With an ever increasing human population and gravity of both biotic and abiotic stress, there is a great necessity to breed crop cultivar for adaptation under these stress situations as well as with good high yield potentials to ensure global food security. The prevailing situation of food grain shortage ac­companied by abrupt price hike has alarmed the crop scientists and physiologists to identify comprehensive and convincing multidisciplinary approach to come up with the sustainable technology that must be validated on in situ farm level condi­tions. To meet this challenge, breeders in collaboration with other scientists are working hard to breed high yielding crop cultivars with significant progress. They have established selection criteria for genetic improvement of crops for yield and stress resistance. However, still there is a great necessity to identify simple selection criteria to make their process much easier (Maiti, 2008)…..
