Experiments have been conducted at the Rimski Sancevi experimental field (near Novi Sad, Serbia, Yugoslavia) under two sowing conditions, high density and sowing in hills. Twelve alfalfa varieties have been tested for total forage yield and dry matter yield. Of the 12 varieties tested, 9 were commercial varieties and 3 were in official trials. Seven varieties were domestic (Yugoslav) and 5 were foreign, The hybrid Ladak had the largest number of stems. The variety NS Slavija was tallest. The variety K-1 had the highest dry matter percentage. The variety NS Slavija had the highest dry matter yield in the three-year trials. Yields of green forage and dry matter are most important quantitative characteristics in alfalfa. Alfalfa yield is considerably dependent on environmental factors and breeding success is difficult to predict. Characters under study included yield performance and other characteristics that contribute to yield level. The obtained values for the components of dry matter yield served to select plants with tall and numerous stems. These will be used for further breeding. This procedure had been used when developing the three synthetic, which are presently in official trials.
