Embodiment Construction
[0048] The method of the present invention will be further described in detail below in conjunction with specific examples.
[0049] Tiandan No. 2 is a Danshen hybrid made by using the Danshen male sterile line SH-B-18 as the female parent and the fertile line Danshen A-107 as the male parent.
[0050] Breeding process:
[0051]Breeding of the male inbred line Danshen A-107: the inbred line Danshen A-107 is a single plant selected by systematic selection from Danshen cultivated in Datian, Shanyang County, Shangluo City in May 2003. The phenological phase, stress resistance, combining ability, quality and yield per plant were systematically analyzed. Finally, according to the comprehensive indicators, the content of danshensu, tanshinone and phenolic acids in Danshen medicinal materials were used as indicators, and the combined ability was determined to determine the selection. To ensure the stability of each index, the selected strain A-107 was finally selected as the male in...

Abstract
The invention discloses a breeding method of a novel variety of red-rooted salvia. The breeding method of the novel variety of red-rooted salvia includes using a male sterile line SH-B-18 of red-rooted salvia as a female parent and a fertile line A-107 of red-rooted salvia as a male parent, and preparing the female parent and the male parent into a hybrid of red-rooted salvia. The breeding method of the novel variety of red-rooted salvia is applicable to novel high-yield, stable-yield, high-quality, disease-resistant and highly-applicable hybrid varieties of red-rooted salvia with fine comprehensive agronomic characters, which are planted in a base of Shangluo red-rooted salvia, even in same planting areas of China, and is applicable to the technical field of breeding.
Description
technical field [0001] The invention belongs to the technical field of breeding, and relates to a method for breeding new varieties of salvia miltiorrhiza. Background technique [0002] Roots and rhizomes of Salvia miltiorrhiza. Produced in Jiangsu, Anhui, Hebei, Sichuan and other places. Excavated in spring and autumn, washed and dried in the sun. Sliced, segmented, raw or fried with wine. Bitter in the mouth, slightly cold in nature. Can promote blood circulation and remove blood stasis, cool blood, soothe the nerves. Contains tanshinone, protocatechualdehyde, protocatechuic acid, danshensu, vitamin E, etc. It can dilate coronary arteries, increase coronary flow, improve myocardial ischemia, infarction and heart function, regulate heart rhythm, expand peripheral blood vessels, improve microcirculation; improve the body's ability to withstand hypoxia; have anticoagulation, promote fibrinolysis, Inhibit platelet aggregation and thrombosis; reduce blood lipids and inhib...
