In the present study an attempt has been made to germplasm evaluation in 39 diverse genotypes of tomato at Vegetable Research Farm, Rewa (Madhya Pradesh) during the Rabi session of 2011. Analysis of variance showed significant variation among the genotypes for all evaluated traits. Number of fruits plant−1 showed the highest genotypic and phenotypic variance (1282.0 and 1287.6) whereas test weight showed the lowest (0.03 and 0.08). High genotypic variance was observed for most of the characters indicating more contribution of genetic components for the total variation. Genotypic coefficients of variations (GCV) and phenotypic coefficient of variation (PCV) were highest for average fruit weight (48.85 and 48.87), number of seeds fruit−1 (44.54 and 45.29) whereas the lowest were recorded for days to 50% fruit setting (1.984 and 2.81). Higher GCV and PVC were recorded for most of the characters indicating higher magnitude of variability for these characters. The highest heritability (broad senses) estimates were observed for average fruit weight (99.92) number of secondary branches (99.65%), while the lowest was for the test weight (45.29%). Highest genetic advance as per cent of mean was recorded for average fruit weight (100.59%) and lowest for days to 50% fruit setting (2.89). The exploration of genetic variability in the available germplasm is a prerequisite in a breeding programme for effective selection of superior genotype of tomato.
Thirty nine cultivars were selected for the study of genetic variability, heritability, genetic advance in tomato. Highest phenotypic and genotypic variances were observed number of fruits plant−1.
Maximum heritability and genetic advance was recorded for average fruit weight, number of seeds fruit−1 respectively.
Genotypes VS-404, H-86, MHT-256 and Santury were estimated higher yield performance in central plateau of India.
Genotypes H-86, DT-10, Arka Vikash, GT-2 and Arkha Meghali were observed higher pericarp thickness which is desirable character for transportation and storage life.
