阐明了数量遗传学的发展概况以及在当今育种领域应用的重要性,同时通过玉米产量及其相关性状配合力、遗传力的分析,探讨了玉米产量及其相关性状育种的建系和选择方法,特别指出了种植密度在产量鉴定试验中的作用,为更好地开展玉米育种服务。
The development of quantitative genetics and the importance of its application in breeding fields are clarified. At the same time, the establishment and selection of breeding methods of maize yield and its related traits are discussed through the analysis of the combining ability and heritability of maize yield and its related traits. In particular, the role of planting density in yield test was pointed out, in order to better carry out maize breeding services.
