Introduction of genes into wheat and oilseed rape from related species

Introduction of genes into wheat and oilseed rape from related species


Context and Issues

Genetic variability available in breeding is limited for some traits of wheat and oil seed rape. To overcome that limitation, transfer of genetic information from related species is the most appropriated method as far as the variation is large in those species. 

Genes of interest may be present in the diploid progenitors of oilseed rape [B. rapa & B. oleracea] and bread wheat [T. urartu, Ae. speltoides, Ae. tauschii]. Transfer of these genes is mediated through homologous recombination. On the other hand, exploitation of more distant species may be laborious and unsuccessful since their genomes are homoeologous to those of the cultivated species and since events of homoeologous recombination in the interspecific hybrids and their progenies occur with a low frequency. 

Achieved introgressions are far from being all utilisable by breeders. They may carry a huge amount of alien information and consequently carry genes with deleterious effect. If so, length of alien chromosomal segments has to be reduced. 

Resistance to diseases is the major field of research in our unit and so we mainly focus our work on this trait. 


Introduction of new resistance genes from related species into oilseed rape and wheat. 


In oilseed rape: 

transfers of specific resistances to blackleg caused by Leptosphaeria maculans from black mustard (Rlm10), brown mustard (Rlm6) and turnip (Rlm1, 7, 11)

In wheat: 

  • Optimal localization of an alien introgression : long arm 1RS of rye
  • Exploitation of the genetic variability carried by the progenitor Aegilops tauschii, in bread wheat breeding

Transfer of the HMW glutenin locus on 1D of bread wheat onto 1A of durum wheat.

Main Results

In oilseed rape:

  • Introduction of Rlm10 and Rlm6 from black and brown mustards using homoeologous recombination
  • Introduction of Rlm1, 7, 11 in oilseed rape from turnip through homologous recombination.

In wheat

  • Development of translocations 1AS-1RL, 1AL-1RS, 1BL-1RS et 1BS-1RL
  • Development of durum lines carrying the glutenin sub-unit 2-12 on the chromosome 1A.

Development of a prebreeding population and of  AB-QTL populations derived from crosses between synthetic wheats and Elite wheats.
