Abstract

The invention relates to a germplasm improvement method for traditional Chinese medicinal materials. The germplasm improvement method comprises the steps of A germplasm selection, B germplasm improvement, C improved germplasm identification and screening, D improved germplasm rooting, E rooted seedling domestication and F improved germplasm seed obtaining. According to the method, colchicine is used for conducting polyploid induction on ainsliaea fragrans sterile adventitious buds, then screening and purification culture are conducted through a morphological identification method and a chromosome tabletting method, the improved ainsliaea fragrans germplasm is obtained, and the obtaining rate is 19%; according to the obtained improved ainsliaea fragrans germplasm, stems are obviously thickened, leaves are obviously thickened, the single plant biomass is 1.9 times higher than that of an original female parent, the yield per mu is 1.6 times higher than that of the original female parent, meanwhile, the chlorogenic acid content is 1.3 times higher than that of the female parent, and the protocatechuic acid content is 2.2 times higher than that of the original female parent; and the obtained high-quality germplasm has genetic stability, and plants planted through the seeds still have fertility.

Description

technical field [0001] The invention relates to a method for improving germplasm of Chinese medicinal materials, which belongs to the field of plant crop breeding and planting of Chinese medicinal materials, in particular to a method for improving germplasm of apricot-scented rabbit ears. Background technique [0002] Ainsliaea fragrans Champ is a plant of the genus Ainsliaea fragrans Champ in the family Asteraceae. The whole herb is used as medicine. It has the effects of clearing away heat and detoxification, promoting dampness, and stopping bleeding. It is mainly used to treat lung abscess, mastitis, malnutrition, osteomyelitis, and snake bite hurt. Apricot rabbit ear wind is mainly distributed in Taiwan, Fujian, Zhejiang, Anhui, Jiangsu, Jiangxi, Hubei, Sichuan, Hunan, Guangdong, Guangxi, Yunnan and other provinces. In the border grass, Yunnan is also distributed near the altitude of 2000 meters. Apricot Rabbit Ear Wind contains chlorogenic acid, apigenin, quercetin, l...
