产量相关优异等位变异在小麦骨干亲本阿夫及其衍生后代中的分布
Distribution of yield-related favorable alleles in wheat founder parent Funo and its derivatives
摘要
Abstract
[Objective]To explore the way that the favorable alleles at the reported loci of kernel number per spike(KNPS)and thou-sand kernel weight(TKW)were distributed in the founder parent Funo and its derived varieties in Henan province,and to interpret the roles of Funo in wheat breeding at molecular level.[Methods]The genotypes of the 26 simple sequence repeat(SSR)loci in both Funo and 18 samples of derivatives were scanned and analyzed by ABI3730.[Results]The 26 SSR loci were distributed on 13 chro-mosomes,and the major allele frequencies ranged between 0.211 and 0.889(mean 0.557).The number of corresponding alleles varied from 2 to 9.The polymorphism information content varied from 0.194 to 0.830(mean 0.512).19 samples were divided into three clusters by neighbor-joining(NJ)cluster analysis.Analysis of favorable alleles showed that Yu 30691-1-3,the fourth genera-tion of Funo,carried the largest number(8)of KNPS-related favorable alleles,while Kaifeng10,the first generation of Funo,car-ried the largest number(8)of TGW-related favorable alleles.[Conclusion]Funo and its derivatives cultured in Henan cover all 26 yield-related favorable alleles.This finding partly explained the reason that these derived varieties are the most popular clutivars planted in Henan province at the molecular level.关键词
