Morphological Characteristics of Flower Organ and Cytological Observation of Microspore in Different Development Stage in Radish（Raphanus Sativus L.）
Li Dan;Li Xixiang;Shen Di
The developmental stage of microspores was observed by two different methods： acetic magenta staining and DAPI staining.It was found that the nucleolus in microspore display more clearly by DAPI staining than acetic magenta staining.The relationship between microspore developmental stage and morphological characteristics of flower buds and anthers was studied by both of cytological and morphological methods on four different radish genotypes.There were significant differences in longitudinal diameter and transverse diameter of flower buds，the ratio between longitudinal diameter and transverse diameter of flower buds，anther length，anther width，petal length，the ratio of petal length and anther length，during the developmental stages of the microspore in all four different radish genotypes.At the late-single nucleus stage，significant difference existed in all the above-mentioned index of different varieties.It indicated that the longitudinal diameter of buds，the ratio of the longitudinal diameter and the transverse diameter of flower buds，petal length and the ratio of the petal length and the anther length were suitable for the determination of sampling time for microspore culture.The appropriate longitudinal diameter of buds ranged 2.991-3.510 mm and the ratio of the longitudinal diameter and the transverse diameter of flower bud ranged 1.412-1.480，the petal length ranged 1.889-2.561 mm，the ratio between petal length and anther length ranged 0.923-1.057.In addition，it is necessary that the anthers should be covered by the sepal，the length of sepal was equal or close to the anther lenghth，and the flower bud was full，the anther showed from light yellow to yellow.

The Effect of DNA Demethylation on Vernalization in Broccoli（Brassica oleracea L.var.italica Plenck）
Yu Xihong;Li Dan;Jiang Xinmei
Abstract Taking two varieties of broccoli‘Qingfeng 103’and‘Luxiu’as materials，we adopted different 5azaC treatments on them at young seedling stage，tested the influence of DNA demethylation on vernalization and C/N during vernalization in broccoli.The results showed that the 5-azaC spraying treatment could promote vernalization and shorten flower-bud differentiation stage，and its ratio of total sugar to total nitrogen，soluble sugar to soluble protein，sucrose to soluble protein were higher than the root fertilizing treatment，CK-W and CK-T.

Impacts of Plantlet Age and Cultivation Substrates on Domestication Survival Rate of Transgenic Plantlets of Cucumis sativus L.
Miao Minmin;Xu Ran;Zheng Lijuan;et al.
Taking transgenic plantlets of Cucumis sativus L.as material，we studied the impacts of plantlet age，cultivation substrats and sucrose concentration in rooting media on root development and domestication survival rate of Cucumis sativus L.transgenic in vitro culture plantlets.The results showed that the best root development and the highest survival rate can be obtained when the plantlets were rooted in 1/2 MS media with 6 % sucrose for 28 days and transformed to the same media with 3 % sucrose for 7 days，then transplanted in the cultivation substrates of peat ∶perlite ∶river sand=1 V ∶1 V ∶1 V at 6-true leaf stage.

Analysis of Genetic Diversity in Luffa via Morphological and RAPD Markers
Xia Junhui;Xiang Changping
In our study，the genetic diversity in 26 luffa accessions were assessed via morphological and RAPD markers，and the genetic relationship among these accessions was revealed by hierarchical cluster analysis.Coefficient of variation based morphological traits ranged from 5.27 % to 107.00 % with the average of 32.75 %.A total of 200 10-mer random primers were used in this study.16 screened primers produced 145 extending and repeatable RAPD bands，of which 125 bands（86.21 %）were polymorphic across 26 luffa accessions.The average Shannon’s information index of RAPD loci was 0.325.The 26 luffa germplasms were clustered into 2 groups based on the morphological markers and RAPD markers by the method of hierarchical cluster analysis respectively.But the clustering results of RAPD markers are not identical with the morphologic classification.

Identification Technology for Resistance to Target Leaf Spot of Cucumber and Identification for Variety Resistance
Wang Huizhe;Li Shuju;Guan Wei
Pycnoconidia solution of 30 000-40 000 per mL was used as identification method for resistance to target leaf spot of cucumber.The solution was sprayed on to the seedlings with 1 true leaf and kept in moisture for 24 hours.Inoculation results showed that 3 accessions were high resistant and 2 accessions were resistant to target leaf spot.‘Jinyou No.3’and‘Jinyou No.38’were high resistant varieties to target leaf spot.

Breeding and Utilization of Male Sterile Line 117A in Radish
Hu Tianhua;Mao Weihai;Bao Chonglai;et al.
The original male sterile source from the radish CMS‘Zhe 3A’was transferred to radish inbred line 117.An excellent new male sterile line 117A with good economic traits and stable sterility was obtained by crossing and backcrossing.The rates of male sterile plants of 117A was 100 %，and the traits of flowering and seeding were excellent.The cross combinations using 117A had showed strong heterosis.
