利用10个优异纤维品质陆地棉品种和6个转Bt基因抗虫棉品种配组的10×6 NCII交配设计，对其产量、品质及抗虫性的配合力及遗传效应进行了分析。结果表明：Bt基因能在F1得到显性遗传。以A8的产量性状一般配合力最高，A4的纤维品质性状一般配合力最高；A7×B5、A6×B1等组合的各性状特殊配合力较好；亲本的一般配合力与组合间特殊配合力不存在显著相关性。遗传效应分析表明，基因加性效应对铃重、衣分、2.5%跨长、比强度、伸长率等性状起主导作用；双亲的互作效应对F1产量性状起重要作用；2.5%跨长、铃重、比强度的狭义遗传力较高，产量性状的狭义遗传力最低。
Abstract
Combining ability and genetic effects of yield and fiber quality characters were investigated by way of 10×6 NCII cross design with 10 super fiber varieties and 6 insect-resistant transgenic varieties. The results showed that, Bt gene was dominant inheritance in F1 hybrids. A8 showed the best general combining ability (GCA) in yield characters, A4 expressed the best GCA in fiber quality characters. Combinations of A7×B5, A6×B1 expressed higher specific combining ability(SCA). But the GCA of parents and SCA of combination have no significant correlation. Genetic effects analysis showed that the additive variation was principal in boll weight (BW), lint percentage (LP), span length (SL), fiber strength (FS), elongation rate (ER). While seed cotton yield (SCY) and lint yield (LY) mainly by their interactions. SL, BW and FS had high narrow heritability (HN2), while SCY and LY were had low HN2.
