Variability and Phenotypic Correlation in some 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 some yield and growth characters in forage sorghum (Sorghum bicolor L.) genotype. 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 50% flowers and stem dry weight(g). The results showed that hight significant variances all the studied characters. Negative correlation was observed between dry weight and Leaf area, Days to 50% flowers, Leaves weight, Number of leaf. The genotype Abjaro×Abnaffain gave the highest value in dry weight.
