Unveiling key genetic determinants of charcoal rot resistance in soybean via genome-wide association studies.

ABSTRACT: Charcoal rot is a soil- and seed-borne disease caused by a necrotrophic fungal pathogen-Macrophomina phaseolina. To understand the genetic architecture of resistance against it, a genome-wide association study (GWAS) was conducted based on a glasshouse experiment and a 3-year field experiment using 214 diverse soybean accessions. In a glasshouse experiment at the seedling stage, eight single-nucleotide polymorphisms (SNPs) were identified: one SNP each on chromosome (chr) 8 (S8_16817767), chr 10 (S10_52066337), chr 14 (S14_50857981), chr 15 (S15_32620059), chr 17 (S17_1689021), and chr 18 (S18_9413708), while two SNPs (S16_34569104 and S16_37878937) were located on chr 16. In the case of the field experiment at the reproductive
