Variety traits

Apple Ploidy

Malus Mill.

Characteristic of the number of chromosome sets in apple cells, where the base number is x=17, with diploid (2n=34) and triploid (2n=51) forms predominating in cultivation.

In the reference 23 varieties crop Apple, where this is mentioned in the description.

In domestic apples, the main forms are diploids and triploids. Triploid cultivars are distinguished by larger fruit, improved taste qualities, and regular bearing; however, they are often characterized by vigorous tree growth, which complicates agrotechnical operations.

Due to pollen sterility or low fertility, triploid cultivars require the mandatory presence of pollinator cultivars in the orchard, which are provided by diploid forms. Methods used to determine ploidy levels include direct chromosome counting in meristems and flow cytometry.
