| Abstract/Description: | Drought stress is the major environmental constraint contributing to grain yield instability of wheat. In the present study, the recombinant inbred line population derived from DBW43/HI1500 cross was characterized for various morpho-physiological traits as well as grain yield stability analysis under moisture stress. The population was evaluated for grain yield under three different moisture stress environments viz., restricted irrigation, rainfed and late sown rainfed during the cropping season of year 2013–2014. Based on principal component analysis, the first five components explained over 60.40% of genetic variation. Grain yield per plot showed significant correlation with biomass and physiological traits viz., NDVI3, NDVI4, NDVI5, CT1, CT2 and CT3. The combined analysis of variance on grain yield data showed that mean squares of environments, genotypes and GEI were highly significant (p\ 0.01). To determine effects of GEI on grain yield, data were subjected to AMMI and GGE biplot analysis, which identified G4, G69, G28, G67, G55 and G112 as the most stable and high yielding genotypes. Hence, the physiological traits NDVI and CT can be effectively used to screen out the line for drought tolerance. In addition, the stable wheat genotypes identified could be used in future wheat breeding programme. |
