The development of new varieties spring barley for use for feeding purposes

The aim of the study was to create barley breeding material for feeding purposes. The work was performed under conditions of the Krasnoyarsk forest zone. The best varieties were tested on the experimental fields of Krasnoyarsk region and Tyumen region. The Acha variety was the standard of corn yield, Sobolyok was for the green mass yield. The initial stock in the hybridization breeding was presented by varieties Krasnoyarsky 80, Kedr, Sobolyok selected by Krasnoyarsk research institute of Agriculture and multiserial sources of resistance against loose smut, they were Conquest, Bonanza, Paragon, Heartland №1 (Canada), Woodvale, Luther (USA). New varieties were crossed with each other and with new, more productive varieties of barley. The strict selection for productivity, resistance against loose smut and the green mass yield was conducted during the breeding work. The variety Krasnoyarsky 91 stood out under conditions of Krasnoyarsk region. It is a pallidum variety. This is a middle-late variety with the vegetation period of 75-85 days. During 2012-2015 average productivity of grade was 30.4 centner/hectare from 25.4 to 40.5 centner/hectare), it was 4.4 centner per hectare higher than the standard Acha and 5.6 centner per hectare than variety Sobolyok. Krasnoyarsky 91 exceeded Sobolyok by green mass yield by 54 centner/ hectare. The variety Uvatsky was the best in corn yield under conditions of the Tyumen region. It was a pallidum variety. This is a middle-late variety. During 2013-2015 average productivity of grade was 69.1 centner/ hectare (from 59.4 to 83.7 centner/hectare) it was 14.4 centner per hectare higher than the standard Acha. In a green mass yield Uvatsky exceeded Sobolyok and had one slightly less than Krasnoyarsky 91. The superiority of multi-row varieties by a green mass yield was revealed. New varieties of barley exceeded in grain productivity the variety of grain direction Acha and in the green mass yield they exceeded Sobolyok.
