Twelve genotypes of mungbean were screened for powdery mildew reaction under natural epiphytotic conditions. The genotype ‘TARM-18’ exhibited resistant reaction. Out of twelve genotypes, two were used as lines and the remaining ten as testers. These were crossed in a line × tester fashion to generate 20 hybrids for assessment of heterosis. Moderate to high heterosis was observed for seed yield and its 11 component traits and the maximum heterobeltiosis for early maturity was recorded in ‘Chinamung’ × ‘Meha’ and the highest better parent heterosis for seed yield/plot was reflected by the cross ‘Chinamung’ × ‘VC-1’ (136.4%) followed by ‘Chinamung’ × ‘BPMR-1’ (77.42%) and ‘Chinamung’ × ‘TARM-18’ (66.77%). The highest harvest index (%) was shown by the cross ‘Pusa Baisaki’ × ‘TARM-1’ (34.12%) followed by ‘Pusa Baisaki’ × ‘BPMR-145’ (27.12%).
