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.

Highlights

Maintaining the conditions necessary to keep modern potato varieties in the optimum selling condition during long periods of storage is expensive
As a result of this, several tasks to be performed prior to the selection process have been identified, which can split into 3 parts namely: general, zonal and special
In future years, when selecting the achieved generations with the participation of the parental form (Innovator, Velox), it is planned to conduct a study on the suitability for processing into french fries

Summary

Introduction

Maintaining the conditions necessary to keep modern potato varieties in the optimum selling condition during long periods of storage is expensive. This expense significantly increases the overall cost of the product. For this reason, potato farmers in central Russia are in extreme need of potato varieties with new advantageous characteristics and a faster ripening period. Since the inheritance of beneficial characteristics of potatoes is due to aspects of gene interaction, the analysis and selection of parental forms allows one to achieve certain indicators in the process of breeding [1]
