As to blueberries, I'm afraid there doesn't seem to be a single answer - evidently members of the genus Vaccinium (including blueberries, section Cyanococcus) tend to have a high inciudence of polyploidy, including natural diploid, tetraploid and hexaploid species. The book says "multiplication of the basic chromosome number" seems to have occurred frequently with hybrids.

If you are comparing size, the book stated that the blueberry DNA complement is larger than that of oranges.
Most species of oranges, including Jaffa and mandarin oranges, have 18 chromosomes. (see: http://web2.sbg.org.br/gmb/edicoesanteriores/v20n3...
