Development of a decision-making algorithm for the selection of varieties for specific edaphoclimatic conditions
The article presents the results of research aimed at creating competitive, highly productive vineyards with stable fruiting and high quality grape-wine products. An approach based on the creation of software based on established relationships and interdependencies in the "soil-plant-climate" system is proposed. The purpose of the research was to develop a decision-making algorithm for the selection of optimal grape varieties for specific edaphoclimatic conditions and a PC for its implementation. The objects of research are grape varieties of various ecological and geographical origin. The source of information about grape varieties was: the All-Russian ampelographic collection (city of Anapa), the collection of ARNRIV&W «Magarach» (Republic of Crimea), the collection of ARRIV&W named after Ya.I. Potapenko (Rostov region), Dagestan collection (city of Derbent). Modern methods of modeling and information technology were used as a methodological basis for research. Competent selection of variety when laying a vineyard is one of the main factors in the formation of competitive plantations. It is necessary to take into account requirements of variety for the temperature regime of the cultivation zone (the sum of active temperatures, minimum temperatures and the frequency of their repetition) when selecting a variety, in the case of grafted planting material, the affinity of the graft-rootstock combination and the characteristics of the rootstock. On the basis of the conducted research, an algorithm for selecting varieties and rootstocks for specific edaphoclimatic characteristics of the area of cultivation of grape plantations has been developed, which will ensure the highly efficient use of the genetic properties of varieties and the edaphoclimatic potential of the cultivation zone. The next stage of research was the direct programming of modules for calculating the selection of varieties according to specified criteria, which will allow creating software (PC) for the decision-making process for choosing the optimal grape varieties for specific edaphoclimatic conditions.
