Genome-Wide Association Analysis between SNP Markers and Plant Height Related Traits in Wheat
摘要
Abstract
Plant height (PH) has great influence on yield potential and lodging occurrence in wheat (Triticum aestivumL.). In this study, the diverse panel of 205 elite wheat lines was genotyped with the 90k SNP array (24 355 SNPs) based on the Illumina In-finium assay to disclose the PH genetic mechanism. A total of 38 SNPs were found to be associated with PH (P < 0.0001), which were located on chromosomes 1B, 2A, 2B, 3A, 3B, 3D, 4A, 4B, 5A, and 6D, including 11 SNPs detected in two or more envi-ronments. These stable SNPs can be used to develop CAPS markers for PH. In which, a few elite alleles were identified, such as BobWhite_c48009_52 to reduce PH by 12.9 cm, and BS00039422_51-C and IAAV1698-A to decrease length of the first inter-node below spike by 5.9 cm and 6.6 cm, respectively. These results will facilitate further researches in PH-related traits in wheat.关键词
