Abstract:
The present study was conducted with the objective to assess the extent of variability among the genotypes of tomato. The experimental material comprising forty six genotypes were evaluated during Rabi season of 2014-15. The experiment was conducted in randomized complete block design with three replications and observations were recorded on yield and quality attributes. The analysis of variance revealed that wide ranges of variation were found among the genotypes for all the traits. The estimates of phenotypic coefficients of variation (PCV) were higher than genotypic coefficients of variation (GCV) for all the characters. The estimates of high PCV as well as GCV were observed for number of locules per fruit (25.27 and 24.42) and plant height (21.12 and 20.66), while the high PCV (20.33) was noted for Pericarp thickness. High heritability coupled with high genetic advance in percent of mean was estimated for plant height (95.69 and 41.64), number of locules per fruit (78.67 and 40.96), primary branches per plant (80.67 and 29.73), number of fruits per plant (89.51 and 23.50) and fruit circumference (82.37 and 22.63), which showed ample scope of improvement in these traits through selection.
