The objective of this study was to assess fifty genotypes of Corchorus olitorius for broad-sense heritability, character association and genetic advance in seven yield related characters. 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 was reported for green weight/plant (0.47) followed by fibre weight/plant (0.46), green bark thickness (0.44), stick weight/plant (0.39) and core diameter (0.39). The phenotypic and genotypic variance was highest in green weight/plant (4203.63 and 4199.07). The high PCV and GCV values recorded in green weight/plant (24.27 and 24.25). The maximum estimates of broad-sense heritability was recorded in green weight /plant (99.89) followed by stick weight/plant (99.77), fibre weight /plant (99.61) and green bark thickness (85.71). Strong significant and positive correlation was reported between plant height and base diameter (0.546); core diameter (0.492) green bark thickness (0.324); green weight/plant (0.363); fibre weight/plant (0.428) and stick weight/plant (0.418). The result from this study leads to the conclusion that Green weight/plant, Fibre weight/plant and Stick weight/plant should be considered during selections for yield in C. olitorius.
