为阐明辽宁省育成粳稻的亲缘关系,以辽宁省9个育种单位育成的58个粳稻品种为材料,利用54对SSR分子标记对其进行遗传多样性和群体结构分析。结果表明,54对SSR引物中共有48对引物存在多态性,多态性引物占比88.89%。48对多态性引物共检测到150个等位基因,每个位点检测等位基因(Na)变异范围为2~6,平均为3.13;基因多样性指数(H)变异范围为0.03~0.78,平均为0.33;多态性信息含量(PIC)变异范围为0.03~0.74,平均为0.29。通过对不同育种单位育成品种对比分析发现,辽宁省盐碱地利用研究所育成品种的遗传多样性水平较高,平均PIC为0.30,平均H为0.34,而铁岭市农业科学院育成品种的多样性水平较低,平均PIC为0.11,平均H为0.14。NJ聚类分析表明,58个品种可以划分成3个类群,其中丹东农业科学院育成的丹粳系列与铁岭市农业科学院育成的铁粳系列分别位于类群Ⅰ和Ⅲ。基于模型的群体遗传结构分析表明,58个粳稻可以分为2个类群,其中32个材料属于类群A,26个材料属于类群B。

On the basis of many years of research at the laboratory, and by making reference to the related literature published at home and abroad, in this paper the concept of rice ideal panicle type was introduced, and the principles of rice ideal panicle type design were elucidated. The parame-ters of rice ideal panicle type for Liaoning were preliminarily established as follows: Panicle length 2 mm, large vascular bundle and primary branch >15 pieces/panicle, primary branch grain >80 grains/panicle, secondary branch grains concentrating in the middle and upper parts of panicle axis, and panicle type index >0.5. In addition, the possibility of achieving unity of grain yield and quality at a still higher level by creating an ideal panicle type was explored.
