配合力是杂交组合中亲本各性状配合能力的一个指标。配合力的分析无论是对选育强优势的杂交种还是优良的纯合体品种,选育和鉴定具有高配合力的亲本品系或自交系都是一个非常重要的课题。在近代的玉米杂种优势利用研究中,广泛利用配合力的研究结果,使玉米杂交种的选育不断取得新的突破。在水稻育种和杂种优势利用中,国内外许多学者也进行了研究。不同的研究者由于利用的试验材料或自然条件等不同,所得结 Combining ability is an index of the ability of parental traits in hybrid combinations. Analysis of Combining Ability Breeding and identification of parental lines or inbred lines with high combining ability are both very important topics for both breeding and predominant hybrids. In the modern research on the utilization of maize heterosis, the research results of combining ability were extensively used to make new breakthroughs in the breeding of maize hybrids. In rice breeding and utilization of heterosis, many scholars at home and abroad have also carried out research. Different researchers due to the use of test materials or natural conditions, such as different ends
