Abstract

Conventional methods of plant breeding and agronomic practices remained a successful tool to maintain the pace of food production for centuries but due to changing climatic conditions and the challenges of 21st century like population growth, pollution, declining biodiversity and food security have shaken the previous policies. This situation compelled the agriculturist towards the judicious management of natural resources to combat the poverty, disasters and increased food demands. The present study was initiated to check wheat varieties in two water provision conditions. The results revealed that environmental stresses played negative role by minimizing the yield and yield contributing traits. However the severity of water stress was depleted by some promising genotypes by showing minimum hazard effects and by having capability to contribute to conserving biodiversity, ensuring sustainability, combating food insecurity and increasing economic benefits. The minimum effect of moisture stress on grain yield was shown by genotypes C-518 (12.97%) while the genotype Shakar, Pari-73 and Uqab-2000 showed maximum decline percentage. The global warming and population explosion will further induce commodity shortage and law and order situation in the world. The prevailing International tension can be cooled down by the provision of marshal aids by the developed countries to the effected or threatened countries.
