Abstract
Artificial hybrids between dysploid “chromosome races” or microspecies ofErysimum sylvestre group are produced. From the meiotic behaviour it is inferred thatE. montosicolum (n = 14) is an autopolyploid ofE. australe (n = 7) and that the Italian race with n = 11 is probably derived from an unknown tetraploid.
