Résumé partiel
The present investigation was conducted at ARS, Kalaburgi, University of Agricultural Sciences, Raichur, during the rabi 2018-19. Among two experiments conducted, the first experiment was laid out in split plot design which consists of eight genotypes sown in the field under stress and non stress condition to evaluate morpho-physiological, biochemical and yield parameters, whereas second experiment was conducted for root characterization study of same genotypes in PVC pipes. The effects between stress and genotypes and growth behavior was studied during 20 DAS, 40 DAS, 60 DAS and harvest stage. Significant changes in the plant height, biomass, growth parameters and root traits under both stress and non-stress condition were recorded, indicating the effect of moisture stress on plant. Among the genotypes, TRCRM-141 shows significantly higher plant height, growth parameters such as SLW, CGR, LA and also proline content (5.59 μ mole g-1 fresh wt.), relative water content (76.9%) and least values were recorded in Selection-4 and BGS-9 (check) (4.02 and 4.74 μ mole g-1 fresh wt., 62.9 and 68.2%, respectively) under both stress and non stress conditions
