Genetic analysis of yield and its components in fodder maize

Abstract

Nine fodder maize types were evaluated in a randomized block design with three replications during summer 1992 at the College of Agriculture, Vellayani under the AICRP (Forage Crops). Genetic analysis of fodder yield and its components revealed that plant height and plant population recorded high genotypic coefficient of variation, heritability and genetic advance indicating that selection based on these characters will result in improving fodder yield. Highest genotypic correlation was observed between green and dry fodder yield and also between plant population and dry fodder yield. High heritability and high genetic advance observed for plant height indicate additive gene action and the reliability of this character during selection programmes for improving the yield.
