Abstract:

Studies were planned to analyze the response of chickpea genotypes to water stress (10% - PEG) at germination stage. Four genotypes viz, CM-2000, CM-94/99, CM-98 and 6153 were used and data for root length and protein mobilization from cotyledons to seedlings were collected on fifth and seventh day after germination. Analysis of variance revealed highly significant differences among varieties under control and stressed conditions. CM-94/99 showed significant increase (pst till 7th day. Quantitative decrease in some high molecular weight proteins was observed at 5th day while some new germination related proteins appeared on 7th day in controlled samples of all genotypes. However genotype specific variations were observed under the applied stress. In CM- 2000 delayed expression (on 7th day) of 100 kDa and 60.8 kDa proteins was observed under water stress while these proteins were expressed earlier (on 5th day) in CM-94/99. Moreover expression of 39.6 kDa and 42 kDa proteins was also delayed (7th day) in CM-2000 but no change in the expression of these proteins was observed in other genotypes.
