Source material for potato breeding for productivity in the forest-steppe conditions of Novosibirsk Priobye

Abstract

. The authors studied the potato collection in 2019-2021 as part of a comprehensive research plan for the implementation of the subprogram “Development of potato breeding and seed production” based on SibNIIRS - a branch of the ICG SB RAS (Siberian Research Institute of Plant Growing and Breeding - a component of the Federal Research Center of the Institute of Cytology and genetics of the Siberian Branch of the Russian Academy of Sciences). The study aims to determine adaptive and high-yield potato varieties and their suitability for breeding. The authors presented the results of a survey of 13 potato varieties distinguished by productivity. The foreign variety Gala was taken as a standard since it is in the top ten cultivated areas in the Russian Federation.In 2019, the standard variety Gala had the highest yield among the tested varieties - 1653 g/bed. In 2020, all the studied varieties exceeded the standard; the authors note the maximum productivity in the following types: Terra (1067 g/bush), Kumach (1076 g/bush), and Prizer (1081 g/bush). In the last year of the study, two varieties significantly exceeded the standard variety: Terra (1280 g/bushel) and Sadon (1377 g/bushel). On average, over three years, the highest productivity was noted in the variety Alaska (1229 g / bush). Over the years of the study, 46% of the studied types distinguished themselves by their high productive ability and had an adaptability coefficient of more than 1. The authors note the highest value of the adaptability index in the variety Alaska (1.07). High marketability of tubers (over 97%) was observed in 11 out of 13 tested types. Low fertility and lack of natural berry formation in widely productive potato varieties make it difficult to use them in breeding for high productivity. In the foreststeppe conditions of the Novosibirsk Priob’ye region, the following types are suitable for breeding for increased productivity as pollinators: Salsa, Signal, and Gala having fertility from 50 to 90%. The authors also noted high natural berry production (7–9 points) in four varieties: Sadon, Prizer, Signal, and Gala. These varieties are recommended for the breeding process as mother plants.
