Embodiment 1

[0032] A method for germplasm improvement of apricot-flavored rabbit ears, comprising the following steps,

[0033] A. Germplasm screening: select high-quality germplasm with high content of active ingredients and large biomass per plant as female parent;

[0034] B. Germplasm improvement;

[0035] B1 material cleaning: select healthy young stems free from diseases and insect pests, rinse with soapy water for 20 minutes, rinse with water 4 times, drop 2 drops of Tween-80, shake for 10 minutes, rinse with tap water for 60 minutes;

[0036] B2 Aseptic system establishment: Transfer the cleaned materials to the ultra-clean workbench, first disinfect with 75% alcohol for 10 seconds, rinse with sterile water twice, and disinfect with 2 drops of 0.1% mercury solution of Tween-80 for 6 minutes , rinsed with sterile water 6 times, absorbed the surface moisture on the sterile filter paper, removed the wounds at both ends after disinfection, cut it into 1.0cm-sized small sections with ...

Abstract

The invention relates to a method for improving germplasm of traditional Chinese medicinal materials. The steps include: A germplasm selection, B germplasm improvement, C improved germplasm identification and screening, D improved germplasm rooting, E rooted seedling domestication and F improved germplasm seeds Obtained; the present invention uses colchicine to induce polyploidy of aseptic adventitious buds of Xingxiang rabbit ear wind, and then screens and purifies the improved Xingxiang rabbit ear wind germplasm through morphological identification method and chromosome pressing method, and the acquisition rate is 19%; the improved Xingxiang rabbit ear wind germplasm obtained by the present invention has obvious thickening of stems and obvious thickening of leaves, and the biomass per plant is 1.9 times higher than that of the original female parent, and the yield per mu is 1.6 times higher than that of the original female parent , at the same time, the content of chlorogenic acid is 1.3 times higher than that of the female parent, and the content of protocatechuic acid is 2.2 times higher than that of the original female parent; the high-quality germplasm obtained by the present invention has genetic stability, and the plants planted by seeds still have the potential 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...
