Nineteen from the ca. 30 Diplotaxis species including all known haploid chromosome numbers have been analysed for isoelectric focusing patterns of Rubisco, allozymes and RAPDs. D. erucoides (n=7) was clearly separated from all other species as were D. harra and D. crassifolia (n=13 each). Taxa with n=8 had different IEF patterns, but allozyme data grouped D. siettiana, D. ibicensis and D. brevisiliqua together. Species with n=9 were characterised by different IEF patterns, and their position was neither resolved in the allozyme nor in the RAPD tree. Only the D. catholica accessions were strongly clustered together. D. viminea and D. siifolia (both n=10) were kept separate, whereas the n=11 taxa D. tenuifolia, D. cretacea and D. simplex grouped together. Data confirm D. viminea as maternal parent of the allotetraploid D. muralis, and D. tenuifolia as the likely parent.
