The Improvement of Maize (Zea mays L.) for Drought Stress Tolerance

Maize is one of the important cereals in world after rice and wheat. It grown for grain as well fodder tropical, sub-tropical temperate regions World. The reduction maize productivity under drought stress conditions depends on different factors such plant development stage, intensity duration water deficit, varietal sensitivity to stress. Drought major constraints agriculture where limited availability crop irrigation causes a carbon fixation by photosynthetic apparatus that result net yield losses. Plant breeders desire novel more accurate tools fast-track breeding programs required increasing demands food because farmers are facing changing climate which has impacts damages globally. Crop loss, stress, huge impact industry economy. Therefore, prevent economic loss make plants tolerant variety approaches conventional molecular/ genetic engineering being practiced.
