GENETIC VARIABILITY AMONG SORGHUM( Sorghum bicolor L. Moench) ACCESSIONS

Abstract

Sorghum ( materials for the livestock and many agro sorghum genotypes in some research institutes and most of these collections lack inform morphology Nigeria. variation in the available materials and the re Grain yield in sorghum is quantitative in nature and polygenically controlled, effective yield improvement and simultaneous improvement in yield components are imperative. Selection on the basis of grain studies provide the basic information regarding the genetic properties of the population based on which the breeding methods are formulated for further crop improvement breeding, there is the need to study the genetic variability which cannot be easily quantified. Genetic improvement for quantitative traits depends on the nature and amount of variability present in any genetic stock and the ext between yield and its component traits and among the component parameters themselves can improve the efficiency of selection in plant breeding. Therefore, there is the need to charac possible sorghum genotypes available in Nigeria to identify traits for yield against future sorghum improvements for better food production and security
