配合力是杂交组合中亲本各性状配合能力的一种指标,无论对于选育具有杂种优势的杂交组合或是优良的纯合体品种,都是非常重要的课题。在水稻育种和杂种优势利用方面,国内近年才开始这项研究。本文以双列式杂交设计的研究资料,分析籼稻10种数量性伏的遗传表现,以期探讨亲本配合力效应和数量性状的遗传规律,为水稻育种和选育杂交水稻新组合提供理论依据。
Combining ability is an indicator of the ability of parents to cooperate with each other in a cross combination, which is a very important issue for breeding hybrid combinations with excellent heterosis. In the field of rice breeding and utilization of heterosis, this research was started in China in recent years. In this paper, we studied the genetic performance of ten quantitative volts of indica rice in order to explore the genetic rules of combining ability effect and quantitative trait of indica rice, and provided the theoretical basis for the new combination of rice breeding and breeding hybrid rice.
