Abstract

This project will employ crosses with cv Brazilia with seven potential donors of improved seed dormancy (for which F2 seed is already available) and a doubled haploig (DH) population produced at JIC segregating for a new major gene (Phs) for increased dormancy. DH production of the Brazilian populations in year one will complement RFLP, AFLP and SSR mapping for a total QTL analysis of the UK population and to obtain markers closely linked to Phs. QTL mapping in the Brazilian populations, together with assessment of dormancy in the PHS chamber at JIC, will be carried out in year 2 and early part of year 3. The result will be the most comprehensive QTL study of dormancy in wheat, which will be aligned, using bioinformatic approaches being developed by the JIC Bioinformatics Group, with the available data elsewhere in wheat, in barley, in maize and in rice. It is very possible that tentative identification of candidate homoeologous genes for the wheat QTLs will be able to be made from inspection of the corresponding locations in other major cereals. The possibility of extended active collaboration with EMBRAPA will also be pursued by obtaining local phenotypic scores for the same mapping populations, as part of a theirG x Ethat analysis.
