Drought susceptibility index analysis in Indian mustard (Brassica juncea L.)

Zafar Ali and SK Rai


Climatic variation like drought is a catastrophe in the current era as it has a high level of impingement on the yield of rainfed crops like Brassica juncea. Present investigation was aimed at investigating the effects of drought on seed yield and its allies in a set of 03 testers, 15 lines and 45 hybrids devised from them under two contrasting environments irrigated (E1) and rainfed (E2) in two seasons (2018-19 and 2019-20). Parents RH-761, RB-24, RH-749, RH-1209 and RB 66 and hybrids RH-1209 × RH761, RH-1209 × RB-24, RB-77 × RB-24, RL-1359 × RH749 and RH-1209 × RH749 reflected a good drought susceptibility index value for various yield allied and drought tolerance related traits under consideration. These cultivars could be utilized for the development of drought tolerant cultivars for further breeding programs
