Abstract
The present investigation entitled “Performance of tomato (Solanum lycopersicum L.) genotypes for yield and quality trait under Chhattisgarh plains” was carried out in the field of AICRP on vegetables crops, Horticultural Research cum Instructional Farm, Department of Vegetable Science, IGKV, Raipur (C. G.), during the rabi season 2019-20 to study mean performance, genetic variability, heritability, genetic advance, association and path analysis in various characters in tomato genotypes and to identify best genotype suitable for Chhattisgarh plains among them.
The experimental materials comprised of twenty two tomato genotypes and laid out in randomized block design (RBD) with three replications. The analysis of variance showed that the most of the characters studied under the current experiment exhibited significant mean sum of squares due to treatment (genotypes) except only specific gravity. From the mean performance of tomato genotypes it was found that the genotype 2019/TODVAR-5 and genotype 2019/TODVAR-4 were the most promising in terms of yield per hectare (q).
For all the characters studied in present investigation, the magnitude of PCV was greater than the concurrent GCV. Higher broad sense heritability with high magnitude of genetic advance was observed for the various traits viz. weight of fruit, volume of fruit, number of locules per fruit, days to first flowering, number of branches per plant.
Association study among different characters found that the traits viz. number of fruits per plant, weight of fruit, number of flowers per cluster have preponderated effect on fruit yield per plant. From path analysis the traits volume of fruit, number of fruits per plant, weight of fruit, days to first flowering, specific gravity, number of fruits per cluster, fruit diameter and number of locules per fruit showed positive direct effect to the fruit yield. The attributes mentioned above are found as superior yield components.
