Actinidia is a genus of recent domestication. Initially, the kiwifruit industry was based on cultivars of A. chinensis var. deliciosa, and since 1975, ‘Hayward’ has been the dominant cultivar (Ferguson and Huang, 2007). Another important cultivar is A. chinensis var. chinensis ‘Hort16A’, known commercially as Zespri^® Gold kiwifruit (Wang and Gleave, 2012). The rapid expansion of kiwifruit cultivation has revealed the need to obtain new cultivars or domestication of new species that are better adapted to different growing conditions. A distinctive feature of the genus is the structured reticulate pattern of diploids, tetraploids, hexaploids and octoploids in diminishing frequency, associated with geographic separation of ploidy races (Ferguson and Huang, 2007). This ploidy variation between taxa and the existence of ploidy races within taxa can make crossing in Actinidia difficult. However, Li et al. (2010) observed that the type of fruit hairs, fruit flesh colour and fruit weight are related to ploidy. Therefore, breeders can obtain a large range of kiwifruits.
