RESUMEN
Collected and preserved germplasm resource of Dendrobium chrysotoxum to lay the foundation for screening fine germplasm. Through refering literatures, visiting and field survey to investigate the distribution, botanic characters and apply status of D. chrysotoxum, furthermore to collect the germplasm resource. The result show that wild germplasm resource of D. chrysotoxum has obvious differences in stem characters, leaf shape as well as flower color aspects. In addition, in recent ten years, the reserves of D. chrysotoxum germplasm resource seriously descended. Through this study, we can draw a conclusion that D. chrysotoxum germplasm resource exist diversity in biology. In these germplasm resource, there are high yield and good quality variety.
