Abstract

The present investigation was planned to estimate the variances between genotype and within genotype, to estimate genetic parameters and to identify superior genotype for further utilization at Department of Vegetable Sciences, Horticultural Research cum Instructional Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh during Rabi season 2019-2020. Here fifteen tomato genotypes were evaluated in randomized block design with three replications. Based on analysis of variance along with genetic parameters viz., range, means, GCV, PCV, heritability and genetic advance significant differences were observed for all twenty characters. On mean performance of tomato genotypes, it was found that the genotype 2019/TODVAR-9 followed by 2019/TODVAR-8 and Pant Tomato 3 recorded significantly higher yield per hectare and were most suitable for Raipur region. For all the parameters, PCV estimates were greater than GCV indicated that environmental factors stimulating the expression of all

Conclusion

In the present investigation most of the parameters showed significant mean sum of square except TSS content, which indicated that sufficient amount of variability is present among different genotypes. Based on mean performance of tomato genotypes it were found that the genotype 2019/TODVAR-9 followed by 2019/ TODVAR-8 and Pant Tomato 3 recorded significantly higher yield per hectare and were most suitable for Raipur region. For all the parameters the PCV estimates was greater than GCV indicated that environmental factors stimulating the expression of all parameters. Occurrence of high heritability as well as genetic gain was recorded for the traits secondary branches, days to first flowering, days to first fruiting, days to fruit maturity, fruit weight, polar diameter, equatorial diameter, pericarp thickness, calyx length, acidity and yield per plant. These indicated the influence of additive gene effect in heritability of these parameters. Hence, these traits are important for improv
