Abstract: | Seeds of the H. murinum aggregate were collected from much of the range of the group and soluble protein extracts were subject to gel-electrophoresis analysis. Diploid, tetraploid and hexaploid plants were readily differentiated. Analysis using a similarity matrix and dendrogram revealed further groups within the ploidy levels and indicated inter-group relationships. Evidence obtained supported karyological results, suggesting that tetraploid and hexaploid plants are allopolyploids, and that one of their putative parents is a diploid known from Turkey and adventive in Australia. Within the tetraploids there is little correspondence between groups detected by either gel-electrophoresis or karyology, and the species H. leporinum (mostly southern) and H. murinum (mostly northern). |
