摘要
小麦幼苗生长习性是小麦苗期重要的农艺性状,为了挖掘控制小麦幼苗生长习性相关性状的基因位点,本研究以210个遗传变异丰富的小麦品种(系)组成的自然群体为试验材料,分别于2021-2023年种植于河北省唐山市,利用高通量测序技术对小麦幼苗生长习性进行全基因组关联分析.结果表明,共有11个与小麦幼苗生长习性显著关联的SNP位点(区段),分布于1B、2A、3B、5A(3)、5B(2)、6D、7B、7D染色体上,其中,在多个环境中被检测到的位点(区段)有3 个,分别位于染色体 5A(512.39 Mb)、5B(605.61～605.63 Mb)、7B(610.85 Mb)处.
Abstract
The growth habit of wheat(Triticum aestivum L.)seedlings is an important agronomic trait in wheat seedling stage.In order to explore the gene loci that control the growth habit related traits of wheat seedlings,a natural population consisting of 210 wheat varieties(lines)with abundant genetic variation was used as experimental materials,which were planted in Tangshan,Hebei Province from 2021 to 2023,respectively.High-throughput sequencing technology was used to study the growth of wheat seedlings Genome-wide association analysis was performed.The results showed that there were 11 SNP loci(segments)significantly associated with the growth habits of wheat seedlings,which were distributed on chromosomes 1B,2A,3B,5A(3),5B(2),6D,7B and 7D,among which 3 loci(segments)were detected in multiple environments,respectively on chromosomes 5A(512.39 Mb)and 5B(605.61 to 605.63 Mb),7B(610.85 Mb).
