Использование сортовых ресурсов озимой пшеницы в Ростовской области
Abstract
The use of the varietal resources of winter wheat in the Rostov region The Rostov region is one of the principle regional producers of winter wheat. Russia possesses vast varietal resources for all regions of the country, so there is an increase of winter wheat varieties, used in the agriculture. In 2016 in the Rostov region there were 127 winter wheat varieties that on 17 pieces more than in 2015. In 2016 the varieties being in the production for 6-10 years (42.9%) became widely spread. It testifies that the varieties become widely spread only after six years of zonation and that fact has a negative effect on productivity. The areas sown by new varieties reduced with the share of 11.6%, so the present resource-varietal potential is used inefficiently. To realize the advantages of the new variety, the crop rotation should be made according to the plan. The organization, technology and methods of seed production are of great importance for variety renovation and change. Stable grain production in any country is based on the ability to use the latest breeding achievements.
