The new highly productive middle-early spring common wheat variety ‘Tarskaya yubileinaya’

The study of breeding material was carried out at two points of the Federal State Budgetary Scientific Institution "Omsk ARC", namely the department of northern agriculture, located in the subtaiga zone and on the experimental fields of the seed production department in the forest-steppe zone of the Omsk region. The weather conditions and soils of the experimental plots varied in temperature, precipitation, and soil fertility during the testing years. Field trials were carried out in 2017–2022 to identify highly productive spring common wheat varieties that have a complex of adaptively valuable properties and traits for cultivation in the subtaiga and forest-steppe zones of the Omsk region. As a result of breeding work, there has been developed the variety 'Tarskaya Yubileinaya' (Lutescens 70/06-4), characterized by a complex of economically valuable traits. In 2019 the variety was sent to the State Variety Testing, and in 2023 it was included in the State List of Breeding Achievements of the Russian Federation. The variety is middle-early with the vegetation period of 86 days and highly productive with a mean productivity of 4.41 t/ha through the years of study and the maximum of 6.09 t/ha that exceeds the yields of the standard variety 'Pamyati Azieva' by 1.26 t/ha (НСР05 = 0.35 t/ha). There has been established that the variety 'Tarskaya Yubileinaya' has high potential productivity due to the optimal combination of the yield elements ('number of grains per ear', '1000-grain weight', 'number of productive stems'), and has high lodging and drought resistance. There have been established the parameters of the ecological adaptability of the new variety (linear regression coefficient bi = 1.39, stability indicator (σd 2 = 0.21). The variety has shown high yield at the SVU of the Omsk Region and the Krasnoyarsk Territory. The main components of the commercial value of the variety 'Tarskaya Yubileinaya' are high and stable productivity, resistance to leaf diseases and grain quality at the level of valuable wheat.
