How the existing meadows may not cover the feed necessary all year, people are obligated to cultivate fodder also. Some of these plants are grown for grain, while others are grown for hay or green mass (Margineanu T., 1980, Marian F. et all 2010). Lolium multiflorum is a culture trying to expand into production due to production capacity, but also presents the disadvantage of lack of uniformity production on scythe (Marian F. et all 2009). The adaptability of a cultivar is generally defined as the genetic feature which enables the plant to give yields that are both high and stable in different environmental conditions. The result of the interaction between the cultivar and the environment is expressed in the adaptability and yield stability of that specific cultivar. (Savatti 2004). This paper aims at finding the dependence between the main production characters in variety SPRINT of Lolium multiflorum. The research was carried out in the experimental fields belonging to the Discipline Culture of grasslands and fodder plants from the Didactical Station of USAMVB Timisoara, the experience being placed on a cambic chernosem weakly gleyed soil, with salinisation in depth. In order to reach this goal, we studied variety Sprint in 2011 trying to find the influence of tiller number, tiller height and foliar surface on the weight of the plant. The experience is placed in accordance with the randomized blocks method, in three repetitions, a parcel surface is 15 m 2 . Sowing was made on October 12th 2010, with a 12.5 cm distance between rows. The results of our research show that regarding the main production characters of variety Sprint of Lolium multiflorum, performed above, we can conclude that there is a positive linear correlation between plant weight and the number of shoots per plant. There is also positive linear correlation between plant height and the length of the main shoot.  There were underlined also the linear dependence between the above main production characters.
