Selection Indices in Roselle (Hibiscus Sabdariffa L.)

Selection indices were constructed using 45 genotypes of roselle (Hibiscus sabdariffa L.). Four characters, viz., plant height, basal diameter, fibre weight/plant and fibre-wood ratio were considered for the formation of selection indices for fibre yield in rosette. The results indicated that all the four characters exhibited high genetic advance and are useful for simultaneous improvement of these characters. Efficiency of fibre-wood ratio was more as compared to the efficiency of fibre weight, suggesting that fibre-wood ratio is an important trait to be considered while making selection for fibre yield in roselle.
