and diploid darrow's evergreen blueberry (V. darrowii Camp) have been produced by exploiting V. darrowii's tendency to produce 2n gametes and a strong triploid block, which greatly reduces the number of triploid hybrids produced. Colchicine-derived tetraploids offer an alternative method of ...

This value has been demonstrated in breeding in many other polyploid crops (Veilleux 1985). In Ipomoea, 2n gametes have been shown to function in polyploidization from the 2x to the 3x and 4x level...Use of Ipomoea trifida germ plasm for sweet potato improvement. 3. Development of 4x ...
sinense (2n = 81–124), and S. spontaneum (2n = 40–128, x = 8) [3,4], constituting approximately 80% of S. officinarum, 10–15% of S. spontaneum, and 5–10% recombinant chromosomes [4]. Currently, all commercial sugarcane breeding populations in the world share a narrow genetic...
