Genome-wide association study of seed mineral nutrients in peas (Pisum sativum L.).

ABSTRACT: Pea (Pisum sativum L.) is an important crop with high nutritional value and agricultural benefits. This study aimed to identify genetic factors that influence the levels of mineral elements (B, Ca, Cu, Fe, K, Mg, Mn, Na, P, S, Zn, Co, Mo, Ni, and Se) in pea seeds. A panel of 482 genetically variable pea accessions was grown in field trials for 3 years (2019-2021) and the seed mineral nutrients were analyzed. Individual accessions in the panel were genotyped using genotyping-by-sequencing, resulting in 79,608 high-quality single nucleotide polymorphisms after filtering. A genome-wide association study identified 113 SNPs significantly associated with mineral nutrient concentrations, explaining between 0.4% and 64.3% of the observed variation. Candidate genes linked to these SNPs were found
