Abstract
Wheat is one of the most important seed yield crops of the world providing caloric needs to 30 percent world population. The grain yield in wheat is interactively determined by number of tillers per plant, number of grains per year and grain wheat. The grain development in wheat is optimal around mean temperature ranging between 22°C to 25°C (Average temperature). However, in Haryana, Punjab and Indo-gangtic plain zone of Uttar Pradesh, Bihar, the day and night temperatures have a reason due to global climate change causing terminal heat stress during grain growth. The influence of environment varies with heat varieties and cultural practices. Therefore, a coherent wheat production management strategy is necessary to mitigate the environmental affects during grain growth period. These include scheduling irrigation, for the replication of fertilisers and nutrients, addition of organics for better soil environment favour in water and nutrient dynamics and plant water relations so that grain growth is not adversely affected. These selection of short duration varieties with higher photosynthesis activity and faster translocation of photosynthate to grains sink would be more desirable. Grain growth in wheat needs maintenance of canopy temperature for active photosynthesis. Therefore, wheat varieties with foliage characterized by iron reflectance and appropriate transpiration will be more suitable to cope up with environmental stress and minimize adverse environmental impact.
