Genetic variability, heritability and genetic advance for yield related characters of tossa jute (Corchorus olitorius) genotypes

Abstract

The genetic parameters of variability were studied for seven yield related characters in forty-seven genotypes of tossa jute. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Highly significant genotypic differences were reported for all the characters. The maximum coefficient of range were reported for green weight (g)/plant and stick weight (g)/plant followed by fibre weight (g)/plant, green bark thickness (mm) and core diameter (mm). The phenotypic and genotypic variances were the highest in green weight (g)/plant. The high PCV and GCV values recorded in stick weight (g)/plant. The maximum estimates of broadsense heritability were recorded in stick weight (g)/plant followed by fibre weight (g)/plant, green weight (g)/plant and plant height (m). The result from this study leads to the conclusion that green weight (g)/plant, fibre weight (g)/plant and stick weight (g)/plant should be considered during selections for yield in C. olitorius.
