OTRADA MID-RIPENING CULTIVAR OF SPRING OAT

Abstract

There are presented biological, agronomic and technological parameters and morphological traits of a new cultivar of spring oat, Otrada, for feed purposes. The cultivar was developed at the Research Institute of Agriculture for Northern Trans-Ural Region and put into the State Register of Breeding Achievements to be cultivated for feed purposes in the 9th and 10th Regions of the Russian Federation since 2013. The Otrada cultivar is mid-ripening of 69-74 days from coming-up to wax ripeness, mid-tall, with the height of plants of 77.4-112.5 cm, resistant to lodging. The average grain yield for the years of studying (2005-2013) made up 4.57 tons per ha as compared with the standard Megion of 3.92 tons per ha. The maximum grain yield of 6.32 tons per ha was obtained in the competitive variety trial nursery in 2006. The cultivar has sufficiently high output of grain (Kkhoz = 33.7 percent). Technological properties of grain are on a level with the standard Megion. The cultivar is resistant to grain fall and average resistant to spring-summer droughts.
