摘要
Asian germplasm has significantly contributed to berry crops in America in several ways. The American wild octoploid species [Fragaria chiloensis (L.) Mill. and F. virginiana Mill.], and subsequently, the cultivated strawberry (F. x ananassa Duch. ex Rozier), have benefitted from Asian heritage in the evolutionary time scale. Second, breeders have combined Asian germplasm in crosses for improved fruit cultivars. Third, Asian temperate fruit species have been collected from wild stands in their native ranges, imported, and in some cases improved and are now cultivated in the West or throughout the world. The objectives of this article were to 1) describe evolutionary contributions of Asian species to the American strawberry genome; 2) present examples of breeding Asian species (Rubus L. subgenus Idaeobatus) into cultivated raspberries; and 3) give examples of two Asian fruit species that have been recently introduced and cultivated or that could be developed for cultivation in the United States.
