Evaluation of pigeonpea genotypes against sterility mosaic disease under artificial inoculation conditions

Seventy four germplasm lines of pigeonpea (Cajanus cajan L. Millsp) were screened against sterility mosaic disease by using infector row and leaf stapling technique. three genotypes viz., BRG 16-1, NTL 30 and ML 31 showed resistant reaction against sterility disease while twelve genotypes viz., BRG 16-2, IcP 7119, ICPL 15084, BDAH 2013–41, BDN 711, PT 711-1-1-2, CO-6, WRG 255, VRG 06–003, NTL 873, MAL 47 and BSMR 736 were found to be moderately resistant on PDI basis while on the basis of AUDPC, four genotypes viz., BRG 16-1, NTL 30, BDAH 2013–41 and ML 31 showed resistant reaction against sterility mosaic disease while twelve genotypes viz., BRG 16-2, ICP 7119, ICPL 15084, ICPL 15036, BDN 711, PT 711-1-1-2, CO-6, WRG 255, VRG 06–003, NTL 873, MAL 47 and BSMR 736 were found to be moderately resistant against sterility mosaic disease. Genotypes found resistant to moderately resistant can be utilized as parents for transferring stable sterility mosaic resistance in varietal breeding programme.
