ABSTRACT
Drought is considered as one of the key limiting factor for oil seed production and productivity in Rajasthan. Therefore, the present piece of work was carried out at S.K.N.U. Agriculture College, Jobner (Rajasthan), to examine the effect of drought stress in 10 Indian mustard (Brassica juncea L.) cultivars. Yield and yield attributes were thoroughly investigated in the mustard cultivars under control and water stress condition. Plant height, days to 50 % flowering, number of silique/plant, number of seed/ siliqua, seed yield, biological yield, oil content and oil quality were observed in both with irrigation and drought conditions. Yield and yield attributes were decline in all cultivars under drought condition compare to control. Yield and yield attributes data revealed that under irrigation condition performance of genotype RH-0749 and RH-0406 was better than other selected genotype.RB-50 and RGN-48 maintain higher seed yield and oil quantity under drought situation due to lesser reduction in yield attributes and tolerance mechanism. Therefore, selection of drought tolerance genotype based on yield attributes can significantly enhance yield potential under adverse environmental situations.
Key words: Days to 50% flowering. Drought. Yield attributes .Sliliqua. Drought tolerance
