In the following paper we present the behavior of foreign genotypes of Lolium perenne (perennial ryegrass), namely EMINENT, CALIBRA and LEIA, in conditions of Timisoara, in the perspective of enriching the current assortment of fodder plants varieties. We have studied thebiometric indicators such as: length of vegetative and generative shoots, the number of vegetative and generative shoots, and the number of green leaves /vegetative and generative shoot, weight of a shrub and leaf area/shoot. Following analysis of data obtained, it can be observed that theCALIBRA variety recorded the best results, being superior front of LEIA and EMINENT varieties, in terms of vigor and ability to synthesize biomass.
