• • • Economical and biological traits of new varieties of perennial grasses
Assortment expansion of perennial grasses is related to creating varieties with productive longevity and sustainable adaptability to specific environmental conditions. The article presents the results of two cycles of competitive variety trial and descriptions of varieties of meadow fescue (Festuca pratensis H.) ‘Pamyati Enikeeva’ and bird’s-foot trefoil (Lotus corniculatus L.) ‘Fakel’. Plant breeding was carried out in the Bashkir Agricultural Research Institute. The variety ‘Pamyati Enikeeva’ was obtained by the open pollination of samples of local flora with the variety ‘Morshanskaya 1304’ followed by multiple selection. This variety produced 32.9 t ha-1 of green mass, 9.3 t ha-1 of air-dry matter, 484 t ha-1 of seeds, which exceeded the values of the standard ‘Morshanskaya 1304’ by 15.4, 16.1, and 11.3% respectively. Due to high drought resistance, winter hardiness, productive longevity, and resistance to grazing, the meadow fescue variety ‘Pamyati Enikeeva’ is recommended for haymaking and pasture use in steppe and forest-steppe. The variety of bird’s-foot trefoil ‘Fakel’ was bred by the multiple selections from a complex hybrid population, obtained as a result of open pollination of samples of different geographical origin. This variety produced 18.7 t ha-1 of green mass surpassing the standard ‘Smolenskiy 1’ by 12%. Its seed productivity averaged to 245 kg/ha and exceeded the standard by 19.5%. Due to high winter hardiness, productive longevity, and resistance to grazing, the new bird’s-foot trefoil variety ‘Fakel’ is recommended for developing long-term pastures and hayfields in the forest-steppe.
