Resistance to anthracnose caused by races 1 and 2 of Colletotrichum trifolii in selected alfalfa cultivars and annual and perennial Medicago spp



Resistance to anthracnose caused by races 1 and 2 of Colletotrichum trifolii in selected alfalfa cultivars and annual and perennial Medicago spp



Agronomy Abstracts: 54



Of 34 cultivars designated resistant, 11 showed >20% resistance to race 1, seven showed >40% and three >60%. Of the eleven, eight also showed >10% resistance to race 2, Saranac AR showed 53% and Aquarius 72%. All cultivars resistant to race 2 were resistant to race 1. Of 24 annual Medicago spp., 10 had >40% resistance to race 1; eight of these had >40% resistance to race 2. Four annuals with low resistance to race 1 had >45% resistance to race 2.
