COMPONENTS OF VARIANCES, GENETIC VARIABILITY, HERITABILITY AND GENETIC ADVANCE AMONG FIFTY INDIGENOUS MAIZE (ZEA MAYS L.) INBRED LINESChethan, K.G. and S. Nataraja
Analysis of variance revealed significant differences for all the characters under study which Showed the presence of sufficient amount of variability offering adequate opportunity for improving the population for these characters. The ranges of mean values revealed sufficient variation for all the traits under study. The phenotypic variances and phenotypic coefficients of variation were slightly higher than the corresponding genotypic variances and genotypic coefficients of variation for all the characters. Traits viz., Ear height and rind weight showed high GCV, PCV. Therefore these traits can be used further in crop improvement program.
