【摘要】 征集山西和陕西具有代表性的11个野生大豆种群,在山西中部环境条件下对与进化相关的形态性状进行表现型分析。结果表明:质量性状形态相对单一;种群内个体间的数量性状值相差很大,种群间数量性状的平均差异大小有一定的地理分布性,但各性状差异表现不尽相同。利用综合变异系数,筛选出汾阳和沁源2个变异大的野生种群。综合变异系数分别为62.67%和54.33%,闻喜种群变异最小为13.33%,其它种群分布在21.33%~30.67%之间。更多还原

【Abstract】 Eleven natural populations of wild soybean were collected in Shanxi and Shaanxi Province,and their morphological traits with evolution were investigated in this study.The result showed that the polymorphism of the qualitative traits were simple;the variation of the quantitative traits was great within the populations and presented a region-dependent distribution although some traits were different in distribution patterns.Two wild populations with great variation,Fenyang and Qinyuan,were screened out by using comprehensive coefficient of variability.And the comprehensive variability coefficient of them were 62.67% and 54.33%,respectively.The Wenxi population had the lowest variability coefficient(13.33%),and that of other species distributed in 21.33%～30.67%.更多还原
