配合力是玉米自交系的一个重要遗传特性。要选育出在生产上能够显著增产的玉米杂交种,主要取决于自交系的配合力。正确地理解配合力的概念,采用恰当的测交方法,对玉米育种工作的成效具有十分重要的意义。一般配合力与特殊配合力在玉米育种以双交种为选育目标时,通常是在自交早代测验选育材料的一般配合 Combining ability is an important genetic characteristic of maize inbred lines. To breed maize hybrids that can significantly increase production can depend on the combining ability of inbred lines. Correct understanding of the concept of combining ability, using the appropriate method of dating, is of great importance to the effectiveness of maize breeding. General Combining Ability and Special Combining Ability When maize breeding with double crosses is the breeding target, it is usually to test the general matching of breeding materials in the early selfing
