An investigation was carried out to estimate genetic
variability and interrelationship of characters in 225
sorghum germplasm under arid condition. Highly
significant variations were recorded among 225
sorghum germplasm for all the traits studied. The
phenotypic coefficients of variation (PCV) estimates
were higher than the genotypic coefficients of
variation (GCV) estimates for all the traits under
investigation. The combined results for heritability
showed that high estimates of heritability with high
genetic advance and GCV were reported for panicle
length, panicle width, fresh weight per plant and dry
weight per plant indicating that these traits were
under control of additive genetic effects.
The fresh and dry weight per plant was strongly and
positively associated with all the traits, except panicle
width. The path coefficient analysis indicated positive
and significant correlation as well as high, moderate
or low direct effects of dry weight per plant, panicle
length, stem diameter, days to flowering, leaf area,
1000 seed weight and grain yield per plant on fresh
weight per plant. This indicates that effectiveness of
selection for dual purpose sorghum as fodder cum
grain crop could be enhanced by inclusion of leaf
area, stem diameter, number of leaves per plant,
panicle length and 1000 seed weight.
