本研究根据加性-显性与环境互作的遗传模型,分析了陆地棉10个杂交亲本和20个F1皮棉产量、单株铃数、单铃重、衣分和前期收花率的两年资料,估算了各项遗传方差分量和成对性状间各项遗传效应的相关。方差分析结果表明,衣分受基因型×环境互作效应影响较小,其它4个性状受基因型×环境互作影响较大,其中皮棉产量、单株铃数和前期收花率受显性×环境互作效应影响较大。遗传相关分析表明,皮棉产量与单株铃数、衣分和前期收花率加性相关系数值较大,皮棉产量与单株铃数、单铃重和前期收花率间存在较强的加性与环境互作负相关。皮棉产量与单株铃数、单铃重和前期收花率间存在显著的显性正相关,但与单株铃数、单铃重间存在显性与环境互作相关。
Based on the genetic model of additive-dominance and environmental interaction, the present study analyzed the effects of two years on the yield and the number of bolls, boll number, boll weight, Data to estimate the genetic variance components and pairs of traits between the genetic effects of the correlation. Analysis of variance showed that there was little effect of genotype × environment interaction effect on the litter size, and the other four traits were greatly influenced by the genotype × environment interaction. The yield of lint, number of bolls per plant, × Environmental interaction effects have a greater impact. Genetic correlation analysis showed that the correlation coefficient between lint yield and boll number per plant, lint percentage and pre-harvest rate was large. There was a strong increase between lint yield and boll number per plant, boll weight and pre-harvest rate Negative correlation between sex and environment. There was a significant positive correlation between lint yield and boll number per boll, boll weight and initial bolting rate, but there was a significant positive correlation with boll number and boll weight per plant and environmental interaction.
