Abstract:
The current study was carried out at the North Instructional farm of School of Agricultural Sciences, Karunya Institute of Technology and Sciences, Karunya Nagar, Coimbatore during 2020-23 to assess the yield and genetic variability of twenty seven genotypes of tomato (Solanum lycopersicum L.). The genotypes were collected from different parts of the country. The experiment was laid out in RBD with three replications. Based on the mean performance the genotype Kashi Aman was found to have high fruit yield per plant and also had reasonable level of ascorbic acid and lycopene content. The magnitude of phenotypic coefficient of variation was slightly higher that genotypic coefficient of variation for all the traits expect average fruit weight, seed number per fruit, number of locules. Further high estimate of heritability and genetic advance as percent of mean were recorded for average fruit weight, seed number per fruit, yield per plant, number of fruits per cluster, number of fruits per plant, number pf cluster per plant, plant height, seed weight per fruit, fruit breadth, 100 seed weight, fruit length, FSI, pericarp thickness, TSS, number of secondary branches and ascorbic acid content. High heritability and high genetic advance are always preferred for an effective selection and improvement.
