| 摘 要： | 本文对12个杂种及其7个亲本在八个环境条件下的表现进行了稳定性分析。杂种(或亲本)之间的稳定性具有较大差异,杂种单株籽粒产量比亲本对环境反应敏感,倾向于或超过不稳定的亲本。F_1代杂合体并没有增加稳定性的表现。在面团品质性状上,存在着基因型与环境的互作。采用回归系数和决定系数进行稳定性分析,较好地反映了基因型对环境反应的实际情况,它不失为一种测定作物新品种稳定性的有效方法。

| Abstract: | The stabilities of yields and protien contents of 12 hybrids and their parents
at eight environments were analysed.There were great differences among the
stabilities of hybrids or parents.The response of grain yield of hybrid to env-
ironment was greater than that of their parents.To the characteristics of ba-
king quality,there were genotype environment interaction.The coefficients
of regression and determination were used effectively to measure the stability of
the response of genotype to various environments. |
