Maize (Zea mays L.) is one of the most important cereal crops of India in terms of production and consumption. Maize is called as Queen of cereal crops. Currently, it is produced in all the agro-ecological zones of the country. In India, Genotype by Environment interactions (GxE) effects on maize grain yield is usually significant due to the diverse environmental conditions at growing sites. Genotype × environment interactions complicate selection of superior genotypes for narrow and wide adaptation. Hundred and six genotypes were evaluated atfour locations in Uttar Pradesh, India to (i) identify superior and stable genotypes across environments and (ii) assess relationships among test environments. Environment and genotype × environment interactions (GEI) were significant (P < 0•05) for grain yield. Yield of the genotypes across the environments ranged from 6.33(mt/ha) for Bilhaur to 7.87 (mt/ha) for Lucknow with an average of 6.61(mt/ha). AMMI biplot of the Interaction Principal Component Analysis (IPCA) scores visualized 48.5% for IPCA1 and 32.3% for IPCA2 with the genotypes and environments for yield. Genotypes AI-0005, AI-022, AI-028, AI-061 and AI-063 less interacting genotypes with high yield and considered as stable genotypes across environments.

Keywords: AMMI stability, genotype x environment interactions, multiple environments
