Abstract

The experiments were carried out to study the genetic variation in Lehsua (Cordia myxa L.) in Thar desert of Rajasthan, India. The variability parameters were studied for physicochemical characters in 15 provenance of Lehsua. The genetic variation was recorded for fruits per cluster, fruit diameter, pulp:seed ratio, fruit weight and total soluble solids (TSS). Most of the characters especially fruits per cluster, fruit weight, fruit diameter and TSS had high heritability and genetic advance as percentage of mean indicating that these to be more under genetic control. The large extent of variation observed in them can be exploited for genetic improvement of this species. 

Key words: Lehsua, provenances, heritability, genetic advance, phenotypic coefficient of variation, genotypic coefficient of variation.
