Revolutionizing Narrow-Scope Potato Breeding: Using Dry Matter and PVY as Selection Criteria for High Quality Cultivars

Potato is one of the most important plants in terms of yield potential, adaptability and nutritional content. Although potato breeding programs are integrated with many new technologies, they are intensively carried out by phenotypic observation and selection in field conditions. In the research, high dry matter content and PVY resistance were determined as the basic selection criteria in the development of new cultivars. The research was carried out between 2017-2022 using 30.000 F1 potato seeds as genetic material and by establishing comparative trials in different locations with commercial control cultivars. Selection and breeding studies were carried out considering PVY resistance according to the molecular marker test. As a result of the research, commercial candidate advanced lines suitable for PVY resistance, table, chip and French fry potato industries were developed by conducting phenotypic and genotypic selection and selection studies according to high dry matter content. Based on the findings of the present study, the lines 82-88-04, 82-45-24, 82-105-50, 82-78-16, 82-56-01, and 82-93-03, distinguished by their high yield potential and resistance to Potato virus Y (PVY), were identified as possessing significant potential for official registration and subsequent commercialization as candidate cultivars.
