Characterization of wheat genotypes for drought tolerance and water use efficiency

Black locust (Robinia pseudoacaciaL.) is a drought-tolerant fast growing tree, which could be an alternative to the more common tree species used in short-rotation coppice on marginal land. The plasticity of black locust in the form of ecophysiological and morphological adaptations to drought is an important precondition for its successful growth in such areas. However, adaptation to drought stress is detrimental to primary production. Furthermore, the soil water availability condition of the initial stage of development may have an impact on the tree resilience. We aimed to investigate the effect of drought stress applied during the resprouting on the drought tolerance of the plant, by examining the black locust growth patterns. We exposed young trees in lysimeters to different cycles of drought. The drought memory affected the plant growth performance and its drought tolerance: the plants resprouting under drought conditions were more drought tolerant than the well-watered ones. Black locust tolerates drastic soil water availability variations without altering its water use efficiency (2.57 g L−1), evaluated under drought stress. Due to its constant water use efficiency and the high phenotypic plasticity, black locust could become an important species to be cultivated on marginal land.

Wheat crop in developing world including Nepal is grown under rainfed condition and thus face moisture stress at one or more growth stages limiting grain yield. An experiment was conducted at Greenhouse to screen the 60 different genotypes of wheat including Nepalese landraces, commercial cultivars CIMMYT derived advanced lines, NWRP derived advanced lines, and three international drought tolerant check cultivars. The wheat genotypes were grown in pots (single plant) arranged in a replicated split plot design under two contrasting moisture regimes, optimum and moisture stressed. The genotypes were evaluated for water use, water use efficiency, plant height, number of tillers and biomass production. The analysis revealed significant variance between environments and among the wheat genotypes for most of these traits. A wide range of variability was observed for water use, water use efficiency, days to anthesis, plant height, number of tillers and biomass yield in both moisture stressed and non stressed environments. Gautam showed superiority than Bhrikuti and Vijaya among Nepalese cultivar for drought adaptive physiological traits. Landrace NPGR 7504 showed high level of water use efficiency and other positive traits for drought adaptation.
