title: Evaluating morpho-physiological and quality traits to compliment seed yield under changing climatic conditions in Brassicas.
abstract: A study was conducted under irrigated conditions to test the performance of improved cultivars of Indian mustard (B. juncea), Gobhi sarson (B. napus) and African sarson (B. carinata) under changing climatic conditions. The effect of cultivar, environment and their interactions were significant in mustard and canola gobhi sarson. Environment had significant impact on all the studied traits except for leaf area index (LAI). Cultivar x Year (G x Y) interaction was significant for flowering behavior, days to maturity, SPAD, photosynthetic active radiations (PAR), growth parameters, yield components and yield except photosynthesis photochemical efficiency, relative water content (RWC) and LAI. Cultivar RLC1 surpassed other B. juncea cultivars for yield and had low erucic acid ('0') while GSL1 (non canola), Hyola PAC401 (hybrid canola) and GSC6 (canola) of B. napus were superior in performance for seed yield and possessed low erucic and glucosinolate content ('00'). Higher seed yield was associated with more number of total siliquae/plant, seed weight, biomass, seeds/siliqua, SPAD and RWC. Correlation coefficient revealed high positive association for seed yield with days to maturity (0.639**), plant height (0.982**), secondary branches (0.826**), total siliquae/plant (0.913**), seed weight (0.761**) andbiomass (0.891**).
