Development of F1 hybrids of tomato (Solanum lycopersicum L.) for protected cultivation

Abstract

The present studies were carried out under Naturally Ventilated Polytunnel at Centre of Excellence on Protected Cultivation and Precision Farming, Department of Vegetable Science, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh. The experimental material for the present study comprised of a set of 6x6 diallel crosses of tomato excluding reciprocals were evaluated along with their six parents during the year 2017-18. The observations were recorded on days to 50 percent flowering (days), days to marketable maturity (days), number of flowers per cluster, number of fruits per cluster, fruit length (cm), fruit diameter (cm), average fruit weight (g), number of fruits per plant and yield per plant (kg). Experimental outcome revealed that on the basis of heterosis (better parent) F1 TOINDVAR-1 x TOINDVAR-5 was found best for earliness and hybrid TOINDVAR-2 x TOINDVAR-4 for yield per plant.
