选用3个核背景不同的恢复系材料和7个不同的哈克尼西棉胞质不育材料作为亲本,根据NCⅡ遗传交配设计,配置了21个杂交组合,分别在黄河流域棉区河南安阳、黄淮流域棉区河南西华和长江流域棉区安徽无为3个生态区试点种植,通过性状调查与室内考种,采用朱军的ADE模型,进行数据分析。结果表明,子棉和皮棉产量主要受到加性、显性、加性与环境互作效应的影响,衣分和铃数主要受加性、加性与环境互作效应的影响,而铃重则只受加性与环境互作效应的影响;对于纤维品质性状,纤维长度、马克隆值、比强度和整齐度受到加性效应的影响,同时,纤维长度和马克隆值还与加性与环境互作效应相关;遗传率分析与遗传方差分量分析表现一致;产量及产量性状之间有一定的遗传相关,而纤维品质性状之间的遗传相关则较小,产量和纤维品质性状之间也存在着较少的遗传相关;杂交组合的产量竞争优势表现为安阳试点>西华试点>无为试点,说明与生态环境有关。在3个不同的生态区,研究了21个杂交组合的遗传效应及优势表现,研究结果对三系杂交组合选配有一定的指导意义。
Three restorer lines with different nuclear backgrounds and seven different Huckish-West cytoplasmic male sterile materials were selected as parents. According to NCⅡ genetic mating design, twenty-one hybrid combinations were set up in the cotton area of Anyang, Henan, Huanghuai Valley cotton area in Henan Xihua and Yangtze River cotton area Anhui Inaction three ecological zones pilot planting, through the investigation of traits and indoor test species, the use of Zhu Jun’s ADE model for data analysis. The results showed that the yield of cotton seed and lint cotton were mainly affected by the additive effect, the dominant effect, the additive effect and the environment interaction effect. The boll number and boll number were mainly affected by the additive effect, additive effect and environmental interaction effect, while the boll weight Only by the additive effect and environmental interaction effect; for fiber quality traits, fiber length, micronaire value, specific strength and uniformity are affected by the additive effect, at the same time, fiber length and micronaire value and additivity and the environment The genetic analysis showed that the genetic analysis was consistent with the analysis of genetic variance components. There was a certain genetic correlation between yield and yield traits, but the genetic correlation between fiber quality traits was small, and there was also between yield and fiber quality traits With less genetic correlation; Yield combinations of hybrid combinations showed Anyang pilot> Xihua pilot> Inaction pilot, indicating that the ecological environment. In three different ecoregions, the genetic effects and the superiority of 21 cross combinations were studied. The results of the study have some guiding significance for the selection of three-line cross combinations.
