Genome and GWAS analyses for soybean cyst nematode resistance in USDA world-wide common bean (<i>Phaseolus vulgaris</i>) germplasm.

ABSTRACT: Soybean cyst nematode (SCN), Heterodera glycines, has become a significant threat in common bean (Phaseolus vulgaris) production, particularly in regions like the upper Midwest USA. Host genetic resistance offers an effective and environmentally friendly approach to managing SCN. This study aimed to conduct a genome-wide association study (GWAS) and genomic prediction for resistance to SCN HG Types 7 (race 6), 2.5.7 (race 5), and 1.3.6.7 (race 14) using 0.7 million whole-genome resequencing-generated SNPs in 354 USDA worldwide common bean germplasm accessions. Among these, 26 lines exhibited resistance to all three HG types, with a female index (FI) of less than 10. Four QTL regions on chromosomes (Chr) 2, 3, 6, and 10 were associated with resistance to HG Type 7; four region
