Molecular characterisation of microspore-derived progeny from the interspecific F1 of Brassica napus × B. carinata

摘要：

We report the molecular characterisation of microspore-derived progeny from an interspecific F1 hybrid (ABCC genome) of a Brassica napus (AACC genome) × B. carinata (BBCC genome) cross using microsatellite markers with known genetic map locations on the Brassica A, B and C genomes. We observed unusual inheritance patterns of chromosomes from the A, B and C genomes with the majority of microspore-derived lines possessing chromosome complements similar to, but not the same as, the interspecific F1. We discuss possible explanations for this phenomenon including the hypothesis that these F1-like progeny are products of unreduced (2n) gametes, possibly through a mechanism of First Division Restitution.
