SSR analysis for genetic diversity of Malus sieversii from Xinjiang, China
摘要
Abstract
In order to provide theoretical basis for crossbreeding and high-quality breeding, the genetic diversity of 180 Malus sieversii individuals from 7 populations in Xinjiang was investigated using SSR markers. 119 bands were amplified by thirteen pairs of SSR primers and the polymorphic loci （P） ratio a- mong these populations ranged from 79.84% to 92.25%. At population level, the variation trend of genetic diversity of M. sieversii was consistent. The effective number of alleles Ne, gene diversity Nei＇s and Shannon＇s information indexes of Xinyuan population were the higherst among the seven populations. At species level, Shannon＇ s information index was 0.551 6, and 0.468 9 at populations level. The genetic di- versity of intro-population and inter-populations were 15% and 85% respectively, which indicated that the aberrance ofM. sieversii populations mainly occurred in inter-populations.关键词
