摘要
为了解河北省大豆资源情况及其分类特性,对115份河北省大豆品种的主要农艺性状进行了测定和聚类分析。结果表明,株高、分枝数、单株荚数、单株粒数变异较大;单株粒重、百粒重变异为中;主茎节数、生育期变异较小。通过聚类分析,当阈值为0.65时,供试材料被划分为5个性状不同的类群,各类群的农艺性状差异明显,有利于育种目标的选择。
Agronomic traits and cluster analysis of 115 soybean varieties were conducted. The results indicated a high level of variation in plant height, number of branches and pods per node but medium level of variation was observed in yield per plant and seed weight. Whereas variation in nodes and growth period was of low level. By the cluster analysis the material was classified into 5 groups when the threshold was 0.65. Each group had obvious features, so it would be helpful for cultivar selection.
