Abstract:

An experiment was conducted during kharif 2013 and 2014 in North Coastal Zone of Andhra Pradesh at Agricultural Research Station, Ragolu, Srikakulam district to study the genetic parameters like variability, heritability, genetic advance, correlation and path analysis for fibre yield and eleven component traits in a set of 60 genotypes of roselle (Hibiscus sabdariffa L.). Phenotypic as well as genotypic coefficients of variability were high for the important productivity characters like green weight (leafless) plant-1, dry stick weight plant-1 and fibre yield plant-1. High heritability coupled with high expected genetic advance was observed for plant height, green weight plant-1, green weight (leafless) plant-1, dry stick weight plant-1 and fibre yield plant-1. Most of the quantitative traits showed highly significant positive correlation with the dependent variable, fibre yield. Partitioning of correlation coefficients of various components upon fibre yield plant-1 into direct and indirect effects revealed that plant height has maximum direct effect followed by bark thickness and green weight plant-1 at both phenotypic and genotypic levels. These characters therefore serve as a basis of selection for a meaningful crop improvement programme for improving fibre yield in roselle.


Keywords: Character association, Direct and indirect effects, Fibre yield, Genetic variability, Roselle.
