贵州省花生地方品种的遗传多样性
Genetic Diversity of Peanut Landraces in Guizhou Province
摘要
Abstract
In order to assess the genetic diversity of peanut in Guizhou province and provide a theoretical basis for breeding, 68 accessions of peanut landraces collected from Guizhou province were evaluated by 50 SSR markers. Seventy-nine alleles were amplified by forty-one polymorphic SSR primer pairs. The average number of alleles per locus was 1.93 with a range from 0.045 to 0.951. Total Shannon information index per locus varied widely from 0.2518 (PM79) to 0.6826 (PM188) with an average value of 0.5268; total Nei's genetic diversity index per locus varied widely between 0.1699 (PM79) and 0.4995 (PM188) with an average value of 0.3556. Cluster analysis with UPGMA showed that the landraces could be divided into two groups and the genetic relationship among materials with similar seed sizes was not in accord with their geographical origins. The peanut landrace in Guizhou showed higher genetic diversity.关键词
