Abstract

Some plant species belonging to the Koeleria genus have many features that make it an ideal grass with low maintenance costs. Their slow growth habit, tolerance to drought and extreme environmental conditions, and their wide natural distribution make them strong candidates for development as grass and forage. In this study, observations and measurements were carried out in 2019-2020 to determine phenotypic characteristics in 53 genotypes selected according to their superior characteristics from Koeleria genotypes collected from the natural flora of Turkey. In Koeleria genotypes; Quality (1-9 scale), seasonal color change (1-9 scale), leaf texture (1-9 scale), density (1-9 scale), plant height (cm), leaf width (cm), leaf length ( cm), leaf area (cm²), growing type in autumn (1-9 scale), plant diameter (cm), spring regrowth time (1-9 scale), panicle formation tendency (1-9 scale), panicle height (cm ), last internode length (cm), seed yield (g) mean values were 6.90, 4.13, 4.01, 4.73, 52.11, 0.21, 16.15, 3.42, 3.60, 46.33, 6.54, 5.37, 7.69, 16.88, 4.7, respectively. Correlation analysis table was created among the phenotypic traits examined and it was found that the traits were significantly effective on each other. Positive correlations between some of these will allow for multi-featured selection in variety improvement. In addition, in the dendrogram created as a result of the cluster analysis, the genotypes are divided into 2 main and 2 subgroups in each main group. This analysis provides ease of selection according to the characteristics focused on these groups for synthetic variety breeding and future breeding studies. As a result of this study, the superior Koeleria genotypes that can be used in breeding studies will be determined.
