Genome-wide association study of pre-harvest sprouting resistance and grain color in common wheat (Triticum aestivum L.).

ABSTRACT:

Background

Pre-harvest sprouting (PHS) is a serious problem in wheat production globally. Grain color (GC) has a notable impact on PHS resistance, red grains typically show higher resistance compared to white grains. To understand the genetic factors influencing PHS and GC, a genome-wide association study (GWAS) was conducted on a natural population of 235 wheat cultivars using a 90 K single nucleotide polymorphism (SNP) arrays.

Results

A strong correlation between PHS and GC was observed, with the highest correlation coefficient of 0.85 (P < 0.0001). Association mapping was performed using four different models (BLINK, FarmCPU, MMLM and MLM) in the GAPIT along with MLM model in the Tassel. The study identified twelve stable quantitative trait loci (QTLs) related to PHS resi
