1990～1995年从陆海棉种间杂交后代分离筛选的6个典型铃后代作为试验研究材料，在杂交困、杂种固和鉴定因共255个处理中挂牌调查了3354个棉铃的10个性状，通过分组和对总体进行相关分析和方差分析，弄清了棉铃10性状间的相关性及大中小棉铃各性状的差异性。
From 1990 to 1995, six typical boll back progenies isolated from interspecific hybrids of land and sea cotton were selected as experimental materials. Ten traits of 3354 cotton bolls were surveyed in a total of 255 treatments for hybridization, hybrid identification and identification. By grouping and analyzing the population as a whole and analyzing the variance, the correlation between the traits of cotton bollworm 10 and the traits of bollworm were analyzed.
