Abstract

The need to create a multifunctional electronic system for documentation of the grape gene pool, focused on the characteristics of its ecological potential, has been updated. The step-by-step development of the system architecture of the grape gene pool documentation program, including the program interface, is presented. As the characteristics that most fully describe the economically valuable characteristics of grape varieties, 85 indicators were selected, and they were grouped according to functional characteristics into 9 groups. The logical structure was created and the physical design of the database was carried out. An electronic information Database has been formed, the development of which is focused on the characteristics of the obtained potential of genotypes carrying breeding significant traits, their classification, certification and areas of use. In the process of research, the screening of the grape gene pool by environmental parameters was carried out, which are based on analytical methods grouped that make it possible to obtain a complex of physiological and biochemical indicators characterizing the resistance of plants to extreme stress factors of the environment. To implement the task of varieties selection according to specified criterions, three algorithms are implemented depending on the type and user requirements for the selected varieties. In view of the environment stress full increasing and the need to focus on the ecological characteristics of varieties, the algorithms for their assessment have been developed with a focus on weather and climatic peculiarity. In order to rank variety forms according to the degree of resistance to dehydration and extreme low and high temperatures, a scale of tester varieties (standards) from low to highly resistant has been developed. The original own scale is proposed to assess every type of resistance.

Highlights

Many countries of the world are implementing the national programs for the preservation and use of plant genetic resources (France, USA, India, Italy, Spain, Portugal, Germany, etc.), in which the most important direction is given to the identification and breeding use of donors of the most important grape breeding traits [8, 9]
