Summary

Phenotypic, genotypic and environmental correlation coefficients were worked out for different quantitative characters in jute (C. capsularis). The environmental correlation coefficients for all pairs of characters were positive and significant except those with the flowering days which were negative. The coefficient of heritability was maximum for flowering days, while genetic advance was maximum for fibre weight.

Selection based on discriminant functions did not give any advantage over straight selection based on fibre yield only. The discriminant functions based on basal diameter and on plant height and basal diameter which had relative efficiencies of 92.22 and 94.52 per cent. respectively may prove to be of value in selection for high fibre yield when information on fibre yield is not available.
