Within the researches and works during in the previous years in the Republic of Moldova were obtained a number of grapevine varieties, resistant to the adverse winter conditions, characteristic for this region, located on the northern limit of industrial viticulture, which allowed the considerable reduction of losses of resources and investments in the process of production of grapes and increased the money income and efficiency of the local producers. At the same time, it is strictly necessary during the nearest time to obtain new varieties with multiple resistance to pests and diseases in conditions of high heat and humidity, that will also keep already the obtained properties of the high quality of production and resistance to adverse winter conditions. At the same time, under the current and future climate and socio-economic challenges with their multiple and unpredictable effects on the viticulture, the spectrum of necessary features required by the producers become more wide, as well as the limits of the expression of these features.
The genetic traits highlighted and confirmed in the ampelographic collections can be used as criteria in evaluating, selecting and introducing the necessary genetic resources as sources of useful characters. This process involves searching, associating of the necessary ones, first of all, in the frame a very wide and diverse informative material, that becomes at the same time more and more voluminous. Rapid and efficient evaluation can significantly accelerate their mobilization and use in the process of improving of the assortment.
The accumulation of a large volume of information in international Data Bases, including free access, offers new opportunities in the evaluation of the existing grapevine genetic resources, therefore, the faster identification of the useful characters for the breeding process, the eventually geographical location of the sources of biological material for introduction.
For the purpose of the initial processing, under various aspects, of the available genetic-molecular information, the functionality of the Information System for the management of genetic resources from the Institute’s Genofond was extended. The ampelographic description was completed, according to the OIV Descriptor, with the descriptors OIV 801 - OIV 806 (SSR-markers), and the information carried out in the previous projects (INTAS, SeedNet , COST FA1003 et al.), concerning some autochthonous genotypes, were introduced in database. The modules of Information System, which allow reading, storing, fragmenting or aggregating information, according to the formulated criteria have been developed.
An attempt was made to test the hypothesis of subtraction of genetic information, which would possibly show the difference in resistance to pathogens between V. rotundifolia Michx. and V. Vinifera L., based on the V. rotundifolia Michx. limited DNA sequences available in the NCBI database.
The presence in the same Informational System of the heterogeneous data (phenological, phenotypic, ampelographic, agrobiological, genetic-molecular), which include a broad spectrum of genotypes, will ensure easier association of traits useful for the genetic improvement process. The development of the functionalities is envisaged in the direction of completing, ensuring the junction with the bioinformatic methods.
