Resistance To Diseases

In the CREA-Viticoltura ed Enologia, Lab of Turi, during the last ten years, we started a breeding program for table grapes to obtain new seedless varieties, by using conventional breeding by crossings, and embryo rescue techniques. Other than seedlessness, additional targets for this breeding program are: the possibility of extending the harvesting period, the attitude to cold storage, transport and shelf-life, resistance to diseases both on the plant and in post-harvest conditions, the good productivity, the quality of the grapes, the easy cultivation management of the vineyard (reduced water, nutritional requirements, etc ...). More than 10.000 new genotypes have been obtained through the use of over 20 table grape varieties and more than 18 different crossing combinations. The following characteristics have been observed on these individuals for more than three years: berry color, length and weight cluster, average berry weight, sugars, pH, acidity, class of seedlessness, floral morphology, resistance to diseases. The results of these activities revealed that some combinations have better performance among all. In the near future, this activity will allow to focus on parental genotypes able to provide individuals with the best desired traits.

A field trial was established in the Mildura district, to compare the effects of trellis type (single T, double T, Y and sloping T) on the yield and fruit quality of 5 table grape varieties (Cardinal, Waltham Cross, Italia, Ruby Seedless and Emperor). Over a 3-year period (1978-80), berry yield proved insensitive to trellis type for most varieties and also as the mean of all varieties in 2 years out of 3; however, the 3 larger trellises led to significantly (P<0.05) increased berry Brix levels, improved red colour levels on Cardinal, Ruby Seedless and Emperor grapes, and higher mean berry weights for Cardinal, Waltham Cross and Italia varieties, compared with grapes grown on the single T trellis. Since differences in Brix, red colour levels and berry size were, generally, not significantly different between the 3 large trellises tested, and the sloping T trellis is simpler and easier to erect, it is concluded that the sloping T trellis is a suitable, cost-effective trellis to use for the production of table grapes in the Murray Valley.

The main problems of grape storage are berry dehydration and rot. One of the solutions to reduce rot and preserve the quality of grapes during storage is the use of aerosol treatment with calcium content before storing. The aim of the study was to evaluate the effect of physiologically active substances based on calcium in various concentrations on the quality and organoleptic characteristics of table grape cvs. ‘Italia’ during long-term storage. The effectiveness of the studied systems of treatment was evaluated according to the content of sugars and titratable acids, the activity of the redox enzymes of polyphenol oxidase and peroxidase, weight loss of bunch and organoleptic properties. The greatest effectiveness established by using preparation of Master Green Ca, Brentax KCa, and Brentax Ca (in concentration 150g / 20l). Experimental treatments significantly decreased the weight loss of bunch (less than 4%), and preserved organoleptic properties of berry at a high level (8.2-8.9 points). Decrease in the activity of oxidative enzymes had a positive effect on the quality of table grapes and contributed to its better preservation. The data obtained make it possible to rationalize the system of long-term storage of grapes by using of aerosol treatment with calcium-based preparation.

The aim of this study was to determine the volatile profiles of new seedless table grape cultivars Timco™, Magenta™, Krissy™ and Arra15™ and compare them with the traditional table grape variety Crimson seedless. The volatile profiles were extracted employing solid-phase microextraction and analyzed with gas chromatography coupled with mass spectrometry. Terpenes were present in very different proportions, with the Magenta, Krissy, and Arra15 varieties showing much higher quantities than Crimson and Timco. β-Ionone and octanal, important indicators in the aromatic flavor quality of table grapes, were present in higher levels in Crimson and Arra15, and this might be responsible for driving consumer preference. These compounds significantly increased during ripening, except in Crimson, and gradually decreased from harvest to the end of the storage in all the cultivars. Evolution during ripening was different depending on the variety but the general tendency terpenes was to increase from veraison to harvest. A postharvest study revealed that Crimson could have a better conservation of the volatile components during postharvest storage compared with Timco and Krissy. These results could help in plant breeding programs and to make decisions for new planting according to needs for storing fresh table grapes given distances to consumer markets.

Grapes are rich in easily digestible carbohydrates, mineral compounds, vitamins, phenolic compounds. and other vital components. It is known that fresh grapes can be used from September to December. To prolong the terms of consumption of this valuable raw material, the most appropriate varieties and conditions for storing grapes have been determined. White, pink, and red grape varieties were taken as the object of research. The changes in the activity of the pectinesterase enzyme were determined depending on the degree of ripening of table grape varieties, the change in the pectinesterase enzyme during storage of table grape varieties in various variants was investigated. Statistical processing and calculation of variations in the indicators of changes in the activity of the enzyme pectinesterase were performed, depending on the degree of ripening of grapes of the Shamakhi Marandi variety. During the study, the pectinesterase enzyme remained more stable in mature varieties. This means that in ripe table grape varieties, the absorption of nutrients in the respiratory process is significantly slowed down. However, as they mature, the activity of the pectinesterase enzyme gradually increases. Therefore, for long-term storage in refrigerated chambers, fully ripe varieties of table grapes were used; to this end, grapes of the white Ganja table variety, the pink Shamakhi Marandi variety, and the red Black Asma variety are more suitable. The comparison of the investigated variants showed that table grape varieties, when stored in a refrigerated chamber in a controlled atmosphere, at 3–4 % CO2 and 2–3 % O2, retain better quality than other variants. When storing table grape varieties of various variants in the refrigerator, the enzyme activity decreases but is not completely suppressed.

The paper presents the results of a study on the content of free amino acids, including essential ones, vitamins C and P, biologically important macro- and microelements in table grapes of the middle ripening varieties Ag raisins, Vezne, Galan, Hamburg Muscat and Samur, cultivated on the plain in Southern Dagestan Region. The qualitative composition and quantitative content of free amino acids were determined by HPLC on an AAA-881 analyzer. Amino acids tryptophan, cystine and methionine were identified by paper chromatography due to the fact that they decompose when exposed to a temperature of 102 ° C in the amino analyzer reactor. The mass concentration of vitamin C was identified titrimetrically, vitamin P was identified colorimetrically (FEK-56M, Russia), the mineral composition of grapes was identified by flame and atomic absorption photometry using Flapho-4 (Germany) and Hitachi-208 (Japan) devices. Each of the varieties had 18 amino acids, including a full set of essential ones. The total number of detected amino acids was 368.5 (Ag raisins) - 279.9 mg / dm3 (Vezne), and irreplaceable ones - from 103.8 (Hamburg muscat) to 132.4 mg / dm3 (Ag raisins). All experimental grape samples contained vitamins C, from 2.6 (Galan) to 3.7 mg / dm3 (Ag raisins) and P - from 78.0 (Samur) to 131.3 mg / dm3 (Galan), as well as physiologically important minerals. Studies have shown that in terms of the amount of free amino acids, including essential vitamins C and P, healthy minerals, such grapes as Ag raisins, Vezne, Galan, Hamburg and Samur Muscat, grown in the south of Dagestan are natural products with functional properties. Eating it fresh contributes to the normalization of metabolic processes in the human body. Additionally, these grapes can be successfully used as a raw material for the production of multicomponent functional food.

Medical benefits derived from grape extracts and red wine have been recently documented. In these regards, fresh grapes were collected from six Italian table grape varieties grown at the Rutgers Fruit Research and Extension Center in Cream Ridge, N.J. These samples were analyzed for proanthocynidins (PACs) which are the nutraceutical compounds considered to be bioactive in grapes. Seeded red grapes, seedless red grapes, seeded purple grapes and seedless green table grapes were also purchased from a New Jersey supermarket and analyzed for PACs. An LC/ESI-MS analytical method under low CID level of 20% was used to quantitate the PACs. Separated proanthocynidins (PACs) were individually analyzed and determined by their molecular ion peaks under positive ion mode, and led to the identification of dozens of proanthocynidins (PAC). Using HPLC/ESI-MSD, the proanthocyanidin monomers, (+)-catechin (C), (-)-epicatechin (EC), (-)-catechin gallate (CG), and (-)-epicatechin gallate (ECG) in these fresh grape samples were quantified under MRM mode. These identified catechins are the same phytochemicals that exist in green tea which is renowned for these same healthful components. This research revealed that the total concentration of PAC monomers in the six fresh table grape samples from New Jersey grown grapes ranged from 0.009% to 0.04%, which is much higher than that found in the four fresh table grape samples purchased from supermarket that contained concentrations from trace level to 0.005%. While the New Jersey grown grapes could not be directly compared to the supermarket grapes, this study provides a base-line data of expected PAC levels from standard supermarket grapes, and shows that these Italian grape varieties grown in New Jersey were rich in PACs.
