Studies in genetic variability of sapota (Acharas sapota L.) germplasm

Abstract

A study was carried out to find out the variability among the 19 sapota genotypes at Department of Fruit Science, Horticultural College and Research Institute, Periyakulam. Observations on various morphological, physiological and biochemical characters were recorded. The results revealed that Genotypic and Phenotypic Coefficients noticed for tree height, stem girth, canopy spread and yield which indicates the variability among the genotypes. The results of the variability and correlation analysis indicated that canopy spread, tree height and stem girth were significant and positively correlated with yield, fruit length, fruit diameter, fruit weight, pulp and number of fruits per shoots. Hence, these characters should be considered for selection of genotypes in further crop improvement programme.
