Abstract: 

Mountain rye (Secal montanum) is one of the most important forage grasses for pasture establishments. It grows for grazing and hay production in the north and west mountains of Iran. In order to determine the best population for pasture establishment in Lorestan province, Iran, 10 ecotypes of mountain rye, were evaluated for seed yield, and its components. Two separate experiments were conducted under optimum and drought stress conditions using complete block design with three replications in Brojerd Agriculture Research Station, during 2003-2004. The data were collected and analyzed for flag leaf length, stem height, spike length, spike number per plant, peduncle length, seeds number per spike, forage dry matter yield, seed yield, 1000 seeds weight, harvest index, date of spike emergence and date of pollination for each environment and combined over 2 environments. Results of analysis of variance showed that ecotypes 2382M with average values of 394 Kg/h had higher seed production over both environment. The ecotypes of 2382-6 and 2382-13 with average values 3.93 and 4 ton/h had higher forage dry matter production over two environments. In general, ecotype 2382-13 with an average values of 4 ton/h forage production and 382 kg/h seed production was introduced as the best varieties for pasture establishment in areas of northern Lorestan province.
