Abstract:
Tomato fruit is full of health-promoting compounds consisting of minerals and antioxidants including vitamin C and E, lycopene, ß-carotene, lutein and flavonoids such as quercetin. Presently in Pakistan, up till now no detailed evaluation study were done regarding quality parameters of tomato cultivated varieties/germplasm. Therefore to resolve these issues, the research was conducted at research area of Vegetable Department of Barani Agricultural Research Institute Chakwal during 2021-22. The study involved evaluation of various lines of tomato for morphological characteristics and fruit quality parameters. For this purpose, 40 various genotypes were evaluated. Significant variation were observed for plant height, number of leaves, leaf area, number of clusters,number of flowers/cluster, number of fruits/cluster, fruit set percentage, fruit size and weight and minimum days to maturity among different genotypes. Maximum variation were also observed for postharvest studies (fruit firmness, total soluble solids, titratable acidity, ascorbic acid content and total sugars). Among indeterminate type, lines Adv-1202 and Adv-1207 were promising lines while for determinate, LBR4, LBR-9, Nadir, LBR-11, 6232, 07039 and Avinash were the most promising lines and performed very well for those above mentioned parameters and had quite well heat resistance. Thus best performing genotypes under climatic conditions of Pothowar can be used in future breeding programmes as parents for trait specific hybrid development.
