The productivity and quality of seeds of wheat varieties Tyumenskaya Yubileynaya and Tyumenochka depending on the terms of sowing and norms of seeding in the northern forest-steppe of Tyumen region

The purpose of the researches was to study the productivity and quality of seeds of varieties of wheat depending on the terms of sowing and norms of seeding in the northern forest-steppe of Tyumen Region. In the last decade the scientists ofNorthern Trans-Urals SAU created two middle early varieties of spring-wheat Tyumenskaya Yubileynaya and Tyumenochka. The first of them is semiintensive type, it has passed the state variety testing and is included in the register of selection achievements across West Siberian Region, the second is intensive type and is in a variety testing. On experimental field of Northern Trans-Urals SAU on new varieties of wheat of high-quality technology of cultivation on seed and food purposes has been developed. It was established that productivity of seeds at the first term of sowing (on May, 5-10) in the variety Tyumenskaya Yubileynaya changed from 2.52 to 2.69 t/hectare, in Tyumenochka - from2.46 to 2.68 t/hectare. On productivity of seeds between options both varieties had the difference within an experience error...
