Abstract Pigeonpea genotypes (89) were evaluated for resistance to Pigeonpea sterility mosaic virus Bangalore isolate (PPSMV-B). Of these, three genotypes, ICP 7035, MAL 14 and MAL 19, were found resistant, and two genotypes, ICP 6997 and ICP 8862, were tolerant to PPSMV-B. All the resistant lines tested negative to virus in enzyme-linked immunosorbent assay (ELISA) using PPSMV polyclonal antiserum. The resistant lines can be used in breeding programme for developing PPSMV-resistant high yielding cultivars. Top Keywords Cajanus cajan, host resistance, eriophyid mite, sterility mosaic, PPSMV.
