Description
A new strategic concept for breeding tetraploids of Lolium has been developed and successfully implemented for the first time. Based on a set of genetically diverse diploids a high number of tetraploids were induced with colchicine. The expression of a quantitative trait in the tetraploids behaved predictably in being dependent Upon the expression of the trait in the diploid ancestor and its heritability. The practical implementation of this rule resulted in new tetraploid strains with increases ln dry matter yield of about 1S% when diploid ancestors with high dry matter contents were used for polyploidisation.
