Last modified: 2017-04-19
Abstract
Varietal resources of forage crops in Ukraine are presented by 419 varieties and hybrids of 83 species included in the State Register for 2016. The most varieties (76%) are created by Ukrainian breeders. In recent years, there is strengthened breeding forage crops for drought resistance, expanded their species composition. Use of local wild populations of Ukraine is effective. There are created and included in to the State Register the varieties of tall oatgrass Drongo; intermediate wheatgrass Hors, Vitas; crested wheatgrass Petrovsky, Kimburn, Zhavoronok, Yastrubinovskyi; meadow brome Bojan; slender wheatgrass Columb; fine-leaf sheep fescue Barva. The varieties of crested wheatgrass Globinskiy; intermediate wheatgrass Diros and Rostislav; slender wheatgrass Zlatoslava; striated fescue Skifska are passing the qualifying examination. A promising starting material for breeding of drought-resistant species of grasses is highlighted – Psathyrostachys juncea and koehleria furrowed. Use of Transcaucasian sainfoin varieties Adam and Blisk is promising. Among the annual species, deserves special attention the variety of Pannonian vetch (winter) Orlan.
