- Abstract
Yield potential of lablab bean is adversely affected by the most significant disease namely Bean common mosaic virus (BCMV). Fifteen genotypes of lablab bean (Lablab purpureus L.) were used for genetic analysis and detection of bc-3 gene conferring resistance to bean common mosaic virus. Thirteen yield contributing traits were evaluated for enumerating genetic variability and trait association. Phenotypic variations were greater than the genotypic variations indicating the existence of environmental effect on trait expression. Five pairs of characters showed significant correlation and path analysis revealed both direct positive and negative effects of the yield contributing traits on seed yield. For detection of bc-3 resistance gene, two SCAR primers ROC11 and SG6 were used. Nine genotypes were produced expected bands for SG6 primer indicating the partial resistance due to presence of recessive bc-3 allele. These results could be helpful for further crop improvement program of lablab bean.
