Winter onion variety Radar (Radar), also known as Raider, is one of the best options for winter cultivation due to its high winter hardiness and resistance to bolting. This variety is capable of withstanding temperatures down to -13 to -16 degrees Celsius without snow and down to -25 degrees Celsius with snow cover. Onions are planted 3-4 weeks before soil freezes, allowing for market-ready produce by May. Radar is valued for its high yield and disease resistance, including viral infections and powdery mildew. The bulbs of the Radar variety have round or flat-round shape with golden scales and medium-length necks. The weight of one bulb ranges from 120-150 g to 300 g. Inner scales are thick, juicy, crisp, and have a pleasant balanced semi-sharp flavor. The variety is characterized by high dry matter content, which ensures excellent taste qualities and makes it popular on the market. Onion is suitable for fresh consumption, culinary use, processing, and preservation. Radar is a versatile variety that suits both farmers and gardeners equally well. It delivers maximum yield with uniformly sized bulbs, is not prone to bolting, and maintains market appearance during long-term storage. Due to these qualities, Radar onion is widely used in commercial cultivation and sales, and is appreciated for its stability and reliability under various climatic conditions.
