In t design with three replications in the two location of Karaj and Gorgan during two years (1401-1402 and1402-1403). Each plot consistedhis research, ten hybrids with control hybrid (speed feed) were investigated in the form of randomized complete block of 4 rowes along 4 meters with row spacing 60 cm and the distance of plants on the rowes was 8 cm.The results of combine variance analysis showed that the main effects of genotype, environment and interaction of genotype × environment on wet and dry forage yield and other studied traits were significant at the 1% probability level. According to the GEI model for wet forage, 63% of the total changes were related to the first main component and 20.1% of the total changes were related to the second main component, which explained 83.1% of the total changes. Based on the analysis of GEI and GGE-Biplot, the experimental environment of Karaj had good separation power in both years of the experiment and was recognized as a suitable place for selecting superior hybrids. On the Based of results in Gorgan, hybrid KHFS10 (A2xR109) was suitable for wet forage (129.5 and 126.9 tons. ha-1 in the first and second year respectively) and dry forage yeild (25.9 and 27.8 ton. ha-1 in the first and second year respectively) and areas with similar climates. KHFS3 (PegahAICS88005×) and KHFS10 (A2×R109) hybrids were suitable for wet forage and hybrid KHFS3 (Pegah×AICS88005) for dry forage (first and second year, respectively, 32.4 and 32.2 ton. ha-1) in Karaj.
