Variability, Heritability and Genetic Advance in KenafAccessions (Hibiscus cannabinus L.)

Forty kenaf accessions (Hibiscus cannabinus L.) were evaluated to estimate the variability, heritability and genetic advance in randomized complete block design with three replications. In general phenotypic coefficient of variance (PCV) was higher than that of the genotypiccoefficient of variance (GCV). The highest PCV of 36.50% and GCV of 29.05% were recorded for stem dry matter yield. Broad sense heritability estimates ranged from 14.79% (stem diameter) to 97.26% (days to flowering). The highest expected genetic advance was recorded for stem dry matter yield (47.62%), followed by leaf to stem ratio (43.11%). High heritability and genetic advance for some traits studied indicating that they can be effectively improved through selection
