The widely divergent species 4
x
Trifolium ambiguum
and 2
x
T.
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 (2
x
, 4
x
, 6
x
) 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 4
x
T. ambiguum
and 2
x
T. occidentale
and considered the significance of the hybrids for introgression breeding of white clover. Partially fertile F
1
hybrids between 4
x
T. ambiguum
and 2
x
and 4
x
T. occidentale
were generated by embryo rescue. Hybrid plant morphology and fertility varied widely and hybrids generally expressed traits from both species. Advanced generation (F
2
–F
5
) 4
x
hybrids were highly fertile and constitute a new synthetic allotetraploid species. FISH analyses of 4
x
hybrids showed multivalent chromosome configurations with homoeologous associations between
T. ambiguum
and
T. occidentale
chromosomes. Crosses of the hybrids with
T. repens
produced fertile tri-species progeny. These very divergent species remain inter-fertile long after speciation (including polyploidisation) has occurred. Tri-species hybrids have the potential to achieve introgression of stress resistance traits from both wild species into white clover. |
