Abstract
We plan to locate and study the genetic effects of the gene(s) that control chromosome pairing in the natural amphidiploid species, Brassica napus (oilseed rape). Like most stable allopolypoids, B. napus restricts pairing and recombination to homologous chromosomes while homoeologous pairing is rare. In resynthesised B napus (used for introgressing genes of commercial importance into rape) in contrast, homoelogous pairing is common and causes problems with gamete formation and fitness. We intend to use doubled haploid lines from a cross between natural and resynthesised napus to study the pairing control. We will use molecular cytogenetic techniques (FISH, GISH) and marker genes to locate and analyse the genes concerned.
