Abstract:

To develop valid methods of DNA extraction for Chinese wolfberry for RAMP analysis and research. The result showed that: ten primers were applied to amplification. A total of 87 DNA bands were detected. 53 bands among which were polymorphic. The rate of polymorphic bands was 33.3%-81.9%. 10 Chinese wolfberry cultivars genetic distances were from 0.1111 to 0.8333. In the study, the RAMP markers can be used for the studies of fingerprint of Chinese wolfberry sensitively.
