Abstract

The experiment was conducted to screen a set of 100 genotypes of pigeonpea (Cajanus cajan L.) for resistance to Fusarium wilt and sterility mosaic disease during 2021-2022 using root dip technique and the leaf stapling method, respectively. Based on percent disease incidence of Fusarium, seven genotypes were classified as resistant. Seventeen genotypes showed resistant reaction against sterility mosaic disease. Combined resistance for both diseases was recorded in six genotypes namely, ICPL 15023, ICPL 15063, ICPL 19467, ICPL 19482, ICPL 19489, and ICPL 19499. These resistant lines can be utilized directly as useful donor source in pigeonpea hybridization programs to improve resistance.
