Abstract

Ph1 is the major domestication locus controlling chromosome pairing and therefore fertility in hexaploid wheat and tetraploid wheat. It is also responsible for the major control of pairing and recombination between wheat and wild relative chromosomes in interspecific hybrids. Modification of this locus would enhance the efficiency of alien introgression. The Ph1 locus has now been defined to a region of wheat chromosome 5B containing 19 genes, one (my) of which has homology to proteins involved in meiosis and chromosome structure. The present proposal aims to assess whether this is the Ph1 gene and to eliminate the other genes as candidates. The approach used to achieve this aim will also generate wheat lines exhibiting variation in the Ph1 pairing phenotype which therefore will be useful to breeding in the exploitation of genetic variation in wild germplasm.
