Abstract: Studies on harvest index, genetic parameters, variability and correlation among different characters of 23 germplasms along with three control variety of Corchorus capsularis were conducted. The highest plant height (3:37m), base diameter (23: 33mm) and harvest index (32: 79) were found in the control variety VCL-1. Dry weight of leaf (12:45gm), dry weight of stick (64:13gm) and total dry matter were the highest in acc. no. 2271. Genetic variations were observed among the germplasms for plant height, base diameter, total dry matter and harvest index. Higher harvest index was found in the control variety CVL-1. No high yielding germplasm having higher harvest index could be identified from the germplasms studied. For all characters, phenotypic coefficient of variation was higher than genotypic coefficient of variation. Plant height, base diameter and dry weight of bark were positively correlated with harvest index.
