We have searched for chromosome interchanges and inversions among progeny of accessions crossed with cultivars of standard chromosome structure. We make the cross-pollinations and examine the F1 plants for fertility/sterility (Delannay et al., 1982; Palmer et al., 1987). If sterility is present, meiocytes are examined to confirm the presence of a chromosome aberration.
