Genetic Variability Studies Regarding Quantitative and Qualitative Traits in Amaranthus

R. Revanappa, B.B. Madalgeri

Abstract


In an evaluation trial consisting of 40 genotypes collected from Tamilnadu and Karnataka, significant variations were observed. The phenotypic coefficient of variability were higher than Genotypic coefficients of variability for all the characters studied. The genotypes 84 =20 and A104 were found to be better for yield and yield parameters. The PCV and GCV were maximum for leaf; stem ratio, number of leaves and fresh weight of leaves while it was minimum for stem girth. Heritability in broad sense was high for most of the characters studied but genetic advance was high for green yield per plant (61.07%) and other yield parameters. The lowest genetic advance (1.06%) was noticed for total chlorophyl content, which is one of the quality trait.
