Association Analysis of Island Cotton Fiber Quality Traits
摘要
Abstract
Island cotton is famous for its superior fiber quality.Its fiber is longer,stronger and thinner.This study carried out associative analysis on its fiber quality,hoping to provide theoretical guidance for marker assisted selective breeding (MAS).214 accessions of island germaplasm resources genome were scanned with 194 SSR (simple sequence repeats) markers.The population structure and association of 8 fiber quality traits were analyzed by MLM (mixed linear model) of TASSEL software.The results showed that:① STRUCTURE analysis was carried out and 214 island germaplasm resources were divided into 4 subpopulations,mainly distributed in China,United States and former Soviet Union.The chairngorm and resources of its sub-populations had certain association.② 13 markers and 8 fiber quality traits were correlated analyzed by MLM method.The markers were relatively concentrated in 13 and 17 chromosomes.Among them,some markers were associated with 2 or more traits.This phenomenon might be caused by traits association or "pleiotropy" genetic basis.关键词
