A kind of breeding method of multi-flower Polygonatum multi-bud tiller variety

Abstract

The invention discloses a method for breeding Polygonatum multiflora multi-bud tiller varieties, which belongs to the technical field of plant propagation and comprises the following steps: A1, carrying out ecological investigation of Polygonatum multiflora population; A2, establishing Polygonatum multiflora germplasm resources A3. Construction of HPLC fingerprints of Polygonatum multiflora from different origins; A4. Screening of multi-bud and tiller varieties; A5. Index detection. Compared with conventional varieties, Polygonatum multiflora and multi-flower tiller varieties obtained by breeding through the breeding method of the present invention have obvious yield advantages, better stress resistance, and rich Polygonatum polysaccharide content. The present invention provides artificial cultivation of Polygonatum multiflora. The strong product quality control guarantee also provides an effective quality evaluation method for screening out germplasm resources with high polysaccharide content and good quality from Polygonatum multiflora germplasm resources nursery.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a breeding method for Polygonatum multiflora and multiflower tiller varieties. Background technique [0002] Polygonatum is known as the "Century Longevity Immortal Grass". It is one of the traditional Chinese medicinal materials announced by the National Health and Medical Commission. It is also a traditional bulk medicinal material in China. The Pharmacopoeia stipulates that only the dry rhizomes of Polygonatum kingianum, Polygonatum sibiricum and Polygonatum cyrtonema can be used as Chinese medicine Polygonatum, which are commonly called "Rhubarb Rhizome", "Chitou Polygonatum" and "Jinger Shape Polygonatum" respectively. ". Among them: the multi-flower yellow fine variety is recognized as the "best quality variety". [0003] The main producing areas of wild Polygonatum multiflora are the Wuyi Mountains in Fujian and Jiangxi provinces. The artificial cu...

Problems solved by technology

However, in the artificial planting process of traditional Polygonatum multiflora, it is common: most of the seedlings are in the state of "three noes", that is, there are no standards for production, no channels for operation, and no way for management, which is similar to "the quality of Chinese medicinal materials is uneven, The market situation does not understand the blind development, the seedlings are deceived and it is difficult to protect their rights, and the after-sales service of the seedlings is lacking” and other situations occur from time to time; traditional cultivars are single, low yield, long cycle, and serious quality degradation, etc., urgently need high-quality new varieties to update, To increase the planting benefit; the asexual reproduction coefficient is low, and the required base is very high, mainly because Polygonatum multiflora has a strong germination ability at the front 3-4 nodes, and the generated plants are relatively vigorous, but the nodes at the tail are difficult to germinate. Even if germination is successful, growth quality will suffer
