Подарок Крыму – новый раннеспелый сорт озимой мягкой пшеницы | 'PODAROK KRYMU', NEW EARLY RIPENING VARIETY OF WINTER SOFT WHEAT

English. Creation and introduction into production new high-yielding and early ripening varieties of soft winter wheat adapted to certain weather conditions are the principal ways to increase yield and improve general harvest volumes. A properly selected variety is one of the most effective ways of achieving crop yield improvement for any farm. To realize the potential for increasing yields, it is crucial to bear in mind specific soil and climatic conditions. The aim of the research was to characterize a new variety of winter soft wheat 'Podarok Krymu' by economic and biological qualities, as well as morphological characteristics. Soil of the experimental plot - chernozems ordinary with a thick humus layer (up to 140 cm). The meteorological conditions during the years of research were quite diverse, which made it possible to evaluate the new variety by a set of economically valuable features. The studies were carried out in 2015-2019 on the experimental fields of the scientific crop rotation of the Department of Winter Wheat of State Scientific Establishment "Agricultural research center "Donskoy" (SSE "ARC "Donskoy"). The object of the research - a new variety of winter soft wheat 'Podarok Krymu'. Winter soft wheat variety 'Don 107' was used as a standard. Preceding crop - corn for grain. The accounting area of the variety test plot - 10 m©ч. Field experiments were replicated six times. In 2019, variety 'Podarok Krymu' was submitted for State Variety Testing by SSE "ARC "Donskoy" together with the Research Institute of Agriculture of Crimea. This variety has a high potential for grain productivity. The average yield in the competitive variety testing was 7.71 t/ha (preceding crop - corn for grain), which is 0.39 t/ha higher than the average yield of standard variety 'Don 107'. According to the length of the growing season, the variety belongs to the early maturing group; its ears emerge and kernels ripe three days earlier than that of the standard. The high and stable yield of the new variety is ensured by its tolerance to drought and heat, increased winter hardiness and resistance of plants to frost, as well as resistance to the main diseases typical in the regions where studies are being conducted. Since the autumn of 2020, 'Podarok Krymu' has been studied to cultivate it in the North Caucasian, Lower Volga and Central Black Earth regions of the Russian Federation
