Phenotypic Variability and Correlation Between Characters in Seven Forage Sorghum (Sorghum bicolor L. Moench) Genotypes

Abstract

A field experiment was conducted at the Demonstrated Farm, Agricultural Research Corporation Shambat during the season 2015- 2016, to investigate the genetic variability and phenotypic correlation between yield and growth characters in Forage Sorghum (Sorghum bicolor L.) ghenotypes. The experiment was laid in a randomizd complete block design (RCBD) with three replications. Characters studied included: growth attributes (Plant height (cm), stem fresh weight (g), days to maturity, stem dry weight (g) and stem diameter (mm). The results showed that high significant variances were observed for all the studied characters, except stem dry weight, it was non significant. Negative correlation was observed between dry weight and plant height, stem diameter and days to harvest. The genotype Abjaro×Abnaffain gave the highest mean in dry weight.
