Abstract
Part of the results of testing of new cultivars of perennial grasses is presented in this paper. New cultivar of English ryegrass (Lolium perenne L.) was tested, and the cultivars of Italian ryegrass (Lolium multiflorum Lam.), red fescue (Festuca rubra L.) and French ryegrass (Arrhenatherum elkatius L) were reacknowledged. Cultivars are selections of the institute of forage crops, Krusevac, and compared to standard foreign and domestic cultivars. Trial was carried out on four locations: Novi Sad, Krusevac, Zajecar and Zemun, in period 2005-2006. The following traits were monitored: clustering, resistance to flattening, enduring winter, crop density, and in the cutting period also the height of plants was determined. In four cuts the production of green and dry matter was established, and using standard laboratory methods main quality parameters were determined, content of crude cellulose, protein, fat, ashes and NFE. Results were calculated using variance analysis and testing of significance was performed using LSD test. After this test, cultivars were reacknowledged and cultivars introduced to the list of cultivars: Italian ryegrass K 13, red fescue K-14 and French ryegrass K-12, and new cultivar of English ryegrass K-11 acknowledged as the first domestic breeding of this species. Obtained results recommend new cultivars to be introduced into production in grass-leguminous mixtures and grasslands, or pure crops, to be used for cutting, or grazing, as well as for grass seed production where we lack in regard to production.

Summary
Apstrakt: U radu je prikazan deo rezultati testiranih novih sorti višegodišnjih trava. Testirana je nova sorta engleskog ljulja (Lolium perenne L.), a repriznate su sorte italijanskog ljulja, (Lolium multiflorum Lam.) crvenog vijuka (Festuca rubra L.) i francuskog ljulja (Arrhenatherum elkatius L). Sorte su selekcije Instituta za krmno bilje Kruševac, a upoređene sa standardnim stranim i domaćim sortama. Rezultati su obračunati anlizom varijanse a testiranje značajnosti utvrđeno je LSD testom. Ovim ispitivanjima repriznate su i uvedena na sortnu listu sorte italijanskog ljulja K-13, crvenog vijuka K-14 i francuskog ljulja K-12, dok je priznata nova sorta engleskog ljulja K-11, a koja je prva domaća selekcija na ovoj vrsti. Dobijeni rezultati preporučuju nove sorte za uvođenje u proizvodnju pri zasnivanju travno-leguminoznih smeša, ili čistih useva za korišćenje kosidbom, ili ispašom, kao i za proizvodnju semena trava u čijoj smo proizvodnji jako deficitarni
