Mandarin Ploidy

Citrus reticulata Blanco

Mandarin ploidy reflects the number of chromosome sets, with diploid forms (2n=18) being typical, while triploid and tetraploid forms are used in breeding to obtain seedless fruits and improve stress tolerance.

In the reference 31 varieties crop Mandarin orange, where this is mentioned in the description.

Diploidy (2n=2x=18) is the characteristic state for mandarin. Breeding programs utilize polyploid forms, such as triploids (2n=3x=27), tetraploids (2n=4x=36), and hexaploids (2n=6x=54). The ploidy level is most efficiently determined by flow cytometry, although chromosome counting in meristematic tissue cells was previously employed.

The artificial creation of tetraploid mandarin forms is used to improve abiotic resistance, particularly in developing rootstocks capable of better tolerating soil salinity and nutrient deficiencies. Triploid forms are of particular value in production, as their use allows for the obtaining of seedless fruits, which is an important commercial quality of the mandarin.
