Evaluation of indeterminate tomato hybrids for fruit, yield and quality traits under net house and open field conditions

Abstract

The present investigations were conducted at the vegetable research farm and biochemistry laboratory of Department of Vegetable Crops, Punjab Agricultural University, Ludhiana. Twenty six hybrids of tomato along with Check Naveen were obtained from public and private sectors and grown under net house and open field conditions. These twenty six hybrids of tomato were evaluated for fifteen characters.The analysis of variance showed that genotypes are significantly different in treatments for all character in both the environments except average fruit weight is significantly different in replications in with both environments. The observation recorded for hybrids showed that To ind Hyb/3, TH-12, G-600 were found maximum yielding genotypes under net house. These genotypes yields more because of maximum no. of fruits/ plant were found in these genotypes. It was also observed that genotypes under net house yields more as comparison to open field conditions because of early yield and more number of pickings.The observation recorded for biochemical analysis showed that maximum lycopene content was found in hybrid G-600, in both the environments. Maximum fruit acidity was found in hybrid ARTH-128 and TH-13 in net house in TH-23 in open field conditions. Maximum TSS content was recorded in G-600 in expand net house and Naveen recorded maximum in open field condition. Under net house genotypes performed better than open field condition for yield and biochemical traits because of favourable conditions for proper growth under net house.
