本文采用方差分析法，估计了春蚕豆新品种青海9号原始群体中主要性状的遗传参数。结果表明：青海9号原始群体中仍有一定程度的遗传变异。单株实荚数、粒数、有效分枝和单株粒重的遗传变异系数较大，达10％以上；百粒重和株高的遗传力较高；在5％的选择强度下，主要产量性状可获得10％以上的相对遗传进度。对1995～1997年青海9号蚕豆原种繁育的考种资料进行分析，探讨了主要性状的选择效果和方法。
In this paper, variance analysis was used to estimate the genetic parameters of the main characters of the spring broad bean new variety Qinghai 9. The results showed that there was still a certain degree of genetic variation in the original population of Qinghai 9. The coefficient of variation of plant pod number, grain number, effective branch and grain weight per plant was larger than 10%, and the heritability of 100-grain weight and plant height was higher. Under the 5% selective intensity, the major Yield traits can get more than 10% relative genetic progress. This paper analyzed the test materials of breeding of broad bean in Qinghai on 1995-1997 and discussed the selection effect and method of the main characters.
