Assessment of breeding material european small radish for salad lines

Abstract

Relevance. In connection with the development of industrial hydroponics in the country, the need arose to create targeted varieties and hybrids of F1 small radish for salad lines, which have special requirements. They should be productive, early ripening and shade-tolerant, with a rounded root shape and a small compact rosette of leaves, resistant to premature stem formation (stem formation). Root vegetables should be juicy, dense, without voids and bitterness, as well as with a high content of ascorbic acid and other biologically active substances and low accumulation of pollutants.Methodology. The material for the study was selection samples of small radishes created in the laboratory of selection and seed production of table root crops of the Federal State Budgetary Institution " Federal Scientific Vegetable Center". The assessment of promising breeding material was carried out in the seedling department of the Richel greenhouse and in the production conditions of Moskovsky LLC according to the methods adopted by the Federal Scientific Center.Results. Based on the assessment results, promising leveled material was identified, adapted to the conditions of salad lines, both in terms of a set of characteristics and in individual areas of selection: No. 81 with high yield and marketability, having large red root crops of a round-oval shape and a small leaf rosette, No. 83 – with large roots, small leaf rosette and resistance to flowering, No. 80 is a genetic source of high resistance to flowering (3.6%) combined with marketability and a small leaf rosette. Genetic sources of high dry matter content were identified – the Dutch hybrid F1 Gloritet, monosaccharides – sample No. 83, ascorbic acid – No. 76, 81, 82, 84, high content of vitamin "C" and monosaccharides in root vegetables – No. 76. In the production conditions of Moskovsky LLC, three promising samples small radishes stood out with a yield of more than 2200 g per 1 m2 and a marketability of 93.9-96.8%, distinguished by large rounded red root crops, a small rosette of leaves and a thin axial root.
