Abstract
The present study was conducted on 25 sorghum genotypes grown in Randomized Block Design
during Kharif 2015 to evaluate, categorize and classify them for fodder yield and quality traits.
Observations were recorded on eighteen variables involving morphological, quality. Likewise high
estimates for genetic advance as per cent of mean were recorded for most of characters except NDF,
cellulose and ADF. The mean squares were recorded to be highly significant for all the characters
studied. Phenotypic Coefficient of Variation (PCV) was higher than the Genotypic Coefficient of
Variation (GCV) for all the traits denoting environmental factors influencing their expression to some
degree. Genetic divergence study classified genotypes into six major clusters containing one to seven
genotypes. Cluster I and II had most favourable characters as plant height, number of tillers, stem girth,
green fodder yield, dry fodder yield, crude protein, DDM, IVDMD. Though cluster V had only one
genotype i.e. COFS 29 and CSV 21F were found to be better performers, considering fodder yield
characters, IVDMD and crude protein. Correlation study indicated positive association of fodder yield
with plant height, digestible dry matter, and negative correlation with NDF. IVDMD was found to be
positively correlated with DDM, number of leaves, crude protein and negative with lignin.
