Abstract:
The present study was carried out to investigate yield and quality traits in tomato, in order to generate information regarding the extent of genetic variability, heritability and genetic gain. The experiment was laid out during kharif 2021-2022 in augmented design at Department of Vegetable Science, K.R.C.C.H., Arabhavi Belagavi. Genetic variability was estimated among 220 developed recombinant inbred lines derived from FBT-27 × Sankranti cross of tomato. Analysis of variation revealed that there is a significant difference between all the traits and the magnitude of phenotypic coefficient of variation was slightly higher than the genotypic coefficient of variation for all the studied traits. Further, high estimates of heritability and genetic gain were recorded for all the characters except the quality traits TSS and pH. Thereby, suggesting that straight selection for these traits may bring worthwhile improvement in identifying superior genotypes in tomato.
