Abstract:

A process for the production of high purity hybrid Brassica seed, comprising (a) selecting a heterozygous, maximally self-incompatible parent plant, (b) cloning said selected plant to produce a first cloned parental line, the plants of which are both maximally self-incompatible and maximally clonal-incompatible, (c) crossing plants of said parental line with plants of a second parental line, and (d) collecting high purity hybrid seed from said first cloned parental line. The second parental line may also have been obtained by cloning a second maximally self-incompatible plant to obtain a second cloned parental line, the plants of which are both maximally self-incompatible and maximally clonal-incompatible. The second parent plant may be homozygous or heterozygous. The high purity hybrid seed may be collected from said second maximally self-incompatible cloned parental line or alternatively from both first and second maximally self-incompatible cloned parental lines.
