Abstract
Tomato is a premier vegetable crop of round the year and one of the prominent eco-industrial crops of India generating sizeable employment. The present study which consisted 10 genotypes was evaluated in randomized block design replicated thrice at Regional Agricultural Research Station-Ujjain during Rabi 2007 to 2008. The variation was maximum (424 to 825 qtl/ha) for fruit yield and minimum for fruit width (4.1 to 5.6 cm). The magnitude of genotypic and phenotypic coefficient of variation was higher for number of leaves (21.2 and 22.3), fruit length (cm) (19.6 and 19.7) and fruit yield (19.6 and 19.6). High values of heritability coupled with high genetic advance were observed for number of leaves at 60 days after transplanting (99.4 and 64.9), and fruit yield (99.9 and 24.7). A positive association of yield per hectare observed with number of leaves at 60 days after transplanting (0.78) followed by number of leaves at 30 days after transplanting (0.68), fruit length (0.66) and plant height (0.51).
Key words: Mean, phenotypic coefficient of variation (PCV), genotypic coefficient of variation (GCV), heritability, genetic breeding, correlation, tomato.
