The multilocational studies were conducted to evaluate 21 hybrids of tomato in Pratapgarh(Uttar Pradesh), Varanasi (Uttar Pradesh) and Burdwan (West Bengal), India during August–February of 2015–16 and 2016–17. Data on four quality traits viz., total soluble solids, titrable acidity, carotene content and lycopene content were estimated. Combined analysis of variance (ANOVA) revealed significant effects of locations, genotypes, genotype-location interaction and parents vs hybrids-location interaction for all the traits. The significance of combining ability effects (general combining ability and specific combining ability) and their interaction with location revealed environmental influences on combining ability effects for all the traits. The Present study indicated higher estimates of to , lower estimates of heritability and GCA/SCA ratio for quality traitsandthereby implied preponderance of non-additive gene action in determination of quality traits studied. Desirable parental lines were identified for different traits like EC 620438 and BS 24-2 for TSS, BS 24-2 and Superbug for titrable acidity, Columbia, EC 620438 and Superbug for carotene content, and H 86 and EC 620541 for lycopene content. Similarly, desirable specific combiners for different traits were identified. The hybrid combination EC 620438×BS 24-2 appeared good specific combiner for TSS, carotene and lycopene content. The parental lines/hybrids identified in present study will be useful in identifying hybrids adapted to a range of environments.

Result Analysis

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.

Number Of Seeds

Combining ability for yield and nutritional quality traits in tomato were studied by involving 28 cross combi-nations obtained from crossing 8 diverse lines in diallel mating fashion. Based on GCA effects of parents, the varie-ties Pant T-3, Arka Alok and Sel-7 were good general combiners for most of the traits under study. The crosses viz., Pant T-3 x H-24 (1.052%), Arka Meghali x Punjab Chhuhara (0.768%) and H-88-78-1 x Azad T-5 (0.768%) were found to be high positive specific combining ability effect for yield per plant. For quality traits, the crosses Arka Me-ghali x Punjab Chhuhara and H-24 x Sel-7 were also superior specific combiner for number of seeds per fruit and ascorbic acid, while cross Punjab Chhuhara x H-88-78-1 was superior specific combiner for number of seeds per fruit (24.165%), yield per plant (0.677%) and titrable acidity (0.183%). These elite hybrids may be tested for yield and other quality traits under different agro-climatic conditions for commercial exploitation of hybrid vigour.

<p> Five parental forms of tomato (Solanum lycopersicum L.) and twenty hybrids F1, were studied which were obtained by the complete diallel scheme (5 x 5). For genetic analysis (by Hayman, 1954; Jinks,1954) was used line №477 (sp,u), variety Alya (sp) with reduced  duration of vegetation period and three collection samples with the high lycopene content in fruits: Dark Green (hp-2dg), МО 112 (hp), Т˗3627 (Bc). The effects of the general (GCA) and specific combining ability (SCA) of the duration of vegetation period were determined and established character of inheritance. According to the results of research, the duration of vegetation period is controlled by additive-dominant genetic system. Inheritance occurs by type of over dominance, and in dry and hot summers which led to the prolongation of the duration of vegetation period, there is a tendency to incomplete dominance, but it is apocryphal. In genetic control a major role play non-additive effects of genes. The best reliable effects of the general combining ability (GCA) had line №477 and variety Alya. They can be recommended for the creation of heterotic hybrids and varieties.</p>

The objective of this study was to evaluate the effect of substrates formulated with different blends of sand-solarized manure and sand-vermicompost over yield, commercial and phytochemical quality of greenhouse tomatoes, and in addition to determine their benefit-cost (B/C) ratio for organic production of tomato. Six substrates were established consisting in blends of sand with 20, 30 or 40% of solarized manure (SM20, SM30 and SM40), and 20, 30 and 40% of vermicompost (VC20, VC30 and VC40), and control (TA) of sand fertilized with Steiner solution. Fruit yielding, commercial (fruit size, equatorial and longitudinal diameter, firmness, and soluble solids content), and nutraceutical quality (phenolic and lycopene content) were evaluated. In addition, cost-benefit (B/C) ratio of treatments was compared. Micro morphological analysis of the organic materials showed microscopic differences that could affect substrate functional properties. Substrate type affect yielding, and VC40 substrate had a higher yield than SM substrates, but SM20 had the highest phenolic and lycopene content in fruit, in addition to the highest cost-benefit production ratio (2.31). These results confirm that substrates formulated with blends of sand and either SM or VC can be used for organic production of tomato fruits with an adequate commercial and phytochemical quality without affecting yield, additionally to the economic advantages of such substrates for protected agriculture systems.

AbstractAn experiment was carried out to study the effect of post-harvest dipping and various packaging materials on quality traits of mandarin at the laboratory of Project Implementation Unit (Citrus zone) Udayapur, Katari from January to February 2019. The parameters observed were physiological loss in weight, juice content, titrable acidity, total soluble solids, TSS/TA ratio and shelf life. The packaging materials include individual newspaper wrapping, perforated polyethene and corrugated box. Gibberellic acid with a concentration of 100 ppm was used as a dipping material. The experiment was laid out in Completely Randomized Design (CRD) with 8 treatment replicated 3 times. The result showed that among eight treatments combination, fruits treated with GA3 in combination with perforated polyethene recorded minimum physiological loss in weight (1.99%) and control (19.08%). High retention of juice content (40.30%), total soluble solids(12.83 brix) and titrable acidity (0.60%) was recorded in fruits treated with GA3 in combination with perforated polyethene in 24 days of storage. Fruits treated with GA3 in combination with perforated polyethene attained shelf life of 48 days followed by perforated polyethene with a shelf life of 44 days. Finding of the experiment may prove to be helpful in rural area to store mandarin with minimum loss as markets are far from the village.

A study was conducted in tomato using an 6 x 6 diallel crossing design excluding reciprocals to quantify the magnitude of heterosis and to identify the best heterotic combinations for post harvest and nutritional quality attributes viz. pericarp thickness (mm), fruit firmness (g/0.503 cm2), shelf life (days), total soluble solids (oBrix), lycopene content (mg/100g) and ascorbic acid (mg/100g) which are considered essential in present day hybrid varieties of tomato from consumer point of view. All the 22 entries (6 parents, 15 F1 hybrids and 1 standard check) were field evaluated using randomized complete block design with three replications during Kharif 2015-16. Highly significant heterosis (5% level of significance) of positive nature was found for pericarp thickness (22.90%, 32.20% and 5.62%), fruit firmness (17.32%, 56.72% and 9.21%), shelf life (17.54%, 24.87% and 9.57%), total soluble solids (24.44%, 51.44% and 34.20%), lycopene content (28.75%, 35.05% and 25.63%) and ascorbic acid (19.07%,30.00% and 17.85%) over the better, mid and standard check, respectively. Three promising crosses viz., Solan Lalima x EC-1055, Solan Lalima x EC-1057 and Solan Lalima x EC-1058 were identified as high yielding F1 combinations having superiority to post harvest and nutritional quality traits in tomato and can be promoted for release and commercial cultivation.

While processing tomato cultivation (Solanum lycopersicum L.) is considered one of the most important industrial crops in Greece, a waste known as tomato pomace is growing significantly high. Notably, the tomato pomace presents enormous opportunities for the creations of organic fertilizers. The aim of this study was to investigate the use of tomato pomace as a fertilizer in the same crop. A field experiment was established at the Agricultural University of Athens during 2018 and 2019 in a randomized complete design with five treatments (control, inorganic NPK (NPK), Tomato pomace and Biocycle Humus Soil (Tp and BHS), Tomato pomace and Farmyard manure (Tp and FYM), and Tomato pomace and Compost (Tp and CM). Physical soil properties such as soil porosity and penetration resistance were improved by the application of organic blends. Additionally, soil nitrogen content ranged from 0.10% (control and NPK) to 0.13% (Tp and FYM). A significant increase of yield was noticed under organic fertilization where the highest yield of 8.00 tn ha−1 was recorded in Tp and BHS (2018). Lycopene content was significantly affected by fertilization and its highest values were 87.25 (Tp and BHS; 2018), and 88.82 mg kg−1 fresh (Tp and FYM; 2019). Regarding fruit firmness, the three organic blends did not have statistically significant difference. In addition, the Total Soluble Solids (TSS) was significantly affected by the fertilization and the maximum value was 4.80 ◦Brix (Tp and CM; 2018). In brief, tomato pomace blended with organic fertilizers was yielded considerable since it improved soil quality and increased yield.
