USE OF KIWIFRUIT GERMPLASM RESOURCES FOR GENETIC IMPROVEMENT
Genetic diversity provides the cornerstone for kiwifruit plant improvement. The genus Actinidia is very diverse, containing nearly 60 species, which are native to East Asia, with the centre of diversity in southern China. The recent domestication and commercialisation of kiwifruit during the past century has meant there is little difference between commercial cultivars and some of the wild germplasm. The characterisation and reproductive biology of Actinidia germplasm is described. The genetic diversity of germplasm resources and ploidy races is discussed, along with recent breeding efforts to introgress traits from related Actinidia species into commercial species. Examples of the use of Actinidia germplasm for research into kiwifruit genomics and biotechnology are given (e.g., colour expression) in relation to their potential uses for genetic improvement.
