Abstract:

Infections with potato virus Y could reduce yield with 50-90%. An imposed priority is to identify healthy initial material and to use resistant varieties against this virus attack. On last three decades new aggressive viral strains (necrotic strains) appeared. These strains broke some varieties resistance, some of them causes tubers symptoms. Damages are quantitative (yield decreasing), qualitative (tubers marketable depreciation), financials (ware potato is un-saleable, seed potato is rejected from certification). The researches of this project will contribute to find solutions, new methodological concepts to reduce these damages through identification and implementation of new methodological solutions. The main project objectives are: elaboration of an innovative solutions to improve control system efficiency of necrotic, emergent strains of potato virus Y, pathogen with high spatial incidence, elaboration of a study regarding evolution of Y virus strains spectrum in Romania, correlated with imports level and climatic conditions from the last 20 years, identification of native and foreign varieties, resistant breeding lines to PVY necrotic strains.

To achieve the proposed objectives, the main activities of the project are oriented in three directions, pursuing assessment of the following aspects: 1) the pathogen biology (PVY viral strains identification- establishment of spatial spread of PVY strains at different genotypes collected from 4 geographical areas of potato: Brasov, Cluj, Harghita, Covasna ); 2) the host biology (identification of some potato genotypes with high resistance/tolerance to necrotic strains); 3) environmental aspects (climate, edaphic data collecting; correlations between the frequency of necrotic PVY strains viral infections and climatic conditions from areas where potato tested material was cultivated; identifying areas with high frequency of PVY necrotic strains infection to achieve the risk maps).

The results of the researches will be used for:

- elaboration an innovative technologies for improving the control system efficiency over the new PVY necrotic strains, especially those that produce necrotic staining ring on tubers (use of recommended varieties, strict control of these viral strains on potato certification, using of PCR technique for samples indexing, avoiding areas with epidemiological risk, new techniques of identifying-spectral analysis, precision agriculture-of pathogens and rapid information transmission to all actors on potato pathway, thereby avoiding the virus expansion).

- formulation virtual models regarding potato future situation in our country, if necessary measures will not be taken in order to stop viral diseases caused by these pathogens, measures that are specified in the innovative technology.

The project promotes original researches, development of knowledge on domain (new viral strains affects world potato crops).

Gaining new information upon evolution of the new viral strains in our country, establishing correlations with different factors, original concepts will be formulated (these will contribute to increasing visibility of Romanian researches). The project will elaborate a new strategy for potato crop protection against PVY new necrotic strains to get health, clean seed material. From these results will benefits potato producers, decisional organisms of Ministry of Agriculture and Rural Development, National Federation of Potato from Romania, which will establish adequate policy for potato producing, varieties structure, orientation of potato production in our country.
