A new variety of Chinese radish (loba) Serdtse Podmoskovya for the Central region of Russia

Abstract

The article presents the results of the selection work of the laboratory of breeding and seed production of table root crops of the Federal Scientific Vegetable Center for the culture of Chinese radish (loba). From the collection material (a total of 23 samples were studied), a promising material was selected under the number No. 600 for a complex of economically valuable features. The purpose of the research is to create a variety of Chinese radish – loba for open and protected ground. Based on this goal, the objectives of the research included: to evaluate a promising variety of loba in a nursery of competitive variety testing in open and protected ground conditions, to assess alignment according to the main morphobiological parameters, as well as to assess the safety and resistance to diseases during storage.Results. As a result of repeated individual and family selection in the direction of productivity, resistance to premature stem formation and diseases of vegetation and storage, as well as improvement of taste qualities, a new variety of Chinese radish Serdtse Podmoskovya was bred. The new variety belongs to the pink-red rounded varietal type. The root crop is flat-rounded, large in size. The flesh is white, juicy, with a slightly spicy taste. The variety is medium-ripened, the growing season is 65-75 days, suitable for use in early summer, autumn and winter, resistant to longterm storage (95-96% preservation) and low light. The yield of the variety in protected ground is 2.7 kg/m2, marketability – 88.7%, root crop weight – 533 g; dry matter content – 6.26%, sugars – 2.56%, ascorbic acid – 19.36 mg%. The variety on this background was distinguished by the absence of flowering and diseased plants. The yield in the open ground was 31.2 t/ha (3.12 kg/m2), marketability – 81.2%, root crop weight – 281 g. The variety under these conditions was characterized by a higher content of dry matter –11.0%, sugars – 3.2% and ascorbic acid – 20.13 mg%; a small percentage of flowering (9.4%) and affected plants (6.3%) was noted. For this variety, a technology has been developed for obtaining original and elite seeds according to a one-year development cycle in the conditions of the Central region ща Russia.
