For each of these, there are various ploidy levels, ranging from diploid to octoploid and beyond.
As with other African acacias, A. tortilis is a polyploid complex most are tetraploids (2n = 4x = 52); ssp. raddiana is an octoploid
Instead of being ABDR, it doubles into an octoploid triticale,
Except for some successful octoploid primary triticales developed and used in China, secondary triticales form the basis of the world's triticale industry at this time.
At CIMMYT in the 1970s, the crop's agronomic breakthroughs came from crosses between Armadillo (a hexaploid) and some newly created octoploid triticales, of which the Maya group were among the first.
Nonetheless, some of the most valuable genetic traits are found in octoploids, and the creation of practical octoploid triticales is an important promise for the future.
These octoploid triticales were also more winter hardy, more adaptable to poor soils, and more resistant to drought and lodging.
In southwestern China, on the highlands of the Yunnan-Sichuan plateau, successful cultivation and utilization of octoploid triticale is under way.
Most of us have our genes arrayed on two chains of chromosomes, one from each parent; dahlias have eight chromosome sets, which makes them, technically speaking, octoploid.
