Study on Genetic Variability, Heritability, Genetic Advance in Tomato (Solanum lycopersicum L.)

An experiment was conducted to evaluation of genetic variability present in the twenty genotypes and observations were recorded on various yield and yield contributing characters. Analysis of variance showed the significant variability for all the studied characters. High values of GCV and PCV were observed for characters viz., number of fruits per plant (55.74, 56.21), number of locules per fruit (36.44, 37.15), average fruit weight (35.45, 35.97) fruit yield per plant (31.09,32.35) marketable fruit yield per plot (31.10, 32.36) and which indicates the presence of high genetic variation. High heritability coupled with high genetic advance observed for the traits viz., plant height, number of flowers per cluster, number of fruit set per cluster, average fruit weight, number of fruits per plant, fruit yield per plant, fruit yield per plot, fruit shape index, TSS0Brix, Ascorbic acid, Beta carotene, Pericarp thickness, Number of locules per fruit. Which indicates presence of additive gene action and demands for population improvement by selection
