Fine mapping of the gene Rfp1 in rye and development of a physikal map to identify candidate gene sequences
Project
Project code: JKI-ZL-08-1112
Contract period: 01.01.2012
- 31.12.2015
Purpose of research: Applied research
Cytoplasmic male sterility represents a genetic mechanism of fertilization control and represents the basis for hybrid breeding in rye. An efficient restoration of male fertility is achieved by the expression of restorer genes like Rfp1. An optimized pollen shedding by means of restorer genes is currently the only approach to minimize ergot infection of modern hybrid rye varieties. However, the transfer of Rfp1 from genetic resources into elite germplasm was accompanied by a significant linkage drag due to linked genes increasing, for instance, plant height. The project aims at the development of perfect markers representing Rfp1 at the sequence level, which will allow to force the gene complex of the Rfp1 locus open by means of naturally but randomly occuring recombination. The markers will allow a novel evaluation of Rfp1 with respect to yield reducing effects.
