The invention discloses SNP (Single Nucleotide Polymorphism) loci related to high yield and drought resistance of wheat and application of the SNP loci. The SNP loci are located at 41bp, 633bp and 676bp of physical positions of 3B chromosomes of the wheat, and the nucleotide polymorphism of the SNP loci is shown as C/T; the effect is to regulate and control thousand seed weight and/or grain length of wheat. The molecular marker has high practical value for high-yield and drought-resistant breeding of wheat, lays a foundation for further cloning genes for controlling thousand seed weight and grain length of wheat in multiple environments, can be used for screening and identifying drought-resistant and high-yield wheat varieties in the early stage of molecular marker-assisted selective breeding MAS, and has a wide application prospect. The method has important scientific research and application values. 本发明公开了一种与小麦高产、抗旱相关的SNP位点及其应用，所述SNP位点位于小麦3B染色体物理位置第41,633,676 bp，其核苷酸多态性表现为C/T；其效用为调控小麦的千粒重和/或粒长。本发明对于小麦的高产、抗旱
