    摘要:

    以205 份中国冬麦区小麦品种(系)为材料,分析其籽粒植酸含量做聚类分析并解析其关联位点。结果表明,两个环境群体植酸含量平均值为4.99 g/kg和3.31 g/kg,变幅分别为17.90 g/kg和10.20 g/kg,变异范围较大。聚类分析将群体材料聚为6类,类间植酸含量差异均显著。推广品种或骨干亲本中,B54、B40、B86和B126植酸含量最低,可做为低植酸小麦育种中重要的亲本。高代品系B131、B141、B181和B149植酸含量最低,结合优异农艺性状,有望选出低值酸含量功能性小麦新品种。共检测到36个与小麦籽粒植酸含量显著关联的单核苷酸多态性(SNP)标记关联位点(P<0.001),分布在2B、3A、3B、3D、6A和6B染色体上,单个关联位点表型变异贡献率为5.73%~9.69%;鉴定出了低值酸含量基因的优异等位变异如Tdurum_contig35799_208-G、Excalibur_c96134_152-C和Tdurum_contig43538_1687-A等对低植酸含量效应较大。

    Abstract:

    In this study, 205 elite wheat lines from winter wheat region of China were used as materials to analyze the phytic acid content, and the cluster analysis and related was further conducted. The results showed that the average Phytic acid content of the two environmental groups was 4.99 g/kg and 3.31 g/kg, and the variation range was 17.90 g/kg and 10.20 g/kg, respectively. The variation range was relatively large. The results of cluster analysis showed that there were significant differences in Phytic acid content among 6 groups. B54, B40, B86 and B126 have the lowest phytic acid content among the extended varieties or backbone parents, which can be used as important parents in low Phytic acid wheat breeding. The higher generation lines B131, B141, B181 and B149 had the lowest phytic acid content. Combined with excellent agronomic traits, it is expected to select new functional wheat varieties with low Phytic acid content. A total of 36 single nucleotide polymorphism (SNP) markers associated with phytic acid content in wheat grains were detected (P < 0.001), which were distributed on chromosomes 2B, 3A, 3B, 3D, 6A and 6B. The contribution rate of phenotypic variation of a single Association site was 5.73% ~ 9.69%.Excellent alleles of genes with low Phytic acid content were identified such as tdurum, were identified_contig35799_208-G、Excalibur_c96134_152-C and tdurum_contig43538_1687-A, etc. which had a greater effect on low Phytic acid content.
