Wheat is one of the leading cereal crops of the world. Being a staple food in Pakistan
it gains more consideration by the specialists. With the increasing population and
fluctuation in climatic conditions, it requires more attention to save people from hunger.
Drought is one of the yield threatening stress in wheat crop and alarming for food
security. In developing countries where water resources are not satisfied according to
the crop requirement, drought tolerant/resistant genotypes are key to feed people.
Although MAS selection and other advances in molecular breeding are done widely to
compete with such stresses but still it is not contributing efficiently so breeding efforts
should be emphasized to cope with drought stressed areas. Hence, there is a need to do
genetic improvement through advanced breeding efforts and evaluation of best
performing genotypes to get new hybrid/variety by combining their genetic potential in
a proper way. By developing specific crosses and selection through proper breeder’s
eye, genetic variability can be created for best executing genotypes that will also
increase our germplasm. In wheat crop, genetic gain has been successfully brought out
through breeding efforts by the breeders. The present research is done to gain genetic
variability by combining alleles through hybridization and analyze yield contributing
traits under drought stress and normal environment to select the yield boosting
genotypes for this stress. Yield influencing traits are evaluated and ultimately
exploitation of best genotype is done based on difference of performance and
adaptability of genotypes under normal and stressed conditions.
