65% of the screened materials,6 materials with medium resistance,accounting for 13.95%,14 materials were tolerant,accounting for 32.56%,while 21 materials were classified as moderately susceptible or susceptible,accounting for 48.84%.These results provide important resistant germplasm for breeding eggplants resistant to Verticillium wilt.
Sclerotinina disease is a devastating fungal disease with worldwide distribution known to affect many commercial crops.In this study,vegetables with typical symptoms of Sclerotinina were collected from Hangzhou City,Zhejiang Province to obtain the pathogen by tissue isolation.The pathogenic fungus was identified based on the morphologies and molecular biological analysis,and then the pathogenicity was tested sensitivity to pydiflumetofen was determined by mycelial growth rate test.The results showed that 62 Sclerotinia,isolates were obtained from diseased leaf lettuce and stem lettuce,and combined with ITS and laccase 2 gene sequence analysis,6 isolates were classified into Sclerotinia minor,other 56 isolates were S. sclerotiorum.On PDA medium,the mycelial growth rate of S. minor was significantly lower than that of S. sclerotiorum,but the time of sclerotiorum production of S. minor was earlier,and the number of sclerotiorum of S. minor was higher.The virulence of Sclerotinia isolates on different vegetables were confirmed,the isolates caused the typical watery and brown lesions,and form white mycelia and sclerotiorum on infected tissues at the later stage.Sclerotiorum in Asteraceae vegetables caused by S. minor was first reported in China,and comparing the lesion diameter caused by S. minor and S. sclerotiorum,the greater virulence of S. sclerotiorum was observed on all tested hosts.Pydiflumetofen sensitivity of Sclerotinia isolates was determined by the 50% effective concentration value,the results showed that 83.9% of the assayed isolates having an EC50 of less than 0.01 μg · mL-1.Our results suggested that pydiflumetofen and its mixtures could be selected for controlling Sclerotinina on Asteraceae vegetables.
To explore a high-yield and high-quality fertilization scheme involving multiple stages of biological control for yam stem base rot disease,Taigu Chinese yams from Shanxi Province were used as experimental materials.A single application of chemical fertilizer served as the blank control.The effects of different dosages of bio-organic fertilizer combined with chemical fertilizers,as well as root dipping and root drenching with liquid microbial agents,on Chinese yam emergence rate,growth indicators,stem base rot disease index,yield,quality,economic benefits,and soil microbial richness were studied.The results showed that the emergence rate in the T2 treatment increased by 0.26 percentage points compared to the control(CK).The contents of Chinese yam polysaccharides,adhesiveness,and protein increased by 0.24 percentage points,14.81%,and 2.39 percentage points over CK,respectively.The disease index of stem base rot was the lowest in T2,with a control efficacy of 46.42%.The Chinese yam yield,the output value and the profit representing increases of 38.68%,42.53%,and 55.16% over CK,respectively.The relative abundance of Fusarium spp.,the pathogenic fungi causing stem base rot,was the lowest in the T2 group,decreasing by 3.98 percentage points compared to CK.Therefore,considering multiple factors,soaking seed yams in liquid microbial agents before transplanting,applying compound fertilizer and 30 000 kg · hm-2 of bio-organic fertilizer as base fertilizer,and alternately applying compound fertilizer and liquid microbial agents during the topdressing period constitute an effective high-yield and high-quality fertilization scheme for controlling yam stem base rot disease.
Ginger bacterial wilt is caused by Ralstonia solanacearum,which is an important soil-borne disease in the ginger production area of Guangxi.In order to clarify the genetic diversity and pathogenicity differentiation of R. solanacearum on ginger in Guangxi,this study collected strains,and conducted phylogenetic analysis based on the phylotype classification framework and egl gene sequence of the pathogen.At the same time,R. solanacearum strains were inoculated by irrigating the bacterial suspension after stabbing the stem base of ginger plant,and cluster analysis was conducted on the disease index.The results showed that all 42 strains of R. solanacearum isolated from main ginger production areas of Guangxi were identified as phylotype I,belonging to sequevar 14,16 and 30,with the former two being the main types.Through pathogenicity testing,the strains were divided into three categories:64.29% of the strains showed very strong pathogenicity,with the disease index of 83.70 to 100.00;21.43% of the strains showed strong pathogenicity,with the disease index of 62.22 to 75.56;Only 14.29% of the strains showed weak to moderate pathogenicity,with the disease index of 24.44 to 51.11.These results indicated that there is a certain degree of genetic diversity and significant pathogenicity differentiation in the population of R. solanacearum on ginger in Guangxi,providing important references for researching their pathogenic mechanisms and breeding for resistance to the disease.
