The article presents the overview on comparison and evaluation of Festulolium (x Festulolium) and hybrid ryegrass (Lolium x boucheanum) with in Latvia developed tetraploid pasture ryegrass variety 'Spidola'. One of the main aims of festulolium breeding is a possibility it's to used in regions where climatic conditions are not insufficient favourable for ryegrass cultivation. In Latvia, the tetraploid variety 'Saikava' that is the hybrid of pasture ryegrass, lolium multiflorum and meadow fescue has been developed at the Research Institute of Agriculture of Latvia University of Agriculture. Foreign varieties ('Punia' (L.multifloflorum x F.pratensis), 'Perun' (L.multifloflorum x F.pratensis), 'Felina' and 'Hykor' (L.multifloflorum x F.arundinacea), 'Lofa', 'Tapirus' and 'Ligunda') are also tested in conditions of Latvia as well as winter hardiness and crop yield is evaluated. The experimental data about winter hardiness and dry matter yield of sward varieties are displayed in figures 1 and 2.
