Résumé
The widely divergent species 4xTrifolium ambiguum and 2xT.occidentale are inter-fertile long after speciation (including polyploidisation) has occurred. Tri-species hybrids (T. repens × T. ambiguum × T. occidentale) have the potential to achieve introgression of stress resistant traits from both wild species into white clover. Trifolium ambiguum and T. occidentale are geographically, adaptionally and phenotypically contrasting species in the white clover section (Trifoliastrum) of the genus. T. ambiguum occurs as a high-altitude polyploid series (2x, 4x, 6x) in W Asia and NE Europe. T. occidentale is a diploid coastal species, occurring at sea level in W Europe. This study investigated hybridisation between 4xT. ambiguum and 2xT. occidentale and considered the significance of the hybrids for introgression breeding of white clover. Partially fertile F
