This study evaluated the growth performance and productive potential of smooth meadow-grass genotypes under the pedoclimatic conditions of western Romania. The local populations were analyzed from which 20 genotypes were selected, evaluated based on morphological and productive characters, such as bush diameter, plant height, number of generative shoots, leaf area and green mass per clone. Pearson correlation analysis revealed very strong positive relationships between green mass, bush diameter and number of generative shoots, underlining the importance of these
characters in determining biomass production. Principal component analysis (PCA) and cluster analysis revealed the existence of significant phenotypic variability between genotypes and allowed the identification of groups with different levels of productivity. Overall, the results demonstrate that environmental conditions strongly influence vegetative development and the expression of productive characters, highlighting at the same time the potential for selection of valuable genotypes for Poa pratensis breeding programs.
