| 摘 要： | 本研究对7个小麦亲本和所有组合的21个杂种在4个环境中的6个性状进行了稳定性分析。结果表明:回归系数和非模式均方的遗传效应是不同的;在亲本对后代的影响方面,回归系数的作用明显大于非模式均方;回归系数的杂种优势较突出,而非模式均方的超亲遗传更明显;两种参数的育种应该采用不同的杂交模式。

| Abstract: | The paper presents the stability analysis on 6 characters of 7 wheat pa-rents and their 21 hybrid progenies of their all combinations in 4 enviro-ments.The result displays that the genetic effect of two stability parametersis different; for paraents influence on hybrid progeneies, regression coefficientis greater than non-mode mean square; the former's hybrid vigor is outstan-ding. but the latter's super-parent genetic more obvious; the two parameters'breeding should be adopted different hybrid models. |
