Abstract

The experiment was conducted with the objective of estimating the genetic variability and the path coefficient analysis for yield and yield related traits of 45 newly released rice genotypes at the research field of Council for Scientific and Industrial Research – Crops Research Institute in Sokwai, Kumasi. The Genotypic Coefficient of Variation (GCV) were lower than the Phenotypic Coefficient of Variation (PCV) for all the traits indicates the influence of environment on the traits. The GCV and PCV value ranged from 0.95% to 12.93% and 2.95% to 78.50%, respectively. Panicle length recorded moderate heritability together with moderate genetic advance which suggests that they can be improved through direct selection due to predominant additive variation and indicating that a moderate level of genetic variability is present in these characters. Positive and direct effect was exhibited by the plant height, tiller number per plant, plot weight before winnowing on the grain yield as important traits to be considered during selection and improvement programmes.
