Results and prospects of European radish breeding

Relevance Currently, the first place goes to the creation of new high-yielding varieties and hybrids F1 crops that meet the requirements of modern industrial technologies. Heterosis hybrids have high yield, marketability, equalization, friendly yield and resistance to disease. Methods When developing new varieties and hybrids of radish suitable for mechanized harvesting, attention should be paid to the strength of the attachment of the leaf outlet and its upright position, the uniformity of immersion in the soil and the easy pull-out of root crops. Studies were performed in a protected (heated film greenhouse) and open ground in All-Russian Scientific Research Institute of Vegetable Growing – Branch of the FSBSI Federal Scientific Vegetable Center. Results The results of breeding work with European radish are presented. According to the results of expert evaluation, the state register of breeding achievements included two varieties of European summer radish – Bianca, Sirius and one hybrid of European winter radish – Tsyganskiy Baron F1. The new varieties are distinguished by uniformity in shape, length, diameter of the root crop, compact leaf rosette, form a root crop in a short and long daylight, recommended for cultivation under film shelters and in the open ground (early spring and summer sowing time). As a result of repeated inbreeding, inbred lines of European winter radish (brought to the seventh generation) were created, characterized by high equalization of the root crop, with strict self-compatibility. These lines were included in the process of creating heterosis hybrids. Evaluation of the obtained hybrids was carried out in the open ground. A hybrid of radish European winter Tsyganskiy Baron F1 – medium-ripe, flat-rounded root, black, weighing 220-260 g. Perspective hybrid in relation to the standard has a more aligned form of the root, with a rich black color and smooth surface. Tsyganskiy Baron F1 on the above indicators exceeds the standard night, resistant to stressful conditions.
