Evaluation of potato varieties as a source material for selection

Abstract

The article presents the results of research on creating a source material for breeding new high-yielding potato varieties adapted to the conditions of the southern part of the Volga-Vyatka region. The research was carried out in the Department of selection and seed production of the Chuvash research Institute. The soil of the experimental site is gray forest, heavy loam, of medium fertility. Field and laboratory studies were conducted using generally accepted methods. More than 150 varieties have been studied in the collection nursery. The selected samples are valuable material for further selection and are identified on the basis of productivity. As a result of studying potato varieties of different groups of ripeness, highly productive varieties were selected for using the source material: 3 varieties were selected for each group of ripeness after the yield of marketable potatoes; 4 varieties with an increased number of tubers were selected.
