Abstract
The Sicilian wild tetraploid oat Arena insularis is a close relative of A. magna and A. murphyi and is more plausible than either of these two species as the immediate tetraploid ancestor of A. sterilis and the other hexaploid oats. This report presents the C-banding karyotype of A. insularis. As in A. magna and A. murphyi, the chromosomal complement can be divided into two groups, one predominantly heterochromatic and the other predominantly euchromatic. The heterochromatic chromosome group of A. insularis consists of three pairs of metacentric and four pairs of submetacentric chromosomes. The euchromatic chromosome group consists of one pair of metacentric, five pairs of submetacentric, and one pair of subtelocentric chromosomes.
