An additive dominance genetic model with genotype by environment interaction and corresponding statistical approaches were applied to analyze the number of bolls and seed cotton yield per plant at different fruiting stages in 1995,1996 obtained from 12 Upland cotton ( Gossypium hirsutum L.) parents and their 17 F 1′s hybrids. It was showed that GE effects were predominant at early fruiting stage for the number of bolls per plant. Additive and dominance effect, however, played a more important role at mid fruiting stage while GE effects reduced continually. At late fruiting stage additive effects and DE effects increased, but dominance effects decreased. GE effects were predominant at early fruiting stage for the seed cotton yield per plant. At mid fruiting stage, V A was not detected while V D was continuously increasing. At late fruiting stage, V A was significant. For boll number per plant conditional additive effects were detected at all different fruiting stage while dominance effects were only found before August 7. Conditional AE was detected at a few stages, but conditional DE was found at most stages. Gene expression was most active during July 26 to August 7 in 1995, 1996. For seed cotton yield per plant, gene expression was very similar to boll number per plant, but conditional dominance and DE effects were significant at most stages. Significant positive correlation was found between total boll number per plant and total seed cotton yield per plant, but significant negative correlation existed between boll number per plant before July 26 and total yield per plant. Additive correlation between early seed cotton yield and total seed cotton yield were significantly negative while dominance correlation was significant positive.

采用包括基因型与环境互作的加性-显性遗传模型,分析了1995年,1996年陆地棉(GosypiumhirsutumL.)12个亲本及其17个F1组合不同花铃期的单株成铃数和单株籽棉产量.遗传效应分析表明:单株成铃数在花铃前期以GE互作效应为主;花铃中期加性效应和显性效应有所增加,而GE互作效应逐渐减小;花铃后期加性效应仍继续增加,而显性效应则减小,DE互作效应明显上升.单株籽棉产量在花铃前期主要受GE互作控制;花铃中期未检测到加性方差,而显性方差持续增加;花铃后期存在显著的加性效应.净遗传效应分析表明:单株成铃数在整个花铃期都有加性效应的表达,而显性效应仅在8月7日前检测到,在少数时期也检测到条件加性×环境互作效应,条件显性×环境互作效应则在多数时期均检测到.其中7月27日至8月7日是单株成铃数基因表达最为活跃的时期.单株籽棉产量的基因表达与单株成铃数相似,但条件显性效应和条件显性×环境互作效应在多个时期均显著.单株总铃数与单株籽棉总产量的各项相关系数均为显著正值,但7月26日前单株铃数与单株籽棉总产量存在显著的加性负相关.早期单株籽棉产量与单株籽棉总产量是极显著的加性负相关和显著的显性正相关
