Plant breeders' ultimate goal in a crop improvement program is to generate varieties with high yield potential in order to sustain high agricultural productivity. In addition to great yield potential, a new cultivar should have stable performance and extensive adaptation over a wide range of settings in addition to great yield potential. The presence of genotype by environment interaction (GEI) interactions is of major concern to plant breeders, as large interactions can reduce selection gains and make identifying superior cultivars more difficult. It is also of major concern to crop breeders, as phenotypic responses to changes in the environment differ among genotypes. However, phenotypic response varies by location as it is influenced by biotic and a biotic factors as well as environmental factors. The importance of GEI cannot be overstated. It is critical for lowering genotype mean in various contexts. It is utilized as a test of genotype adaptability to the expression of specific phenotypes in diverse environments, and it is a continuous effort of plant breeders due to environmental variation across different locations and throughout time. The fundamental goal of multi-environment trials is to monitor genotype stability across environments, identify superior genotypes, and determine which location best mimics the target environment for production. GEI is critical for lowering genotype mean in various contexts. It aims to generate varieties that are resilient to climate change pressures and a variety of other stresses tolerance or resistance to key biotic stresses like drought, salinity, etc. as well as biotic ones like diseases and pests while also improving human skills.
