In citrus, tetraploid plants can be apomixiss as an alternative for the diversification of rootstocks, since they present a greater genetic variability due to the new possibilities of recombination, besides being able to be used as dwarf rootstocks Cameron and Frost, ; Lee,since the new selections of rootstocks should confer productivity and quality to the fruit of the scion, be tolerant to the main plagues and diseases of the culture, and also induce plant size reduction Gonzatto et al.

Biotype and species formation. From the endocarp, string-like “hairs” extend into the locules, which provide nourishment to the fruit as it develops.

The ploidy level of these plants was confirmed by chromosome count in somatic cells of root tips according to the methodology described by Dahmer et al.
