摘  要：
在玉米-大豆带状间作下,对55份大豆品种的15项农艺及产量性状进行综合分析与评价。结果表明:参试品种表型性状的变异系数为6.35%~55.76%,各性状平均遗传多样性指数达到1.984 3,说明各地的种质资源有着比较丰富的表型多样性;相关性分析表明单株粒重与茎粗、单株荚数、百粒重等9项指标呈现极显著的正相关关系,说明选择品种应着重考虑茎粗、单株荚数、百粒重等9项性状指标;通过主成分分析可以提取出5个主成分来反映这14项性状指标的信息,累计贡献率达67.29%,根据主成分得分并借助权重计算的综合得分把55份大豆品种聚类成3类,其中茎秆粗壮、单株荚数多、百粒重高、生育期适中的第一类大豆品种比较适合在黄淮海地区与玉米进行带状间作种植。

摘  要：
Fifteen agronomic and yield traits of 55 soybean varieties conducted a comprehensive analysis and evaluation under corn-soybean strip intercropping. The results showed that the coefficient of variation in phenotypic traits was between 6. 35%-55. 76% and the average Shannon'index was 1. 984 3,which illustrated that the germplasm from around had a relatively rich morphological diversity. Correlation analysis showed that the yield per plant have positively and significantly correlations with stem diameter,number of pods per plant,100-seed weight and some other indicators,which indicated selection of species should focus on the 9 traits consist of stem diameter,number of pods per plant,100-seed weight and other 6 traits indicators.Principal component analysis can be extracted five main components to reflect these 14 traits' information,cumulative contribution rate was 67. 29%. According to the principal component score and the weight calculation of this composite score,55 soybean varieties into three categories can be clustered. The thicker stem,more pods per plant,higher 100-seed weight and moderate growth period of the first category are suitable for intercropping with corn in Huanghuai region.
