Abstract

Avocado (Persea americana Mill.) commonly known as “Butter Fruit” is an evergreen subtropical fruit tree native to Central America and Mexico. Seventy diverse genotypes of Avocado were selected from the Lower Pulney Hills (Western Ghats) of Tamil Nadu for the current study during October 2019 to September 2021. The study was aimed to evaluate the yield contributing characters of lower Pulney hills of Tamil Nadu The yield correlated characters like Tree age, tree height, tree canopy, trunk circumference, fruit circumference, fruit length, fruit weight, pulp peel ratio and yield were estimated. The phenotypic correlation, as well as their direct and indirect impacts, were assessed in avocado using correlation coefficient analysis to determine the influence of the most parameters to yield. Tree height (0.510), tree canopy (0.410), trunk circumference (0.660), fruit weight (0.771), length of seed cavity (0.505), and fruit circumference (0.353) all had favourable direct effects on yield
