Analysis and selection of parental forms for crossbreeding of early potatoes for the arid conditions of the Middle Volga region

Abstract

In the modern changing climate, selective breeding has been essential for increasing production and ensuring stable yields. Potato varieties with different ripening periods are suitable for the conditions of the Middle Volga region. High-yielding varieties resistant to mechanical damage and diseases, varieties with increased heat resistance and a complex of other important features are being created. The emergence of new directions has complicated the solution of breeding programs and required the orgaization of an intermediate stage in this work: the identification and use of special parent forms - carriers of useful qualities. This is a basic, but necessary task when involving a variety of genetic material in the selection process. Research on the topic was carried out in 2017–2019 in the Samara region (RF) in a special shielded area of AGROSTAR LLC in cooperation with experts of the potato farm of VNIIKH FGBNU, MAG LLC (Kinel), Agrocenter Korenevo LLC, and with the participation of experts of Bavaria-Saat GmbH, Germany.
