Abstract

Fourteen chickpea genotypes were evaluated in RCBD with two replications in two separate experiments under moisture stress and non-stress condition to study the physiological indices for drought tolerance. Significant differences exhibited amongst the genotypes for phenology, vegetative growth and source, generative growth and sink capacity, physiological parameters and drought characteristics under moisture stress and non-stress conditions. The genotypes, Phule G 09103, Phule G 2008-74, Digiijay, Phule G 0302-26 recorded minimum percent reduction in yield due to moisture stress. RLWC, membrane injury index, chlorophyll content, chlorophyll stability index, proline accumulation and nitrate reductase activity were found to be the most useful parameters while selecting genotypes for drought tolerance. The genotypes, Phule G 07101, Phule G 2008-74, Digvijay, Phule G 0302-26 under irrigated condition whereas, Phule G 09103, Phule G 2008-74, Digvijay, Phule G 0302-26 under moisture stress condition were promising for yield and yield contributing characters. The genotypes Phule G 09103, Phule G 2008-74, Digvijay exhibited higher values for drought tolerance efficiency, proline content, chlorophyll content and lower values for drought susceptibility index, membrane injury index indicating their drought tolerance behavior. Therefore, these genotypes can be used as sources of drought tolerance in further breeding programme for evolving the drought tolerant genotypes in chickpea
