6. Conclusions

Оглавление

Molecular maps, databases and the first draft of the kiwifruit genome (Huang et al., 2013) have created data amenable to be validated with other techniques, mainly genetic transformation protocols. This set of tools is allowing the detailed analysis of many and very different aspects of kiwifruit biology. The analyses range from taxonomy to several aspects related to floral biology, fruit quality, delivery of new cultivars and resistance to new challenging pathogens. Other aspects of the biotechnology of this crop remain to be improved. Critical technologies such as somatic embryogenesis remain unexplored. New and promising genomic edition technologies such as TALEN’s or CRISPR-Cas will probably stimulate new research and discovery in the field of plant regeneration from protoplasts.

Oliveira and Fraser (2005) stated that the introduction into the market of new cultivars of Actinidia, e.g. Zespri® Gold, would lead to the end of the ‘Hayward’ monoculture. Bacterial canker caused by Psa can delay the development and release of new cultivars, although biotechnology will be poised to address this and other issues.
