Integrative genome-wide association and haplotype-based analyses reveal genetic structure and local adaptation in Korean landrace soybeans.

ABSTRACT:

Background

Soybean (Glycine max L.) is a major crop valued for both food and industrial applications. The genetic diversity preserved within landrace accessions serves as a critical resource for improving agronomic traits and enhancing adaptation to climatic variability. Korean landrace soybeans, shaped by long-term cultivation across diverse local environments, provide an ideal population for dissecting genetic variation underlying key traits and regional adaptation.

Results

A genome-wide association study (GWAS) was performed on 1,693 Korean landrace soybean accessions genotyped with 67,222 SNPs from the 180 K Axiom^® Soya SNP array. Population structure and genetic diversity were assessed using model-based stratification (K = 15), principal component analysis (P
