东北大豆品种资源的遗传研究

Genetic Study on Northeast Soybean Varieties

本文通过对不同来源的64份地方品种在长春种植3年的试验,估算了8个性状的遗传力,并进行了遗传、表型、环境通径分析。结果表明:①来源于吉林的33个品种适应性较强,并以荚数、株高、百粒重对单株粒重的直接贡献大。②来源于黑龙江的20份品种大部分性状遗传力高于吉林品种,并以荚数、株高对单株粒重的直接贡献大。③来源于辽宁的11份品种诸性状遗传力均高于吉林品种,它以粒数、百粒重、荚数、分枝对单株粒重的直接贡献大。

The heritability of eight characters were measured by using 64 kinds of varieties which were planted three years.
