Drought stress is an important environmental stress confining growth and development of crops which limits plant performances and productivity. Water stress during flowering and grain filling stage causes reduction in crop yield up to 90%. Drought is a complex trait at plant level and no single trait or parameter can be used for selection of drought tolerance. The genotypic variability of selective traits has found to be important in crop improvement. To identify maximum number of traits related drought tolerance and drought recovery, we tried to evaluate the fourteen inbred lines of maize in field conditions. The experiment was carried out in split plot design with 2 main plots (stress and non-stress) and 14 sub plots (inbred lines). The analysis of variance reported significant differences among the inbred lines indicating variability of the selected inbred lines. The interaction effects between stress and inbred lines were also significant for all investigated traits.Our results indicate that there is a great opportunity for selection of drought tolerance genotypes which can be further used in hybridization and crop improvement programs.
