STABILITY OF FODDER YIELD IN VARIOUS TYPES OF MAIZE (ZEA-MAYS) UNDER RAIN-FED CONDITIONS

An experiment was conducted during rainy season of 1991-94 at Hyderaba d on 8 genotypes of maize (Zea mays L.) for their stability in fodder yield. The genotypes (G) in and environment (E) varied significantly, the latter in a linear manner. The G x E interaction was highly signif icant for the linear portion as well as the non-linear portion but wit h a pre-dominance of the former indicating that the genotypes responde d in a linear manner with some of these having non-predictable nature. The high-yielding genotype 'African Tall' was found to be better adap table to good or favourable environments, while 'Varun' (a synthetic) to poorer environment. The double-cross hybrid 'DHM 105' was found to be stable over both poor and better environment having general adaptab ility.
