基于160K SNP液相芯片的新疆冬小麦骨干亲本遗传多样性分析
Genetic Diversity Analysis of Xinjiang Winter Wheat Backbone Parents Based on 160K SNP Liquid Chip
摘要
Abstract
In order to provide theoretical supports for parent selection and variety(line)breeding of Xinjiang winter wheat,the genetic differences,genetic relationships,population structure,multi-dimensional scale and genetic evolution of 25 winter wheat varieties(lines)in Xinjiang were analyzed using 160K SNP liq-uid chip.The results showed that the distribution of SNP sites on 21 chromosomes ranged from 24 688 to 142 995 with an average of 88 828.The distribution of the 7 homologous groups ranged from 179 686 to 345867 with an average of 266 482,and their distribution on the genomes showed the trend of B genome＞A ge-nome＞D genome.The average sequencing depth of the 25 varieties(line)was 5.41 ×,the heterozygosity dis-tribution range was 1.83％to 17.87％,and the average heterozygosity rate was 6.96％.Among them,Kendong 10-27 had a rich genetic background,and Xindong 20 had a distant relationship with other materials.Popula-tion structure analysis divided the 25 winter wheat into 3 subgroups,while multi-dimensional scaling analysis divided them into 5 subgroups,including 3,8,4,2 and 8 materials from each subgroup.The study clarified the genetic diversity distribution characteristics of 25 winter wheat backbone parents in genomic level by 160K SNP liquid chip,and the results could provide a theoretical basis for genetic improvement of Xinjiang winter wheat backbone parents.关键词
