Popis: The present study was carried out to identify stable Maize hybrids across various environments as the performance of each hybrid tends to vary when grown in different seasons or locations. Twenty one Maize hybrids and two commercial checks were tested over three locations in India viz., Viluppuram, Trivandrum and Nagercoil. Eberhart and Russell model of stability analysis was carried out which revealed a significant effect of each environment on the hybrids taken, for all the ten morphological traits except the number of leaves. The hybrid AU-101 was identified as a stable hybrid with high mean under less favourable conditions and the hybrid AU-114 was recognized as a stable hybrid under favourable conditions. None of the check hybrids viz., CP-818 and Bioseed-TX369 showed stability in any of the environment. Thus, it emphasized the need for the development of location specific hybrids or a hybrid that is, stable across environments.
