The four-generation (Generation 1 to Generation 4) pedigree used in this experiment. Interspecific hybridisation between B. napus and B. carinata (Generation 1) generated an unbalanced CCAB hybrid (Generation 2). An unreduced, aneuploid gamete from the CCAB hybrid combined with a reduced gamete from B. juncea to produce a near-allohexaploid hybrid (Generation 3) missing three B. napus A-genome chromosomes and two B. carinata B-genome chromosomes. The near-allohexaploid was subjected to microspore culture to produce a population of 75 microspore-derived progeny (Generation 4)
