Background: Tomato is one of the most important vegetable crop grown in the world. Identification of better genotypes among the existing germplasm leads to the success of breeding programme. Elite genotypes should be known for our trait of interest. Methods: A field experiment was carried out at Vegetable Experimental Field, SKUAST-K, Shalimar, Srinagar during Kharif-2018 in which twenty seven genotypes of tomato (Solanum lycopersicum L.) were evaluated to estimate the performance of genotypes on various quality traits like lycopene content, titrable acidity, ascorbic acid content, total soluble solids and juice to pulp ratio. Result: Analysis of variance revealed significant differences among the genotypes for all the traits under studied. Highest lycopene content was recorded in the genotypes 2015/TODHYB-1, Roma and VRT-19 Whereas highest TSS content was exhibited by Kashi Aman, Roma, Jawahar-99 and Shalimar Hybrid Tomato-1. Highest titrable acidity recorded in Marglobe followed by 2015/TODHYB-4 and Kashi Hemanth. Juice to pulp ratio was highest in the genotypes namely, 2016/TODVAR-5 and Kashi Vishesh. Hence, the best performed genotypes can be used as such in promotion of tomato production programme as elite germplasm lines/varieties or may be recommended for commercial cultivation after testing them over years and locations.

Tomato (Solanum lycopersicum) is an economically important vegetable crop grown in tropical and sub-tropical parts of the world. The objective of this paper is to review nutritional benefits of tomato, its different bioactive components and their application in food products. Tomato and tomato products are very beneficial to our health as they decrease the risk of many diseases, such as cancer, asthma, heart disease etc. The whole fruit of tomato i.e pomace, seed and tomato solids have many nutraceutical benefits and is extensively used in food processing industry either as raw or in powder form. Many bioactive components are present in tomato, such as lycopene, oleoresin, carotenoids etc. Tomato is very popular for high content of antioxidant compounds and antioxidant activity. It is preserved mainly by drying (tray drying, freeze drying) and encapsulation process. We have tried to focus on to get the answer, which one is better in food application, lycopene supplementation or dire...
Evaluation of physico-chemical characterization of tomato (Lycopersicon esculentum Mill.) germplasm
Eleven tomato germplasm (Cherry tomato, Rio Grande, Gala, Kalam, Red Star, Roma VF, Taj, Peshawar Local, Bambino, Roma and Roma King) of edible tomato (Lycopersicon esculentum Mill.) were investigated at The University of Agriculture Peshawar during 2017. The aim of this experiment was to evaluate and select tomato germplasm, which could be grown for raw material production and future breeding, taking into account their nutrition composition. The statistically analyzed data indicated that tomato germplasm were highly significant (P ≥ 0.01) in physical and chemical contributing parameters. Physical and chemical data of different tomato fruits at harvesting stage indicated that maximum fruit weight (81.3g) and highest Ascorbic acid content (14.64 mg 100 g-1) was found in tomato cv. Gala. Maximum fruit firmness (2.07) was observed in variety Roma. Maximum percent juice content (91.8 %) were taken by tomato germplasmKalam. Maximum Total Soluble Solid (TSS) (4.8) was measured in tomato germplasm Bambino, whereas maximum (0.37%) acidity was measured in cv. Rio Grande. Maximum (4.63) fruit pH was recorded in germplasm Roma King, which statistically at par with fruit pH (4.56) observed in tomato variety Bambino. It was established that according to above results the tomato cv. Gala and Rio Grande performed best in physical and chemical contributing parameters for quality attributes. These tomatoes cultivars can be grown for raw material production and may be used in future breeding.

Twenty-two tomato advanced lines were investigated for the functional and antioxidant properties as well as their contents. Wide variations were observed for most of the traits, e.g., total soluble solids (3.50-6.03%), pH (3.90-5.08), pericarp thickness (5.40-8.70mm), fruit firmness (0.418 to 0.959 kg), lycopene content (2.84-9.83 mg/100g fw) and β-Carotene (3.37-8.16 mg/100g FW), indicative of considerable levels of genetic diversity. Highest concentration of ascorbic acid was found in the cultivar VT 1320 (305.59 mg/ kg). Total phenolic content ranged from 0.60 to 1.14 mgGAE/g FW whereas total flavonoids content ranged from 0.99 to 1.75 mgCE/g FW. Total flavonoids, total antioxidant activity, ABTS and DPPH free radical inhibition, total polyphenols and lycopene are having strong positive correlation among themselves. The results of present study are potentially useful for tomato breeders working on the development of new varieties with better quality.

Physicochemical, nutritional, agronomic and sensorial parameters, which define fruit quality of tomato (Solanum lycopersicum), were evaluated in 13 traditional varieties collected from several localities in Tunisia, using three commercial varieties as controls. Several varieties were identified as better score for total solid, soluble solid, sugars/acid ratio and vitamin C concentration than the commercial varieties. These varieties could be a resource of good quality in breeding programmes. The correlation between specific parameter seen in this study showed that the local varieties can be differentiated, not just as a function of their morphological attributes but also as a function of their organoleptic, nutritional and sensorial quality.

Tomato (Solanum lycopersicum) is the globally most consumed vegetable. The objective of this research was to analyze physico-chemical, nutritional and sensorial components (taste and flavor) in two new commercial hybrids (AS 300 F1 and AS 400 F1) and their four F7 parental lines. Two widely grown F1 hybrids (Precos F1 and Addalyn F1) were used as controls. The results obtained for carbohydrates (HPLC-RID) indicated that the highest values (27.82 mg/g) were recorded in the paternal line AS 10 of the new hybrid AS 400 F1. The highest values of total organic acids (HPLC-VWD) were recorded in Addalyn F1 (5.06 m/g), while the highest value of phenolic compounds (HPLC-DAD-ESI⁺) were identified in the maternal line AS 09 of the hybrid AS 400 F1 (96.3 µg/g). Intrinsic sensory values were analyzed by male and female tasters of different ages using a hedonic scale. The tasters’ perception revealed obvious taste differences between tomato genotypes. The study allowed determining genetic parame...

Tomato (Solanum lycopersicum) local varieties are having an increasing demand. We characterized 69 local tomato accessions from eight cultivar groups for proximate composition traits, major sugars, acids and antioxidants. A large diversity was found, with differences among accessions of almost tenfold for lycopene. Significant differences were found among cultivar group means for most traits. The Cherry and Penjar groups generally presented higher dry matter, soluble solids content, titratable acidity, taste index, -carotene, ascorbic acid, total phenolics, and antioxidant activity that the other groups. Wide ranges of variation were found within each cultivar group. Positive correlations were found between proximate traits related to taste and antioxidants. The multivariate principal components analysis confirms the distinct profile of the Cherry and Penjar groups and the large variation within groups. The results will be useful for the differentiation, enhancement and selection of local tomato varieties with improved organoleptic properties and functional quality.
