Abstract:
Wheat (Triticum aestivum L.) has been defined as the ‘King of cereals’ because of the acreage it occupies, high productivity and the prominent position it holds in the international food grain trade. It is an important human food crop, ranks on top three cereals in the world because of its adaptability, nutritional value and high yield potential which is mainly used for bread and biscuits purpose satisfying hunger globally. High temperature and drought are major abiotic stresses which affects the yield of wheat. For development of stable varieties having consistent performance in all the environments, there must be a presence of large genetic diversity in populations under study. From such populations one can identify genotypes showing wide stability under different environmental conditions. This is performed by understanding the interaction of genotype to the environment. Genotype × Environment Interaction (GEI) is a phenomenon related to the inconsistent performance under diverse environmental conditions and it plays an important role in performance of genotypes under different environment. To reveal patterns of GxE Interaction several methods such as Stability Factor, regression-based approach (Perkins & Jinks, 1968; Eberhart and Russell, 1966; Finlay & Wilkinson, 1963; Freeman and Perkins, 1971), AMMI model (Gauch, 1988) and GGE biplot analysis have been developed. So for the breeders to develop a variety suitable for different environments, the analysis of stability of genotypes is the most important tool.
