Variety traits
Pyrus pyrifolia (Burm. f.) Nakai var. culta (Mak.) Nakai
A qualitative characteristic reflecting the history of a cultivar's development through breeding methods, pedigree, and place of origin. It determines the biological traits of the cultivar, including winter hardiness, disease resistance, and fruit morphology.
In the reference 3 varieties crop Asian pear, where this is mentioned in the description.
The origin of a cultivar for Pyrus pyrifolia includes data on the seedling development method, parent forms, and information about the breeding institution. For the Asian pear, it is crucial to have the species Pyrus pyrifolia, Pyrus bretschneideri, and Pyrus ussuriensis in the pedigree, which determine the genetic potential.
This trait serves as a key indicator of biological properties. The involvement of Pyrus ussuriensis in the origin provides increased frost resistance down to -35 °С. The genetic lineage, for example, the Japanese or Chinese groups, predetermines fruit morphology, as well as natural immunity to a complex of diseases.
