Assessment of economic and biological signs of Ribes aureum Pursh. forms in the conditions of the Orenburg region

Abstract

Over the past 20 years, research on the study and preservation of unique forms, varieties and genotypes of golden currant plants has been of particular relevance. The article presents the results of studying 10 forms of golden currant in terms of drought resistance, productivity and biochemical parameters. The research was carried out in 2018-2021 on the basis of the Orenburg branch of the Federal State Budgetary Research Center of Horticulture. The forms of golden currant 2009 planting were used as objects of research: 1-1, 1-2, 1-3, 1-4, 1-5, 1-6, 2-1, 2-2, 2-3, 2-6. Planting scheme is 3.0 ? 2.0 m. The purpose of the research was to study the gene pool of golden currant and identify promising forms with a complex of economically valuable traits. It was found that forms 1-1 (6.7 kg/bush), 1-2 (7.1 kg/bush), 1-3 (7.9 kg/bush), 2-2 (6,3-5,9 kg/bush), 2-6 (6,4-6,0 kg/bush) are characterized by high productivity. The highest average berry weight was observed in forms 1-1 (2.22 - 1.92 g) and 2-6 (2.46 - 2.33 g). Taking into account the complex of indicators (drought resistance, the number of berries in the brush, the average weight of berries, productivity, ascorbic acid, sugar), the most promising forms of golden currant 1-1, 1-3, 2-6 were identified. They can be recommended for the conditions of the Orenburg region.
