Identification of anthracnose race 1 resistance loci in lentil by integrating linkage mapping and genome‐wide association study

Abstract Anthracnose, caused byColletotrichum lentis, is a devastating disease of lentil (Lens culinaris Medik.) in western Canada. Growing resistant lentil cultivars is the most cost‐effective and environmentally friendly approach to prevent seed yield losses that can exceed 70%. To identify loci c...
