Morphobiological features of spring soft wheat middle early variety Altayskaya 85

A promising line Lutescens 1246 was obtained by hybridization of ecological distant forms (Tyumenskaya 25 × Lutescens 721) and successive individual selection in segregating population of fourth generation and selection under different environmental conditions. During complex evaluation in competitive variety trial by agronomic characters, grain quality, and disease resistance it was found that Lutescens 1246 had equal growing season and significantly exceeded the standard variety Altayskaya 70 by 0.6 t ha (+16.7%). Lutescens 1246 had field resistance to leaf and stem rust (the standard was heavily affected) and it was practically resistant to loose smut. Lutescens 1246 belongs to strong wheat based on a complex of grain quality traits. The line exceeds the standard regarding flour strength by 63 alveograph units; it forms dough with less dilution (-15 farinograph units), and surpasses the standard in gluten content (+1.1%). Lutescens 1246 was registered by the National Variety Trial of the Russian Federation as a new middle early variety Altayskaya 85. The new variety Altayskaya 85 yielded control varieties in some variety testing stations of Siberian and Ural regions. Based on these results, the new variety was included in the State Register of Breeding Achievements of the Russian Federation since 2025 with recommendation for agricultural use in West and East Siberia and Ural region as a new middle early strong wheat variety.
