Variety traits
Malus domestica (Suckow) Borkh.
A genetic parameter of the apple tree determined by the number of chromosome sets in cells, where the diploid set is 2n=34 and the triploid set is 2n=51. Ploidy directly influences yield, fruit weight, storage quality, and the regularity of bearing.
In the reference 479 varieties crop Apple, where this is mentioned in the description.
To determine the ploidy of apple trees, a cytological method of direct chromosome counting in vegetative bud meristems is used. In breeding, three main groups of cultivars are distinguished: diploids (2x), triploids (3x), and tetraploids (4x). The diploid chromosome number in apple trees is 34, while the triploid reaches 51 chromosomes.
Triploid apple cultivars are characterized by higher and more regular yields, reducing the alternate bearing typical of diploids. Triploid fruits usually have greater weight, better flavor, and improved storage quality. Furthermore, triploid trees often demonstrate greater vigor and enhanced self-fertility, while the breeding of such cultivars is often focused on combining fruit quality with resistance to apple scab.
