“…Under both the conditions Lok1, PBW175, HD2858, PBW343 showed early heading, while NIAW34, HW2004, WH1182, and WH1098 fasten their growth under drought to indicate the genotypic plasticity. In a similar study, ten wheat genotypes of diverse genetic backgrounds, with popular Indian cultivars, were screened for different morpho-physiological characters under drought conditions and traits, such as plant height, number of productive tillers, days of maturity, length of spikelet, spikelet per spike, seeds per spike, thousand-grain weight and yield per plant, were measured [43]. Along with these, CHL, RWC were also recorded to categorize the genotypes.…”

Drought is one of the major abiotic constraints on wheat yields and also for sustainability of production levels around the world. In the near future, the occurrence likelihood of droughts is predicted to become more common, due to changing climatic conditions, thereby posing a serious threat to the food security system. Heterogeneity, in its time of occurrence and severity levels, is likely to further augment the complexity of drought conditions. Although wheat crop growth has progressively risen to good levels, as evident by notable increases in both area and production, the expected wheat demand for the ever-growing population is quite high. Besides crop yield volatility in the era of climate change and dwindling resources, “trait-based” breeding programs are required, so as to develop high yielding, climate resilient and stable genotypes, at a faster pace. For this to happen, a broad genetic base and wider adaptability to suit varied agro-ecologies would provide enough scope for their quicker spread. The current review places emphasis on making distinct categories of the wheat cultivars/advanced breeding lines, as tolerant, moderately tolerant or susceptible to drought stresses, duly supported by an extensive up-to-date literature base and will be useful for wheat researchers, in order to choose the best potential donors as parents, coupled with the associated traits for the development of drought-tolerant wheat varieties, and also to facilitate molecular studies.
