Genomic and Genetic Studies of Cultivated Actinidia (Actinidia spp.)

Actinidia Lindl. is a genus of plants, some species of which are of great economic importance. Varieties of large-fruited Actinidia, known as kiwi (A. deliciosa and A. chinensis), are widely distributed on the world market, however, recently attempts have been made to domesticate small-fruited Actinidia, which in Russia are represented by several far-eastern species. The genomics and genetics of Actinidia are developing in different directions, often in accordance with the needs of breeders. The review describes genomic and genetic studies related to the most important agricultural traits of Actinidia: genetic diversity, chemical composition of fruits, sex coding, response to frost, storage, and transportation of crops.
