Abstract: 
About 7200 ha of farm lands in Qom Province is cultivated to alfalfa, and about 60 percent of the lands have salinity problems. Therefore, it is neccessary to indentify the most salt tolerant alfalfa cultivars for higher forage production under these conditions. Consequently, an experiment was carried out with five alfalfa cultivars (Hamadani, Yazdi, Bami, Rahnani and Seriver) and three replications in three farms in Qomrood area with water salinities of 5, 7 and 10.5 dS/m, and soil surface salinities of 7.4, 9.2 and 13.4 dS/m. The experimental design was RCBD. Due to high salinity of soil and water in the third farm, none of the alfalfa cultivars germinated . The results showed that there were significant differences between alfalfa cultivars in the yield and quality of forage and morphological characteristices. Also, the results of combined analysis showed that the effect of year was significant. In Kashipoor Farm maximum average yield of fresh forage and dry matter were, respectively, 57.8 and 17.1 t/ha in 1999. In Abedini Farm, the maximum fresh yields were 44.2 and 43.1 for 1999 and 2000, respectively. Among alfalfa cultivars, Yazdi and Hamadani cultivars were the superior cultivars, and produced the highest fresh and dry forage yields at both farms. Therefor they can be recommended as suitable cultivars for Qom Province.
