选用洞Ａ不育株，６个胞质不育系和４个胞质不育系的恢复系，按７×４不完全双列杂交设计，对２８个组合的Ｆ１进行双列分析。结果表明，皮棉产量、衣分、衣指、子指、２．５％跨长、比强度、纤维细度、单纤强力主要受加性基因控制，子棉产量主要受非加性基因控制；洞Ａ是较好的不育材料，南Ａ１２是优质的胞质不育系，南Ｒ２是较好的恢复系；洞Ａ×Ｇ９３００５是双亲ＧＣＡ和组合ＳＣＡ均较高的高产组合。
The restorer lines of sterile line Dong-A, six cytoplasmic male sterile lines and four cytoplasmic male sterile lines were selected. Based on the 7 × 4 incomplete double-line crosses, F1 combinations of 28 combinations were double-stranded analyzed. The results showed that the lint yield, lint percentage, finger index, 2.5% cross length, specific intensity, fiber fineness and single fiber strength were mainly controlled by additive genes. The yield of cotton seed was mainly controlled by non - additive gene. Cave A is a better sterile material, South A12 is a good cytoplasmic male sterile line, and South R2 is a better restorer line. Cave A × G93005 is a high-yielding combination of both GCA and SCA.
