“…This indicated that these genetic parameters are unstable with different environmental conditions. Similar results were obtained by Garg et al, (2008), Adalid et al, (2012 and El-Nagashy (2012). CONCLUSION In conclusion, due to the pervious results, which confirmed the role of both additive and non-additive genetic variances in the inheritance of studied traits with different levels, the suggested suitable breeding program for improving these traits is recurrent selection program for vegetative traits and production of hybrids for fruit characters and chemical traits.…”

Knowledge about the mode of gene action of economical traits (which directly contribute towards yield and fruit quality) in any crop like tomato (lycopersicon esculentum L.) helps to formulate the genetic basis for breeding. Thus, the aim of the present study was to estimate different types of gene action affecting some characteristics of tomato. For this purpose, five tomato varieties were used. These varieties were: Advantage 2 (P 1 ), Cherry (P 2 ), Fatma (P 3 ), Edkaway (P 4 ) and Castle Rock (P 5 ). The varieties were crossed by using complete diallel crosses mating design, in order to produce 20 hybrids. All genotypes were evaluated during two seasons for some vegetative traits, fruit characteristics and physiological traits. The data were subjected to biometrical analysis and the obtained results revealed that the mean squares of entries were highly significant for the studied traits, leading to the further partitioning of genetic variance into its components. The combined data over the two seasons showed that additive genetic variances were higher than their corresponding values of dominance genetic variances for plant height and number of primary branches per plant. On the other hand, values of dominance genetic variances were higher than their corresponding values of additive genetic variances for leaf area, fruit characters and chemical traits. Furthermore, heritability in broad sense (h 2 b%) was 93.15% for plant height, 85.32% for number of primary branches per plant, 78.68% for leaf area, -92.38% for locules number per fruit, 97.02% for firmness fruit, 68.78% for Pericarp thickness, 71.62% for total soluble solids, 81.58% for ascorbic acid content and 87.13% for lycopene content. However, heritability estimates in narrow sense (h 2 n%) were more less than the corresponding values in all studied traits, indicating that the role of non-additive genetic variance in the genetic expression of these traits are non-negligible. These genetic parameters could be used in carrying out breeding programs suitable for Tomato.

“…This phenotype would indi-cate an effect similar to the Beta mutant, which entails a mutation in the promoter of the CYC-B β-cyclase, increasing the level of transcription and resulting in increased levels of β-carotene at the expense of lycopene (reviewed by Cebolla-Cornejo et al, 2013). CATIE14812 also reached a β-carotene content higher than CDP4777 which was previously described as a good material for the improvement of this carotenoid in tomato (Adalid et al, 2012).…”

“…Two breeding lines FORTUNA-C and CDP8779 (alias NE-1) were also provided by COMAV (Spain), and were included as a reference of standard to low carotenoid content considering results of previous studies. As references for high carotenoid content accession LA-3538, which carries the high pigment 1, hp-1, gene (Jarret et al, 1984), and accession CDP4777, with high β-carotene content (Roselló et al, 2011, Adalid et al, 2012, were included. Finally, accession BGV5655 was also included as a traditional variety with intermediate lycopene content (Adalid et al, 2007).…”

The development of varieties with a high content of antioxidant compounds, such as carotenoids, has become a major focus in the marketing of tomato. Several mutants have been used in the development of high pigment varieties, but the significant influence of the environment on carotenoid content and the presence of negative side effects in vegetative growth and yield have limited the success of these variants. Consequently, the identification of alternative sources of variation in the quest for high carotenoid content is ongoing. In this study, 12 accessions of Solanum lycopersicum (including the former var cerasiforme) and S. pimpinelifolium

“…As an alternative, the development and use of genetically resistant cultivars represent satisfactory strategies from the social, economic, and environmental point of view for the control of late blight [4]. In this context, the transfer of resistance genes listed under tomato accesses in Gene Banks appears to be a suitable alternative, especially for the same species that are to be improved, since it facilitates crosses for gene transfer [5] and faster recovery of the desired agronomic characteristics [6].…”

Proteomics techniques were used to study the molecular mechanisms involved in the defense of tomato against late blight (Phytophthora infestans). Proteins were extracted from resistant access BGH-2127 and susceptible cultivar "Santa Clara". Leaves of the inoculated and non-inoculated (control) genotypes were collected at 0, 2, and 48 h after inoculation and analyzed by two-dimensional electrophoresis (2-DE), followed by identification with mass spectrometry (MALDI TOF-TOF). A total of 56 differentially abundant proteins were identified, of which 39 were resistant genotypes and 17 were susceptible. These proteins were categorized into functional groups of energy and metabolism, photosynthesis, stress and defense, transcription, other proteins, and as un-characterized ones. For access BGH-2127, oxidative stress proteins (2-cis peroxiedoxin BAS1 and 2-cis peroxiredoxin) and thaumatin-like protein showed increase in the relative abundance at 0 and 48 h of inoculation, respectively, and were therefore considered important for the defense mechanism of this genotype. The expression standards evaluated by real-time PCR differed from the results of the proteomic analysis. The protein-protein interaction networks provided important information on the cellular activities involved in the resistance of BGH-2127 late blight.
