WATER STRESS TOLERANCE AT THE REPRODUCTIVE PHASE IN SELECTED LENTIL GENOTYPES
Lentil (Lens esculenta Medik.) is an important pulse crop with high protein content, has the potential capacity to combat nutritional deficiencies in developing countries. An experiment was carried out with six mutants viz., LMI-3, LMM-4, LMM-5 LMM-6, LMM-7, LMM-9 and a check variety (Binamasur-8) of lentil at the pot-yard of Bangladesh Institute of Nuclear Agriculture, Mymensingh during November 2020-March 2021. Seedling were grown in plastic pot filled with field soil and three water stress treatments viz. control, 45 and 30% FC were imposed at flowering stage and continued up to maturity. The experiment was laid out following a completely randomized design with three replications. Data on morpho-physiological attributes viz., plant height, number of branches plant-1, total dry matter plant-1, harvest index, yield and yield attributes were recorded. Results revealed that almost all the traits decreased significantly in response to water stress. The mutants LMM-7 and LMM-4 were considered as water stress tolerant as they showed better yield performance under stress.
