ABSTRACT
A study was carried out with 33 Kenaf (Hibiscus cannabinus L.) genotypes of diverse origin to obtain information on genetic variability, heritability and correlation between fibre yield and various yield attributes. A substantial variability was observed among the genotypes for all 8 characters studied. The character dry stick weight per plant exhibited the highest phenotypic and genotypic coefficients of variation (20.30, 14.11) followed by dry fibre yield per plant (18.06, 12.05) and green weight per plant (17.25, 11.41). Heritability ranged from 98.36 for days to 50% flowering to 15.97% for node number per plant. High heritability coupled with high genetic advance was observed for days to 50% flowering and green weight per plant suggesting the dominant role of additive gene effects in the expression of these two characters. Correlation studies revealed that fibre yield was positively and significantly correlated with all the characters studied except node number per plant and days to 50% flowering. The character node number per plant was negatively associated with fibre yield. To enhance yield status of kenaf, the characters plant height, base diameter, green weight and stick weight could be used as selection criteria.
