Genome-Wide Association Study on Cowpea seed coat color using RGB images.

ABSTRACT: This study delves into the genetic mechanisms underlying seed coat color variation in cowpeas (Vigna unguiculata [L.] Walp.), a trait with significant implications for nutritional value, consumer preference, and adaptation to environmental stresses. Through a genome-wide association study (GWAS) involving cowpea accessions exhibiting red, green, and blue seed coats, we identified 16 significant single nucleotide polymorphisms (SNPs) distributed across chromosomes 3, 4, 5, 9, 10, and 11. Our analysis highlighted the polygenic nature of seed coat color, emphasizing the shared SNP loci across different colors, suggesting integrated genetic influence or linked inheritance patterns, especially on chromosomes 9 and 10. We highlighted candidate genes, including Pentatricopeptide repeat fam
