Abstract

The article presents the results of a study carried out by the Breeding and Seed Production Center Agrostar LLC, Russia. The results were obtained for the conditions of the Middle Volga region based on the assessment of the yield of seed potato seedlings. The source material for the research was obtained from the Lorch Potato Research Institute, under a joint breeding agreement. As a standard, the regional variety Rosara was used as an early high-yielding potato with excellent taste and resistant to disease. In the test field nursery in 2019, 34 hybrid populations of 40-60 pieces were planted. Promising bushes were selected out of these pieces for further selection and for the creation of potato varieties suitable for cultivation in the soil and climatic conditions of the Middle Volga region. These selected promising strains have high productivity ( > 35.0 t/ha), dry matter mass content (up to 23.0%) and starch mass (up to 17.0%) exceeded the variety Rosara standard in these indicators. The selected strains showed resistance to alternariosis, scab.
