利用分子标记检测的方法，对不同水稻品种间的淀粉合成相关基因的基因型进行了系统筛选。结果显示，淀粉合成相关基因在籼粳亚种间表现出较好的多态性，在籼亚种内存在较大变异，在粳亚种内较为保守，籼稻品种9311和明恢63的基因型更接近于粳稻品种；在28个粳稻亲本中检测到6个淀粉合成相关基因存在着2种或3种等位基因型。利用在关东194和武粳13之间具有多态性的可溶性淀粉合成酶基因SSIIa和SSIIIa的分子标记，在其杂交后代88份粳稻品系中检测到2个基因的4种基因型。

The genotypes of starch synthesis genes were systematically screened in different rice varieties by means of molecular marker detection. A great number of polymorphisms of the genes were identified within indica and japonica rice with 48 molecular markers out of 83. The starch synthesis-related genes were highly conserved in indica rice and were high-ly diversed in japonica rice. Genotypes of indica varieties 9311 and Minghui 63 were closer to those of japonica varieties. Two or three alleles of six starch synthesis-related genes were found in 28 japonica parents. Four genotypes of the two solu-ble starch synthase genes,SSIIa and SSIIIa,were detected in 88 breeding lines derived from the cross of Kanto 194/Wujing 13 by using the molecular markers.
