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 21 st 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 in- creasing 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 warm- ing 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.

The pressure on fundamental natural resources, i.e. land, wa- ter and labor witnessed last century in shrinkage of food, fiber and fuel which will continue in the current century due to burgeoning population [1]. Food security situation in developing countries is crippling persistently due to rough farming, economic, financial and water stresses [2]. Pakistan’s economy is fully dependent on agriculture and depicted itself as the biggest employer. The graph in next page presents twenty most important food and agricultural commodities (ranked by value) pro- duction in Pakistan [3]. Food security exists when all people, at all times, have physical, social and economic access to sufficient, safe and nutritious food which meets peoples dietary needs and food preferences for an active and healthy life [3]. In 1996 the World Food Summit (WFS) set the target of “eradicating hunger in all countries, with an immedi- ate view to reducing the number of undernourished peo- ple to half their present level no later than 2015”. In 2000, the Millennium Declaration (MD) promoted the target to “halve, between 1990 and 2015, the proportion of people who suffer from hunger” [3]. Conventional agriculture techniques remained a suc- cessful tool to maintain the pace of food production for centuries. In Pakistan from its existence most of agricul- tural varietal development work was done to increase yield by the use of minimum water [4,5]. Plant breeder’s inputs to combat the challenges of 21 st century, such as population growth, climate change, pollution, declining bio- iversity, quantity and quality and food security compelled d * Corresponding author.
