| 摘 要： | 利用SRAP分子标记技术对14份不同地理来源的油莎豆资源进行分析,研究其遗传基础和遗传多样性.结果表明,38对具有多态性的SRAP引物组合共扩增出375条带,其中多态性带共306条,多态性条带比率为81.6％,平均每对引物组合的多态性条带为8.1条.UPGMA聚类分析表明,14个参试材料间的遗传距离在0.09至0.72...

| Abstract: | Genetic diversity of 14 tigernuts collected from different geographical regions was investigated with SRAP molecular markers.The results showed that total 375 bands were amplified by 38 primer pairs,and 306 of these bands were polymorphic.The average polymorphic bands detected per primer pair were 8.1.Clustering with UPGMA method revealed that the genetic distance ranged from 0.09 to 0.72 with an average of 0.37.The largest genetic distance was 0.72,between accession No.8 and No.9.This research indicated th... |
