轮回选择法是玉米育种的主要方法之一。通过轮回选择,可提高群体内有益基因累加和增加群体内的变异。作物产量是数量性状的表现,其遗传的特点是多基因群控制,对产量有利的基因与不利基因会相互连
Recycling selection is one of the main methods of maize breeding. By reincarnation, beneficial gene accumulation in the population can be increased and variation within the population can be increased. Crop yield is a manifestation of quantitative traits, and its inheritance is characterized by the control of multiple gene clusters, with genes favorable for yield and unfavorable genes interconnected
