Abstract

A panel of 25 nutmeg genotypes were evaluated at the Horticulture Research Station, Pechiparai, Kanyakumari district from 2019 to 2022 for the pattern of genetic divergence and relationship among them based on seven morphological traits by cluster and path analysis. Notable difference was observed for yield characteristics of genotypes, in which the genotype MF-4 was observed to record high plant height, stem girth, leaf length and fruit production. Genetic variability analysis revealed that traits such as stem girth, number of fruits and mace yield/tree were found to possess high genotypic coefficient of variation along with high heritability and genetic advance as percent of mean which implied that these traits had higher variability among the studied genotypes. The 25 genotypes were grouped in to four clusters based on cluster analysis. Path analysis revealed that traits such as number of fruits, single fruit weight and plant height had a favourable direct impact on the mace yield. These traits might be used as selection indicators in future breeding programmes.

Keywords: Path analysis, D2 analysis, PCV, GCV.
