| 摘 要： | 阐述水稻群体育种法的主要特质、关键性的育种技巧及育成品种的特征特性。论述群体育种法育成品种的超高产性与品种内适度的遗传学异质性之间必然的因果关系,即品种内的个体间存在适度的遗传学差异,有利于品种在较长时间的生产中保持田间抗病性、减缓品种退化、延长品种使用寿命,使品种在较长年限内维持较高的生产水平。

| Abstract: | The characteristics of population breeding,key skills and main features of varieties developed were discussed.There exists causality between super-high yield and genetic heterogeneity,that is,proper genetic differentiation consisting in individuals.It can help individuals keep disease resistance in field,slowing down retrogression,expanding life of variety,and maintaining high production level for a long time. |
