摘要
以辽宁地区水稻育种的主要亲本为试验材料,利用SSR分子标记技术对其遗传多样性和亲缘关系进行分析。并应用52个SSR标记对55个粳稻材料进行了遗传多样性分析。结果表明:在55个标记中,有18对引物具有多态性,共检测到等位基因83个平均每个标记3.75个。品种间相似系数在0.71～0.97之间,相似性较高,以0.82为标准,可分为8个大群,但主要生产应用品种多集中在第一大群中,显示出较近的亲缘关系,遗传基础相对单一。
The Japonica Rice Backbone Parental of Liaoning Province were used as materials to analyze the genetic diversity and genetic relationship by 52 SSR markers.AS a result,18 SSR markers showed polymorphisms,amounting to 42.5%. Selecting 18 pairs of SSR primer s with clearing ,stable ,significant difference band to study Genetic diversity furtherly. The average allelic numbers is 3.75 of 83. The Similarity coefficient is between 0.71-0.97o Using0.82 as a standard ,all Material s can be Divided into 8 groups ,but most are in one group .The result show that the Material s is The genetic basis of a single.
