Path analysis of metric traits in Acacia catechu Willd.

Correlation and path-coefficient analysis was conducted on eight characters of Acacia catechu Willd. seedlings for higher shoot dry weight. Phenotypic correlation of shoot dry weight was positive and significant with all other component characters. The genotypic correlation coefficients were positive, significant and greater in magnitude than the phenotypic correlations. Path-coefficient analysis revealed that shoot fresh weight, root dry weight, number of leaves and leaf area comprehend direct effect on shoot dry weight. Therefore, these traits should be given greater importance while formulating selection indices for better establishment of seedling growth in the plantation areas.
