Total thirteen black gram genotypes/cultivars (SKNU-13-02, SKNU-13-03, SKNU-13-05, SKNU-11-11, SKNU-12-04, SKNU-12-07, SKNU-12-08, SKNU-15-01, SKNU-15-02, SKNU-15-03, T9, GU 1 and Rajasthan local) were screened for their relative susceptibility against stem fly, Melanagromyza sojae during summer (2017) at Entomological farm, B. A. College of Agriculture, Anand Agricultural University, Anand. SKNU-15-02 (23.88%), SKNU-15-01 (27.50%) and SKNU-12-07 (27.58%) exhibited less infestation of stem fly which reflected on yield and found resistant to stem fly. The genotypes/cultivars SKNU-12-08 (45.43%), SKNU-13-05 (45.47%) and Rajasthan local (50.21%) found moderately resistant. GU 1 (60.21%), SKNU-13-02 (65.90%), SKNU-12-04 (66.26%), T9 (67.05%) and SKNU-15-03 (68.86%) categorised as moderately susceptible, whereas SKNU-11-11 (71.02%) and SKNU-13-03 (71.04%) categorized as susceptible against stem fly. Maximum seed yield was obtained from the cultivar Rajasthan local (775 kg/ha) followed by SKNU 15-02 (767 kg/ha) and SKNU-12-07 (741 kg/ha).
