The cultivars developed under the present climate should be free from climate change. Of course they can be affected by the climate variability and heat stress.

The first thing is to ascertain how climate has changed, then investigate how wheat is responding to the changes vis-à-vis the ideal growth condition for the wheat. A good example is to note the occurrence of extreme climate events and assess how they are affecting wheat growth and performance.
May be true but my concern is that the climate change is a gradual phenomena and crops like any other living being must become adapted to the change which has occurred in the past and therefore it is the heat shock which are more detrimental than the gradually occurring phenomenon called climate change.
Can the wheat crop be grown in some controlled environmental conditions of manually increased or decreased climatic parameters like Temperature or Relative humidity
just like growing crops in the facilities like Open top chambers which are widely used to study the effects of elevated CO2 and other atmospheric gases on vegetation ?
I think it Might be possible, as it would cost much if we have to reduce the temperature, but we can increase the temperature {keeping in view that temperature is apparently increasing (both maximum and minimum) as the climate is changing} with little modifications, but the degree of rise in temperature needs to be controlled.
