【摘要】 为发掘具有优异农艺性状与品质性状的野生大豆资源,对240份黑龙江省野生大豆资源进行农艺和品质性状的遗传多样性分析。结果表明:黑龙江省野生大豆资源中主要是紫花、黑色种皮、卵圆和批针叶形、有泥膜为主;产量性状和生长性状的变异系数平均为51.55%,多样性指数平均为1.75;品质性状的变异系数平均为17%,多样性指数平均为1.94;聚类分析将试验材料分为2类,聚类分析将晚熟、单株产量高和异黄酮含量高的材料聚为一类,将叶形细长、蛋白含量高的材料聚为一类,第Ⅰ类材料主要来自黑龙江省东部和中南部地区,第Ⅱ类材料主要来自黑龙江省西部和北部地区。更多还原

【Abstract】 In order to excavated excellent wild soybean resources,240 wild soybean resources were taken as material to analyze the diversity based on agronomic and quality traits in Heilongjiang province. The results showed that,wild soybean resources in Heilongjiang province was mainly purple,black seed,oval and needle leaves and present bloom. The average variation coefficient and diversity index of yield and growth traits were 51. 55% and 1. 75,respectively. The average variation coefficient and diversity index of quality traits were 17% and 1. 94,respectively. The materials were divided into 2 groups by cluster analysis. The late maturing,high yield and high isoflavone content materials were classified into groupⅠ. The slender leaf,high protein content of materials were classified into groupⅡ. Materials of groupⅠ mainly came from the East and the South area of Heilongjiang province. Materials of groupⅡ mainly came from the North and West area of Heilongjiang province.更多还原
