|a As pesticides have become heavily relied on for management of insect pests vectoring economically important pathogens of vegetable crops, development of pathogen-resistant germplasm remains a promising alternative to reduce or eliminate costly and timely chemical inputs. Molecular markers can be used to rapidly identify resistant genotypes to aid breeders in advancing germplasm. This study developed two kompetitive allele-specific PCR (KASP) genotyping markers for rapid screening of Pisum sativum genotypes for resistance to Pea seedborne mosaic virus pathotype P1 (PSbMV-P1), the most economically devastating strain worldwide. The KASP markers differentiate two eIF4E PSbMV-P1-resistant allelic variants from susceptible eIF4E variants. A single nucleotide polymorphism (Resistant 1) and a 3-basepair deletion (Resistant 2) present in either of the two resistant alleles were used for marker design. Forty-four P. sativum lines previously characterized for resistance to PSbMV were inoculated with PSbMV-P1 in a greenhouse, observed for visual symptoms, assayed for virus susceptibility by enzyme-linked immunosorbent assay (ELISA), and genotyped by KASP marker analysis. The KASP markers were 100% accurate in characterizing PSbMV-P1-susceptible and PSbMV-P1-resistant genotypes when correlated with the ELISA results. The Resistant 1 marker also correlated with resistance to PSbMV pathotypes P2 and P4 completely, making this marker a new advanced tool for P. sativum breeding programs
