Clones of ecotypes were collected in habitats of small anthropogenical influence. Preliminary selection was done during choosing the interesting samples on a meadow. Ecotypes were set in 10 repetitions in Elizówka near Lublin. Studies were carried out in 1989-1991 taking into account the following traits: green mass yield, number of vegetative and generative shoots, plant's height, florescence length and term, length and width of basal and flag leaf, overwintering and disease infection. The two latter traits were evaluated in the last year of studies according to 9° grade. Crops of the three cuts were gathered from every 10 clusters for given ecotype; biometric measurements were made in 5 repetitions using 5 clusters of given ecotype. Results were statistically elaborated. On a basis of studies, it was found that collected material was significantly differentiated as regarding to traits under study. Number of shoots and yielding were characterised by the highest variability coefficients, and they were significantly correlated elements. The florescence term was distinguished by the lowest variability coefficient. Ecotypes collected could be the valuable material for breeding.
