The program caters for tetraploids, hexaploids and octoploids. The methods are illustrated using data from a study of the inheritance of isoenzymes in selfed progeny of octoploid strawberry cultivars.

The Impact The study indicates that octoploids represent a unique combination of genetic variation that has helped switchgrass thrive in new environments.

Comparative analyses demonstrated that centromere length and satellite abundance significantly expanded in both wild and cultivated octoploids compared to their diploid ancestor, F. vesca.

Breeders began propagating these octoploids around 300 years ago. Since then, they have been used around the world to further enhance variety development.
