Evaluation of tomato hybrids for fruit, yield and quality traits under polyhouse conditions
Publication Date : 25/07/2015
Protected cultivation is gaining momentum in India since it offers protection from adverse climate and weather, which ultimately influences the overall productivity and quality of vegetables. 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 investigation was conducted at Department of Olericulture, College of Agriculture, Vellayani, Kerala. Twelve tomato hybrids were obtained from public and private sectors and grown under polyhouse conditions. The analysis of variance revealed significant variation among the hybrids for all the characters. Ample variability was observed for vegetative characters as obvious from the wide range obtained for the different characters. INDAM 9802 was the earliest to flower (26.27 days) among the hybrids. Tomato F1 T30 had the potential of setting maximum fruits per plant (35.66) followed by Tomato F1 Queen (35.55). INDAM 9802 recorded the maximum yield of 1444.40 g followed by Tomato F1 T 30 (1412.22) and have the potential to be cultivated under protected conditions of Kerala. A wide range of variation was observed for the biochemical constituents of the fruits. Polyhouse tomatoes had better colour and appearance than those from the field. It has been observed that polyhouse grown tomatoes have potential for better performance and higher fruit yield than open field conditions.
