The influence of small grain percentage on the formation of oat groats properties

The development of oat varieties for groats production is a topical issue, therefore the research goal was to study the influence of small grain percentage on groats yield and to evaluate the correlation relationship of this character with the quality indices. The research was carried out in the Grain Quality Laboratory of the Siberian Research Institute of Agri- culture from 2014 to 2016. The research objects were 20 oats accessions from Competitive Variety Trial Nursery of the Oats Selection Laboratory (Siberian Research Institute of Agricul- ture) including 14 filmy and 6 hulless oats accessions. The accessions were evaluated according to the methodology of the State Commission for Variety Testing. The study of dy- namic pattern of t ‘small grain percentage’ character in oats accessions showed that on 3-year average filmy accessions had low percentage of small grains (less than 5 %) - 0.2-4.1 %. Hulless oats accessions revealed unstable formation of this character over the years of research...
