Character Association and Path Analysis for Fibre Yield and Component Characters in Roselle (Hibiscus sabdariffa L.)

摘要

Roselle is an important fibre yielding crop in India next to jute and the fibre is extracted from the bast region of stem. Fibre yield by itself may not be the best criterion for selection as it is quantitatively inherited and influenced by genetic factors as well as environments. The correlation and path analysis provides information about the association between two characters and partitioning of the relationship into direct and indirect effects showing the relative contribution of each of the causal factors towards the yield. In these regards, a good number of research works in jute has been reported by many workers (Ahmed et al., 1994; Chaudhury et al, 1981). The objective of the work was to investigate correlations of fibre yield components andto find out the extent of direct and indirect effects of the components towards fibre yield. Knowledge of these correlations may help in planning efficient breeding programme (Johnson et al, 1955).
