Out of 71 selections of wild emmer wheat which were involved in this study on the inheritance of resistance to yellow rust, 45 selections gave conclusive results. The most common finding was that the observed segregation ratios in the F2-progenies indicated that the resistance is based on one or more dominant genes (67%). Less frequently, resistance may be conferred by one or more recessive genes (18%), or a combination of both dominant and recessive genes (15%). At least eight different genes have to be involved in the 45 wild emmer selections in order to account for our findings. © 1989 Koninklijke Nederlandse Planteziektenkundige Vereniging.
