Roses are among the world s most important ornamental crops. A significant number of these cultivars where developed as a result of the introduction of Chinese germplasm into Europe around the year 1800. Diseases and insect infestations in roses are numerous and are often controlled with a combination of cultural treatments and pesticides. Increasing pesticide use is leading to a great deal of concern from rose growers around the world. Since China is a major center for wild roses, it is hoped that new, novel genes can be identified from native Chinese species.
China is the center of diversity for roses.
Relatively few rose species have been used in breeding due to limited knowledge concerning taxonomic and other characteristics as well as limited access. The introduction of such species into modern rose breeding programs would be highly beneficial. In return, the team agreed to provide a series of seminars at each center we visited. Information about our different programs was outlined in slide presentations and discussions. The technical aspects of translation were greatly facilitated by Dr. Yan Ma and Mr. Ping Lim, who are both fluent in Chinese.
