    In order to explore the possibility of predicting pepper yield heterosis based on SNP marker
    molecular genetic distance，and realizing early prediction of pepper heterosis and screening strong heterosis
    combinations，this paper took 12 pepper inbred lines as parents，and compared the relationship between
    molecular genetic distance and yield heterosis based on genome-wide SNP markers by 2 methods of individual
    analysis and grouping analysis．Eight inbred lines from 12 inbred lines were chosen at random in individual
    analysis．It was found that there were irregular changes between genetic distance and yield heterosis．62.5%
    of the inbred lines were accorded with the rule of the farther the genetic distance was，the stronger the heterosis
    was．In grouping analysis，it was found that along with the increase of genetic distance，the heterosis value
    showed an upward trend on the whole，indicating the bigger the genetic distance between pepper parents，the
    greater possibility of obtaining high yield and strong heterosis combination．The genetic distance based on SNP
    markers could be used to predict the heterosis of their offspring．

    This paper studied the characteristics of albino seed pod in cabbage alb1 by paraffin section
    technique．The results showed that the cells were abnormal in morphology development，cell walls were
    deformed and cell boundaries were not obvious．The results of genetic analysis showed that the separation
    ratio of green pod to albino pod was 3∶1，indicating that this albino seed pod trait is controlled by a single
    recessive gene．The differential expression in albino pod mutant alb1 and green pod Chinese kale TO1000 were
    analyzed by high-throughput RNA-sequencing．A total of 4 530 genes were differentially expressed between
    alb1 and TO1000．Among them，2 569 were up-regulated genes and 1 961 were down-regulated genes．
    These differentially expressed genes were mainly involved in ribosome，plant hormone signal transduction
    and fatty acid elongation．Plant hormone signal transduction was especially important for construction of cell
    morphology，which might be the important reason for cell development malformation and emergence of albino
    seed pod．

    Four kinds of biocontrol bacteria NSY4，NSY19，NSY50，DSN012 with measurable
    restraining effect on cucumber Fusarium wilt were screened from 15 biocontrol bacterias by slab opposing
    method．Taking cucumber（ Cucumis sativus L. cv Jinyan No. 4） as test material，this paper studied the effects
    of 4 biocontrol bacteria substrates on cucumber growth and Fusarium wilt control．The results showed that
    biocontrol bacteria substrate NSY4 could significantly increase the plant height of cucumber seedling，fresh
    weight of above ground part，fresh weight of underground part，dry weight of above ground part，and total
    root length and root volume，by 42.86%，26.09%，47.06%，58.82%，57.58% and 51.44% respectively，
    comparing with the CK-no adding of biocontrol bacteria．In addition，the enzyme activity of matrix in
    cucumber rhizosphere was significantly higher than that of the CK．Compared with the CK，the invertase，
    urease，phosphatase and catalase activity increased by 16.20%，37.60%，71.88% and 5.22%，respectively．
    The numbers of bacteria and actinomycetes in the treatment of adding biocontrol bacteria matrix were
    significantly increased．While，the numbers of fungi and Fusarium oxysporum were reduced．The control
    effect on cucumber Fusarium wilt had reached 25.00%-62.50%．Therefore，inoculating biocontrol bacteria
    matrix could promote cucumber plant growth and reduce incidence rate of cucumber Fusarium wilt．Treatment
    of adding biocontrol bacteria NSY4 to substrate could significantly promote cucumber plant growth，
    effectively alleviate the damage of Fusarium oxysporum，and had the best control effect on cucumber
    Fusarium wilt．

    In order to definite the effects of different proportion of chemical fertilizer replacing organic
    fertilizer on active organic carbon and enzyme activity in yellow loam soil in Guizhou Province under equivalent
    fertilization conditions，this paper took typical yellow loam soil samples from Guizhou Province as research
    object and studied the effects on soil total organic carbon（TOC），dissolved organic carbon（DOC），readily
    oxidized carbon（ROC），microbial biomass carbon（MBC），and soil cellulase，invertase，urease，acid
    phosphatase activity，and pepper yield by 6 treatments of mixing compound fertilizer with chemical fertilizer
    and organic fertilizer．These treatments included no fertilization（CK），100% chemical fertilizer（T1），70%
    chemical fertilizer + 30% organic fertilizer（T2），50% chemical fertilizer + 50% organic fertilizer（T3），
    30% chemical fertilizer + 70% organic fertilizer（T4），and 100% organic fertilizer（T5）．The results showed
    that replacing chemical with organic fertilizer could increase the soil TOC，DOC，ROC，and MBC contents．
    Compared with T1，the TOC，DOC，ROC and MBC contents were increased by 15.45%-55.82%，20.29%-
    91.30%，34.85%-51.21%，37.78%-71.11%，respectively．While，the organic carbon pool management index
    （CMI） was increased by 36.95%-53.78%．The soil cellulase，sucrase and urease activity all showed the
    trend of increasing first then decreasing，and soil acid phosphatase activity showed a continual boosting trend
    along with the increase of replacing proportion of organic fertilizer．Compared with the CK，fertilization could
    significantly improve pepper yield．The pepper yield was the highest in T2（50% chemical fertilizer + 50%
    organic fertilizer），reaching 25 765.63 kg·hm-2，obviously 13.90%-49.36% higher than the other fertilization
    treatments．On the whole，replacing chemical fertilizer with organic fertilizer can increase the active organic
    carbon content，soil organic carbon pool management index，microbial activity and pepper yield of yellow
    soil．From the perspective of improving soil carbon sequestration and yield-increasing effect，the application
    rate of 50% chemical fertilizer + 50% organic fertilizer is the recommended fertilization measure．

    The bitter gourd inbred lines ‘K7-359’（P1） and ‘K7-422’（P2）were taken as female and
    male parents，respectively，to produce F1 and F2 populations．Major gene plus polygene mixed inheritance
    model was used to perform genetic analysis for seed length，seed width and single seed weight of bitter gourd．
    Results showed that the inheritance of seed length and single seed weight were consistent with the polygenic
    genetic model with additive-dominant-epistasis effect（C-0 model）．The polygenic heritability were 84.91%
    and 76.55%，respectively，indicating that selection of seed length and single seed weight should be carried out
    in high generation．The inheritance of seed width was fitted to one pair of additive-dominant major gene plus
    additive-dominant-epistasis polygene model（D-0 model）．The heritabilities of main gene and polygene were
    79.30% and 3.86%，respectively，and genetic effect of major gene is mainly ascribed to the additive effect，
    indicating combination breeding strategy could be used for genetic improvement of bitter gourd seed width，and
    it was suitable to conduct selection on early generation．

    Tuber shape is one of the important agronomic characters of potato．Potato tuber shape has
    confirmed at the early stage of tuber development．In order to study the internal morphological changes of long
    and round tubers，this paper selected tubers formed in 4 different periods，including stem stalk hook period，
    apical bulging period，early tuber formation period，and tuber formation period to make paraffin sections to
    conduct histocytological observation．The result shows that the differences in cell layers of medullary tissue
    during stem stalk hook period might be the main reason leading to long or round different tuber shapes．The
    stem stalk hook period might be the key period causing differences in tuber shapes．
