Abstract
The present investigation entitled “Heterosis, combining ability and evaluation of F1 hybrids of cherry tomato under different growing conditions” was undertaken to develop the cherry tomato hybrids having better yield and quality characters, highly heterotic and highly stabilized under different growing conditions. Seven diverse genotypes and their 21 F1s obtained by half diallel mating system were evaluated during rabi, 2010-11 in a Randomized Block Design with three replications. The data was recorded on yield and quality components. Significant heterosis in favourable direction was recorded for fruits per cluster (25.00 %), clusters per plant (24.91 %), acidity (14.43 %) and lycopene (11.74 %) over better parent, while, polar diameter (-19.96 %), clusters per plant (101.10 %), acidity (13.27 %) and lycopene (-31.31 %) over commercial hybrid by the cross combination EC 128021 x EC 163615, for fruits per cluster (24.07 %), fruit yield (21.91 %), reducing sugars (11.19 %) over better parent, however, clusters per plant (81.87 %) and lycopene (18.11 %) over commercial hybrid by EC 163615 x EC 128618, for fruit yield (41.06 %) and acidity (11.24 %) over better parent, while, clusters per plant (65.93 %) over commercial hybrid by EC 539 x EC 128021.
