THE STUDY OF THE COLLECTIBLE MATERIAL OF THE PSATHYROSTACHYS JUNCEA (Psathyrostachys junceus (Fish.) Nevski.) IN THE CONDITIONS OF NORTHERN KAZAKHSTAN

Abstract

This article presents the results of the study in a collection nursery in the conditions of Northern Kazakhstan of 99 samples of the Psathyrostachys juncea (wild rye), of various ecological and geographical origin, from various countries of the world: Kazakhstan, Russia, CIS countries, as well as China, Mongolia, Canada, USA, Afghanistan. The research was carried out in Akmola region in the “Scientifc and Production Center of Grain Farming named after A.I. Barayev” LLP. The samples of the Psathyrostachys juncea were studied according to agronomic characters: height, pasture mass yield, dry matter yield, seed yield, regrowth intensity after mowing, resistance to diseases and pests, plant development capacity, drought resistance, winter hardiness and feed quality (content of crude protein and crude fiber). On average, for two years of study, according to the main limiting features of the region, 25 samples of the Psathyrostachys juncea (wild rye) were isolated, which exceeded the Shortandinsky standard (75.9 g/m2 and 25.8 g/m2, 2.4 g/m2) in terms of pasture mass yield, by 6.1 - 104.9%, in terms of dry matter yield by 6.2 – 105.0%, in terms of seed yield by 4.2-158.3%. As a result of the study in the collection nursery of the Psathyrostachys juncea, 25 samples of various agronomic characters, possessing valuable signs and properties, which will later be used in breeding when creating varieties of the Psathyrostachys juncea, were identified according to the complex of economically valuable features. The scope of using the results is crop production, selection.
