Micronutrients are essential for human health and crucial for plant survival. Increasing temperature and drought are major abiotic stress which limits the productivity and nutritional quality of wheat. The objective of study is to evaluate effect of heat stress and elevated temperature on micronutrient (Zn, Cu, Fe, and Mn) content in wheat (Triticum aestivum L.) grain. The 18 wheat varieties were accessed and evaluated for variations of micronutrient accumulation in there mature grains under two different environmental conditions. Pot experiments were carried out during rabbi 2011-12 at RAU, Pusa Bihar. Generally, elevation in temperature reduces the accumulation of Zn, Cu, Fe and Mn level in grains but some varieties enhances the accumulation of micronutrients under heat stress condition significantly. The wheat varieties Kauz/AA/Kauz, F5-995, Halnaand MonsAld’s are good accumulator for Zn in grains. The accumulation of Cu was increased in grains of Halna, Kauz/AA/Kauz, and F5-99, whereas, AKAW 4008, Halna, PBW343 Kauz/AA/KauzandRaj 3765has good accumulation property of Fe in there grains. The enhanced Mn accumulation under high temperature was observed in grains of variety AKAW4008, Halna, Kauz/AA/Kauz and F5-995. The wheat variety Kauz/AA/Kauz, F5-995, PBW343, Halna and Raj 3765showed overall better micronutrients accumulation in there grains under stress condition and appeared as potentially important wheat variety to reduce the problem of malnutrition
