选用 6 0个随机引物对 15份杂交粳稻亲本材料进行了RAPD分析 ,其中 10种引物的扩增结果具有明显的多态性。在这 15份杂交粳稻亲本材料中共扩增得到 153条条带 ,其中的86条为多态性条带。聚类分析结果表明 ,所有供试材料可以被明确区分。在此基础上分析了这15个水稻品种的亲缘关系 ,对田间育种有一定的参考价值。 Sixty random primers were used to analyze RAPD analysis of 15 parents of japonica hybrid rice. Among them, 10 primers showed significant polymorphism. A total of 153 bands were amplified by co-amplification in 15 parents of japonica hybrid rice, of which 86 were polymorphic bands. Cluster analysis showed that all the tested materials could be clearly distinguished. Based on this analysis, the genetic relationship among the 15 rice cultivars was analyzed, which had certain reference value for field breeding.
