Six chickpea genotypes were evaluated for growth and yield variation under moisture stress condition during Rabi-2011 and 2012. Separate experiments were conducted under rainout shelter condition for moisture stress, mild stress and non-stress in split plot design with three replications. Observations were recorded on moisture status at 15 days interval. The per cent available moisture content was reduced and severity duration frequency (SDF) was increased with the advancing age of the crop. The initiation of flowering and 50% flowering was unaffected however the maturity period was declined due to moisture stress and mild stress condition in all the genotypes. The genotypes Vijay and Digvijay were earlier, whereas, PG-5 and Chaffa were late for days to initiation of flowering, 50% flowering and maturity under all the conditions. Vijay and Digvijay maintained higher dry matter accumulation in component parts of plant under different growing conditions at various stages of growth. The bold seed size genotypes Digvijay and Vishal and medium bold Vijay were promising in respect of yield and yield contributing characters under different growing conditions. Therefore, these genotypes might be considered as drought tolerant types.
