Maize is an important cereal crop after wheat and rice. It is grown on a wide range of
environments across the world. Genotype × environment interaction affects the
relationship between phenotype and genotype of in breeding programmes, particularly
for quantitative traits. So multi environment trials (MET) are used for evaluation and
identification of stable genotypes across the environments. So, to assess the
differential performance of the 18 genotypes, an experiment was conducted under
three different locations and different environments viz., Ludhiana, Godhra and
Varanasi under irrigated, rainfed and drought condition, respectively during kharif
2017. Randomized completely block design (RCBD) along with two replications was
used. Data was recorded for grain yield and then subjected to additive main effects
and multiplicative interaction (AMMI) analysis to understand the interactions
between genotypes and environment and identify the stable genotypes. In AMMI1
biplot the PC1 explained 65.07 percent of the variation. Genotypes ZH 161434 and
ZH 161311 with high mean yield and wider adaptability were found stable across the
environments. Genotypes ZH 161038 and ZH 161083 were best performing
genotypes under irrigated environment at Ludhiana, whereas under rainfed conditions
at Godhra, ZH 161434 and ZH 161093 revealed good grain yield. Genotype ZH
161063 was specifically adapted under drought conditions at Varanasi. The best
selected genotypes having wider adaptability across the environments can be used
further in the breeding programmes.
