ESTIMATES OF GENETIC VARIABILITY, HERITABILITY AND GENETIC ADVANCE FOR YIELD AND YIELD COMPONENT TRAITS IN THERMO TOLERANT TOMATO (Solanum lycopersicum L.) GENOTYPES
Journal Title: International Journal of Agriculture Sciences - Year 2017, Vol 9, Issue 2
Abstract
Twenty one diverse thermo tolerant tomato genotypes were evaluated to estimate variability, heritability and genetic advance over mean for fruit yield and component characters. Analysis of variance revealed highly significant mean sum of square due to treatment for all the traits suggested thereby the substantial amount of genetic variability was existed in the material under study. Phenotypic coefficient of variation (PCV) was higher than the corresponding genotypic coefficient of variation (GCV) in all the morphological traits under study and the GCV was very close to PCV for most of the characters indicating a highly significant effect of genotype on phenotypic expression indicating ample scope for selection of genotypes from available germplasm for these traits. High heritability in combination with high genetic advance as per cent over mean was recorded in yield per plant, fruit pericarp thickness and fruit equatorial diameter explaining that these characters are governed by additive gene action which is crucial in selection.
