小麦新品种基因型和环境效应分析

本文利用山东省１９９４年小麦品种联合区域试验材料，用Ｔａｉ法对小麦亩穗数、穗粒数、千粒重、亩产量进行了基因型和环境效应分析。结果表明，繁茂型中穗中粒基因型品种比大穗大粒基因型品种具有更大的增产潜力；环境效应及基因型与环境互作效应对各品种都有显著影响，在良好的环境条件下，繁茂型中穗中粒基因型品种比大穗大粒基因型品种增产更显著。

New Winter Wheat Varieties:Genotypes and Environment Effectiveness

nalysis of genotypes in relation to environments revealed that luxuriant genotypic varieties with medium-spike and medium-grain had greater potentialities of yield-increasing than the genotypic varieties with large-spike and large-grain,especially under good environment conditions.Environments and interaction of genotypes with environments significantly affected yielding of all varieties.
