Screening of common bean (Phaseolus vulgaris L.) germplasm against Colletotrichum lindemuthianum inciting bean anthracnose

Abstract

Common bean is the most cultivated grain legume consumed globally. It is enriched in proteins, vitamins, minerals and fiber. Anthracnose disease incited by hemibiotrophic fungi Colletotrichum lindemuthianum is the most destructive disease of common beans. The present study was carried out to evaluate 87 common bean genotypes collected from different locations against C. lindemuthianum. Screening of genotypes for anthracnose resistance aids in the identification of 22 highly resistant genotypes namely PL 1, EC-400397, Hur 137, IC-199277, IC-258273, S 2, EC-400442, KB 4, Utkarsh, Hur 15, IC-260299, PDR 14, VL 125, Amber, Arun, EC-398591, EC-121013, S 6, BR 31, IC- 328372, KB 12 and KB 6. These genotypes can act as potential donors of the resistant genes in markerassisted selection (MAS) programmes for transferring the anthracnose resistance gene(s) into the susceptible genotypes.
