Productivity and economic and biological features of the oat variety Groom

The article presents morphological, biological and economic indicators of a new promising variety of spring oats Grum. The results of competitive variety testing in the Ulyanovsk region and State variety testing in the regions of the Russian Federation are presented. The variety was created in the Ulyanovsk research Institute of agriculture, together with FITZ «Nemchinovka». The Grum is referred to the middle-ripening group of varieties, matures 2-3 days later than the standard variety of Konkur. Regardless of the growing conditions Grum forms high grain nature (512-565 g/l), with the mass of 1000 grains from 31.5 to 38.5 g. The grain yield of varieties Grum in the years KSI ranged from 4.41 to 4.85 t/ha. The excess over the standard grade Showjumping over the test period averaged 0.28 t/ha. the average yield of grain stations over the years, the SVT was 3.75 t/ha. Maximum grain yield equal to 11.00 t/ha was obtained in 2017 at GSU Schigrovskogo Kursk region. This result indicates a high genetic potential of productivity of this variety of oats. The plants of the new variety are characterized by a thick strong stem and good leafiness, which allows us to recommend the variety for use as a component for sowing in a mixture with annual legumes for hay, as well as silage and green fodder. The results of the SVT on the study of feed productivity prove the ability of the Grum variety to form a high yield of dry matter up to 12.40 t / ha. Since 2019, a new variety of spring oats Grum is included in the State register of breeding achievements approved for use in the Central, Volga-Vyatka, Middle Volga and Ural regions. It is recommended for cultivation in Ryazan, Tula regions, the Republic of Mari El, Nizhny Novgorod region, the Republic of Mordovia, Penza, Ulyanovsk and Orenburg regions for grain fodder and green mass.
