利用４个隐性低酚棉品系为母本，５个显性无腺体品系为父本，按不完全双列杂交（ＮＣⅡ）设计配制２０个组合，利用亲本、Ｆ１和Ｆ２材料采用ＡＤＡＡ模型研究表明，衣分以加性效应为主，其余产量及产量构成因素以显性遗传效应为主。子棉产量和铃重有较低的上位遗传效应。纤维品质性状中，绒长与整齐度以显性遗传效应为主，绒长还存在少量上位效应；比强度与伸长率仅存在显著的加性遗传效应，麦克隆值以加性遗传效应为主。Ｆ１皮棉产量、第一次收花率、单株铃数、铃重和衣分的群体超亲优势平均值分别为：２７．９％、１８．７％、１６．２％、９．７％和１％，Ｆ２分别为：１０．８％、５．１％、４．５％、４．６％和－１．２％。Ｆ１绒长的群体平均优势为２．５％，比强度和伸长率为－１．８和０．８％，麦克隆值和整齐度分别为－０．２％和－２．７％。Ｆ２绒长略呈下降趋势，比强度、伸长率和麦克隆值Ｆ２与Ｆ１相近，整齐度Ｆ２略优于Ｆ１。表明了显性无腺体基因的杂种优势利用前景广阔。
Four recessive low phenol cotton lines as female parent and five dominant gonadal lines as male parents were used to construct 20 combinations according to incomplete diallel cross (NCⅡ) design. The ADAA model Studies have shown that the main additive effect of clothing, the rest of the output and yield factors dominated by dominant genetic effects. Cotton yield and boll weight have a lower epistatic effect. In the fiber quality traits, the dominant length and uniformity of the velvet length were dominated by dominant genetic effects while there was a slight epistatic effect in the velvet length. There was only a significant additive genetic effect on specific strength and elongation. The micronaire value was additive genetic effect the Lord. The average transfrontal heterosis of F1 lint yield, first harvest rate, number of bolls per plant, boll weight and lint percentage were 27.9%, 18.7%, 16.2% and 9.7% And 1%, respectively, F2: 10.8%, 5.1%, 4.5%, 4.6% and -1.2%. The average length of F1 population was 2.5%, the specific intensity and elongation were -1.8 and 0.8%, and the micronaire and uniformity were -0.2% and -2.7%, respectively. The length of F2 cashmere slightly decreased, which was similar to the strength, elongation and micronaire value of F2 and F1, and the uniformity of F2 was slightly better than that of F1. It indicated that the heterosis of dominant glandless gene was promising.
