摘要： 对引进的19份毛豆品种的10个主要农艺性状进行相关性分析。研究表明，1)农艺性状变异系数大小依次为主茎分枝数、百粒重、单株荚数、底荚高、单株粒数、株高、单株产量、主茎节数、茎粗、生育期。2)单株产量与百粒重呈极度正相关，与底荚高、主茎分枝数、茎粗、单株粒数呈正相关，与株高、主茎节数、单株荚数呈负相关。因此要增加单株产量，首先要考虑选择百粒重大的品种，其次是选择茎杆粗壮，主茎分枝数及单株粒数较多的品种。

Abstract: The 10 agronomic traits in 19 varieties of soybean have studied. The results showed as follows: 1) The ordinal genetic coefficient of variation were the number of branches, 100-seeds weight, Pods on stem, the height of lowest legume, seeds per plant, plant height, the seed weight per plant, node number, diameter of stem and the bearing term.2) There were significantly correlations between seed weight per plant and 100-seeds weight .The seed weight per plant is positively correlated with the height of lowest legume, number of branches, diameter of stem and seeds per plant; The seed weight per plant is negatively correlated with Plant height, Node number and Pods on stem.
