摘  要：
32个细长粒形丝苗型的华南地区早籼稻优质品种数量性状的遗传距离进行聚类分析,分为5个类群。类群间差异比类群内大,水稻品质育种杂交亲本选配应在类群间进行。但在改良品种1—2个性状时,亲本之一符合育种目标,另一亲本也可不一定选用遗传距离大的品种。

摘  要：
Accordiug to genetic divergence and systematic cluster analysis of quantitative characters in 32 slender high grain quality varieties of rice ( Oryza sativa L. subsp. hsien.Ting ) in South China region.the varieties were classified into 5 types. The genetic divergence of different types was greater then the similar tyte. It is showed that selection parents for hybridization in rice breeding for slender high grain quality may be conducted between different types, but one of parents has fit the object of breedieg, when it will be only impoved 1 to 2characters, other pareut may be also not selected the variety of greater genetic divergence.
