Genetic Variability and Inter-relationship Between Fibre Yield and its Components in Roselle (Hibiscus sabdariffa L.) in Terai zone of West Bengal

Genetic Variability and Inter-relationship Between Fibre Yield and its Components in Roselle (Hibiscus sabdariffa L.) in Terai zone of West Bengal

Genetic variability, correlation and path analysis were studied in a set of sixty diverse genotypes of roselle (Hibiscus sabdariffa L.) during Kharif, 2013 at Uttar Banga Krishi Viswavidyalaya, 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 observed 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 phenotypic and genotypic levels except petiole length which was significantly correlated in negative direction. Plant height, base diameter, mid diameter, 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 . p>
