| 摘 要： | 通过１２×６个小麦品系不完全双列杂交，对供试亲本及其杂交组合的产量配合力与产量因素性状配合力间的关系进行了研究。结果表明：籽粒产量的配合力相对效应值近似等于３个产量构成因素的配合力相对效应值之和，也近似等于生物产量配合力相对效应值与收获指数配合力相对效应值之和。杂种Ｆ＿１代的籽粒产量是各组合产量总平均值及其与９种配合力相对效应值（产量３因素的双亲一般配合力和组合特殊配合力的相对效应值）乘积相加的产物。此外，还讨论了根据配合力选配强优势组合的问题。

| Abstract: | 72 F1s derived from a 12×6 incomplete diallels were used to study the
combining ability relationship between yield and its components in hybrid wheat.It was
showed that the relative value of the combining abilities of grain yield approximately equals to the sum of that of three yield components,or to the sum of that of biomass and
harvest index.The practical grain yield of across was the results of the average yield of
toral crosses added by the products of it multiplied by nine kinds of relative value of
combining abilities (RGCA and RSCA for three yield components)respeetively.In addition,the way how to choose parental materials for higher heterosis was disecussed according to the combining abilities. |
