In this study ninety-nine common bean accessions comprising of 65 indigenous and 35 exotic lines were evaluated against four races of Colletotrichum lindemuthianum (03, 515, 598 and 529) prevalent in three common bean producing district of Himachal Pradesh. Out of 99 genotypes, 7 indigenous (IC-288280, IC-296478, IC-448888, IC-313194, IC-278723, IC-319423, and IC-398487) and 3 exotic lines (EC-169813, EC-398530, EC-500226) were resistant to all the four races, whereas 13 accessions were susceptible. The resistant genotypes also exhibited resistance under field conditions at MAREC, Sangla, Kinnaur, a hot spot for the disease. The maximum resistance was found against race 3 followed by 515 and 598, whereas 529 was most virulent. However, race specific resistance was observed in number of accessions. The sources of resistance identified in this study could serve as resistance donor in breeding for anthracnose resistance or subjected to selection procedure of varietal development for direct use by the farmers.
