An experiment was conducted during rabi 1998 and summer 1999 over tour environments with twenty-one maize genotypes to study the genetic variability and stability for fodder yield and its components in baby corn. Genetic analysis revealed that plant height and fodder yield recorded high genotypic co-efficient of variation, heritability in broad sense and genetic advance indicated that selection based on these characters will result in improving fodder yield. The GXE interaction was highly significant for linear and non-linear portion for days to 50 per cent tasselling, plant height and fodder yield. The stability parameters revealed that JH-3673 and AH-469 exhibited average stability for fodder yield. The genotypes PAC-779 and PRO-324 exhibited above average stability for fodder yield indicated their potentiality to be grown under poor environments.
