Sažetak
The genus Festuca is one of the largest genera within the grass family [1]. It is characterized by a complex taxonomy resulting from morphological complexity which includes not only heteromorphism but also convergent morphology of different species inhabiting similar environments. Additional taxonomical confusion is caused by the fact that some species include populations with different degrees of ploidy, resulting in varied morphological characteristics [2]. A different degree of ploidy within the same species may cause a higher ecological adaptability [3]. The aim of our research is to determine the genome size and ploidy degree in Festuca bosniaca that is native to the high mountains of the Balkans. Chromosome number in diploids of the species is 2n=14. Thirty-seven populations of F. bosniaca were sampled across its distribution range during the summer months from 2018 to 2020. On average, five individuals were sampled in each population. Genome size measured by flow cytometry showed that in sampled populations, diploids (27 populations) and tetraploids (10 populations) are found. Relative genome size ranged from 1.138 to 1.637 for diploid and 2.255 to 2.627 for tetraploid populations. Diploid populations were found throughout the whole area of species distribution, while tetraploids are limited to the central part of the range, and probably represent relicts from former glacial refugia.
