A field experiment was conducted in Rabi 2015 in a randomized block design with the objective to screen advanced breeding lines (genotypes) of Indian mustard (Brassica juncea L. Czern and Coss) for different physiological parameters viz, chlorophyll content, membrane stability index (MSI %), relative water content (RWC %) and electrolyte leakage and yield related to terminal heat tolerance. The study indicated that genotypes, ‘Pusa Bold’, ‘NRCHB-101’ and ‘PRO-5222’ had tolerance to high temperature at terminal stage. The correlation coefficient between test weight of genotypes and chlorophyll content (), MSI () and RWC () was positive but was negative for electrolyte leakage (- ). |
