Analysis of Genetic Polymorphic SSR Markers in Germplasm Resources of the Natural Colored Cotton

摘要

Short sequence repeats (microsatellite,SSR) and expressed sequence tags-SSR (EST-SSR) markers were employed to analyze the genetic diversity of natural colored cotton varieties.About 490 pairs of SSR markers spanning the 26 chromosomes were selected from the cotton microsatellite database,they were composed of the NAU,BNL,MUSS,and CIR markers,and there was one marker every 5 cM on average.
