ESTIMATES OF GENETIC PARAMETERS AND CORRELATION COEFFICIENTS IN FODDER SORGHUM

Abstract

A wide range of variation was observed for all the twelve characters in 30 genotypes of fodder sorghum and it was more pronounced in plant stand, plant height, leaf length and earhead weight. Further, plant height, plant stand, total, soluble solids and leaf length showed large genotypic variability. Highest genotypic coefficient of variation was observed for fodder yield, followed by total soluble solids and grain yield. Total soluble solids, grain yield, plant height, number of leaves, earhead girth and leaf width had high heritability estimates combined with high genetic advance. Fodder yield had high genetic advance but moderate heritability. The genotypic correlation coefficients were larger than phenotypic correlation coefficients. Plant height and total soluble solids showed high positive correlation with fodder yield. Plant height was by itself correlated with plant stand, leaf length, leaf width and grain yield and this character would be an ideal selection criterion in fodder sorghum.
