| 摘 要： | 根据加性－显性与环境互作的遗传模型，提出了利用多个环境的杂交亲本和Ｆ＿１的资料，采用ＡＵＰ法预测作物杂种后代在不同环境中的基因型值和杂种优势的分析方法。作为分析实例，本文对１９９２年和１９９３年陆地棉（ＧｏｓｓｙｐｉｕｍｈｉｒｓｕｔｕｍＬ．）杂交亲本（Ｐ）、Ｆ＿１皮棉产量和衣分的两年资料进行了分析。

| Abstract: | Methods of predicting genotypic value and heterosis of crop hybrids in different envi-ronments were proposed for data from parents and F_1s of crops, by an AUP prediction approache based on a genetic model of additive-dominance and environment interactions.Lint yield and lint percentage of 10 parents and their 20F_1s of Upland cotton(Gossypium hirsutum L.)in two years were analyzed as an example. |
