QUALITY ATTRIBUTES OF TOMATO GENOTYPES UNDER PROTECTED ENVIRONMENTMAMTA, N.S. DHILLON AND G. SINGH
Tomatoes are an important part of a healthy human diet. The productivity and quality of the produce are being measured by using advanced production technologies. Protected cultivation is an advanced agrotechnology that is utilized all over the world to generate high quality output. Indeterminate tomato is a growing crop though, still, in Punjab, no systemic work has been done for the evaluation of quality attributes of indeterminate tomato genotypes under the protected environment. Inherent diversity is a chief concern for the improvement of quality attributes in tomato. Considering the importance of tomatoes, there is an urgent need to screen out genotypes of indeterminate tomato for a best quality production and for higher nutritive value. The investigation was carried out at the Department of Vegetable Science of Agriculture, Khalsa College, Amritsar, Punjab, India and the experiment were conducted under modified naturally ventilated polyhouse following Factorial Randomized Block Design with three replications, consisting twelve genotypes including standard check during spring-summer season, 2020-2021. The data exhibited significant variation in twelve genotypes for different characters. Based on mean performance, the result let out that Punjab Gaurav and JC-165 was superior for all the quality attributes. Whereas, pericarp thickness and fruit shape index were maximum in KCA-2 while Punjab Sartaj was sophisticated for TSS, lycopene and ascorbic acid although greater titrable acidity was recorded in Arka Vikas. Significantly, the result was higher due to the favorable conditions provided in a protected environment during the growing period with the interaction of genes of genotype.
