[Systemic breeding of the new variety of Biantiao ginseng (Panax ginseng)]
1Department of Cultivation, Institute of Medicinal Plant Development, CAMS, PUMC, Beijing 100094, China.
Objective:
To breed new varieties of Biantiao ginseng for high yield and fine quality.
Methods:
Systemic breeding methods were applied. About 3,000 outstanding Biantiao ginseng roots were selected and planted in breeding field, and self-crossed for four generations. During the course, inferior lines or plants were rejected. Then strain comparison, identification of resistance to black-speck disease, and analysis of active compositions were carried out.
Results:
"Biantiao 1" (BT1), the first new variety of Biantiao ginseng, with green stems and thick, long, elegant roots and median resistance to black-speck disease, has been harvested since 20 years. The percentage of Biantiao ginseng roots and yield were 15% and 30% higher than the control's respectively. The content of total ginsenosides and the main monomers was 1.8%-2.5% higher than the control's. The characteristics of overground part and root of BT1 were uniform and stable.
Conclusions:
BT1, a new excellent ginseng variety, has a good potential value to be generalized in ginseng production.
