摘  要:组织实施大豆品种(系)在桂北地区适应性观察和鉴定性试验,为大豆数量性状选择提供参考。应用灰色关联度对多点鉴定试验的30个大豆品种(系)的12个农艺性状与单株产量进行分析。结果表明,大豆单株产量与相关农艺性状的关联度大小依序为有效分枝(0.780 1)、百粒重(0.777 1)、主茎节数(0.768 1)、有效荚数和单株粒数相同(0.767 3)、每荚粒数(0.766 4)、底荚高度(0.764 1)、株高(0.757 6)、虫蚀率(0.740 4)、生育期(0.731 7)、褐斑率(0.728 3)、紫斑率(0.722 7)。由此表明,在桂北生态区进行大豆品种(系)选择和推广时应优先考虑有效分枝、百粒重、主茎节数、有效荚数和单株粒数。In order to provide reference for selection of quantitative characters of soybean, soybean varieties (lines) in the observation and identification of adaptability test in northern Guangxi were carried on in this paper. 12 agronomic traits and yield of 30 soybean varieties (lines)were analyzed by grey relational analysis. The results showed that the correlation degree of yield per plant of soybean and related agronomic traits appeared in the order of: effective branches (0.780 1 ), 100 grain weight (0.777 1 ), node number (0.768 1 ),the same of pod number and seed number per plant (0.767 3) ,seeds per pod(0.766 4) ,the height of the bottom pod(0.764 1 ) ,plant height (0.757 6) ,insect erosion rate(0.740 4) ,Growth period(0.731 7), brown spot rate (0.728 3 ), purple spot rate (0.722 7 ). Thus, effective branches, 100 grain weight, stem node number, pod number and seed number per plant for soybean variety selection are priority selected index in North Guangxi agriculture ecological region.
