Abstract
The research aimed at understanding the mechanism of drought tolerance in wheat at earty seedling and post-anthesis stages. Under early-stage water stress, contrasting genotypes were identified from a germplasm collection using a stress tolerance index. Transcriptomic analysis of two contrasting genotypes, ABURA and AUS12671, revealed their molecular mechanism of adaptation. For later stage water stress, nature of gene action of a diallel population were analyzed. Finally, C306xDharwar Dry hybrids were used for fast-track development of near-isogenic lines (Nils). These NIL pairs were characterized and can be valuable resources for fine-mapping, and cloning of the gene(s) for drought tolerance in wheat.
