摘　　要：通过对4个棉花品种(系)百棉1号、百棉6号、豫棉668、海南109的30个不同铃位棉铃的8个主要经济性状的广义遗传力进行聚类分析,最终确定出棉花遗传变异最小的铃位为第4-1、5-1、6-1铃位,遗传变异最大的铃位为第6-3、7-1、7-2。The test carried out clustering analysis to the eight mainly economy character of 30 different part bell on BM1, BM6, YM668 and HN109. The result showed that the inheritance variance coefficient of theⅠ kind was least, the 4-1, 5-1, 6-1 were the steadiest positions in inheritance breeding practice. The inheritance variance coefficient of the Ⅳ kind was most,the 6-3, 7-1, 7-2 were the least steady positions in inheritance breeding practice.
