Abstract:
The correlation and path analysis of thirteen quantitative characteristics of fourteen parental lines and two commercial checks of tomato (Solanum lycopersicum L.) had been considered for the study conducted during November 2016 to April 2017 to assess the nature and magnitude of genetic variability. A wide range of variation was noticed among the characters studied. Among the quantitatve character, Plant height, number of branches per plant, number of fruits per plant, average fruit weight and yield per hectare (t), all had a highly significant as well as positive link with yield per plant (kg). In genotypic correlation, among the quantitatve character, yield per plant (kg) possessed highly significant and positive correlation with plant height (0.772), number of branches per plant (0.773), number of fruits per plant (0.999), average fruit weight (0.827), yield per hectare (t) (1.038). However, it showed inversly significant correlation with days to 50% flowering (-0.517), fruit color (-0.393) and days to first harvest (-0.320). In genotypic path analysis, all the characters except plant height, days to 50% flowering, fruit color, brix and titrable acidity recorded positive direct effect on yield.
