摘要: 对265份田埂豆地方品种的9个农艺性状进行遗传变异。相关及通径分析,统计结果表明:福建省田埂豆地方品种各性状均有较大的遗传变异和选择潜力,尤以分枝数、单株荚数、单株粒数和单株粒重的变异最大;茎粗的遗传率最高,结荚高度、分枝数、株高其次。各性状对产量的遗传相关系数的大小顺序为单株粒数>单株荚数>分枝数>主茎节数>株高>茎粗>百粒重。单株粒数对单株粒重的直接作用最大,株高对单株粒重的直接作用最小。Abstract: correlation and path-coefficient analysis for agronomic characteristics of 265 balk sOybean varieties of the land race from Fujian shows that all thes traits possess a great genetic variability and selection potential.Especiatly,the numbers of branches per plant,pods per plant,seeds per plant and seed weight per plant have the greatest GCV,diameter of stem has the greatest heritabili ty,secondly are podding height,braches and plant heright Seed number per plant has the greatest genetic correlation to the yields,followed by the numbers of peds per plant,branches per plant,nodes of main stem,plant heright,diameter of stem and 100-seed weight.Seed number per plant has the greatest direct effect to seed weight per plant,plant height has the least direct effect to seed weight per plant.
