Abstract
Relevance. Currently, the most important tasks of breeding are the creation and introduction into production of new high—yielding varieties, resistant to stressful environmental conditions and with high grain quality, adapted to the conditions of the monsoon climate.The purpose of the study is to study varieties of spring soft and durum wheat of various origins according to the main economically valuable characteristics in the conditions of the Primorsky Territory.Methods. The research was conducted at FSBSI «FSC of Agricultural Biotechnology of the Far East named after A.K. Chaiki» in 2020–2022. Sixteen spring wheat varieties of various breeding origin served as the research object — six soft spring wheat varieties and ten hard spring wheat varieties. The weather conditions during the growing season of wheat differed over the years of the research (2020–2022). This allowed an objective evaluation of the breeding material for adaptability and resistance to stress factors.Results. For breeding and production, wheat varieties with high yields (more than 4.0 t/ha) have been identified: spring soft — Voronezh 18, Rima, Primorskaya 50, spring hard — Don Elegia. As a result of the correlation analysis, high positive associations were revealed between yield and productive bushiness (r = 0.95), the mass of 1000 grains (r = 0.85), the number of spikelets in the ear (r = 0.84). Aleyskaya, Khabarovsk and Primorskaya 40 varieties stood out with the highest index of protein and gluten in grain. Variety Sunny 573 was distinguished by high hardness (67.5%) and grain type (785 g/l).
