Study on Genetic Variability, Heritability and Genetic Advance in Tomato

Thirteen tomato genotypes were evaluated to estimate variability, heritability and genetic advance in yield and yield contributing characters at AICRP on vegetable crop, M.P.K.V., Rahuri. A high degree of significant variation was observed for all the characters studied except pericarp thickness and number of locules. A highest GCV was observed for fruit yield per plant and PCV for fruit yield per plant and number of locules while lowest GCV was noticed for days to first harvest, days to 50 per cent flowering and pericarp thickness and PCV for days to first harvest and days to 50 per cent flowering. High heritability with high genetic advance as per cent of mean was observed for fruit yield per plant and average fruit weight which could be improved by simple selection.
