TAILIEUCHUNG - Biochemical responses of Indian mustard to water stress

Water stress was imposed on four varieties of Indian mustard viz., PusaBahar, Varuna, Pusa Jai Kisan and PusaAgraniby withholding irrigation at 3 different stages of crop growth ., vegetative, reproductive and pod-filling stage. The maximum impact of water stress on total chlorophyll content was observed at pod filling stage. The total chlorophyll content decreased a maximum in cv. PusaAgrani and minimum in Pua Jai Kisan. Proline accumulation increased in all the test verities and maximum accumulation was observed at reproductive stage. Cultivar Varuna registered the maximum proline accumulation. Total chlorophyll and proline content can be considered as the desirable traits for screening the cultivars for drought prone environments. | 2019 8 2 1711-1718 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 02 2019 Journal homepage http Original Research Article https Biochemical Responses of Indian Mustard to Water Stress Chitta Ranjan Sahoo1 Manasi Dash2 and N.

Introduction Water stress during the crop ontogeny has been one of the main constraints for sustainable mustard productivity especially in rainfed mustard growing tracts. Crop losses vary depending upon the genotype physiology intensity and duration of the stress. Improvement of the crop to water stress resistance through plant breeding is the best alternative. Cultivars with better ability to access soil water and improved water use efficiency could increase yield in
