Abstract

Genetic variability, correlation and path analysis were studied in a set of sixty diverse genotypes of roselle (Hibiscus sabdariffa L.) dur-ing Kharif, 2013 at Uttar Banga Krishi Viswav-idyalaya, Pundibari, Coochbehar, West Bengal for eleven important traits. Phenotypic as well as genotypic coefficients of variability were high for the important productivity characters like fibre yield plant⁻¹, dry stick weight plant⁻¹ and green weight plant⁻¹ (for PCV) and medium for other characters like plant height, intermodal length and petiole length. High heritability coupled with high expected genetic advance was ob-served for fibre yield plant⁻¹, dry stick weight plant⁻¹ and green weight plant⁻¹. Fibre yield per plant was found to be significantly and positively correlated with all the characters both at pheno-typic and genotypic levels except petiole length which was significantly correlated in negative direction. Plant height, base diameter, mid diam-eter, green weight plant⁻¹ and dry stick weight plant⁻1 also exhibited significant positive inter correlation among themselves. Partitioning of correlation coefficients of various components upon fibre yield plant⁻¹ into direct and indirect contributions revealed that dry stick weight plant⁻¹ has maximum direct effect upon fibre yield plant⁻¹ followed by plant height and mid diameter.
