Raspberry Breeding

摘要

Raspberries have been gathered since the beginnings of history and have been carried to temperate regions worldwide from their Eurasian place of origin. In the last two hundred years deliberate attempts to produce improved types were considerably accelerated as an understanding of reproductive biology was gained and crosses and formal breeding programs were initiated. Initial breeding utilised selections from Europe and North America, resulting in great improvements. These have been focused and expanded with the development of primocane fruiting types and through the use of other Rubus and subgenus Idaeobatus accessions for breeding. The advents of specialised tools and techniques to assess plant material, to examine their genetic structure and inheritance and even to modify the plant genome have also made a major contribution to the present range of new cultivars. This review gives an overview of raspberry genetic resources, environmental and pest and disease challenges encountered in raspberry cultivation, specialised techniques used in the development of new genotypes and propagation of the elite new cultivars. The best is yet to come!
