Abstract

The invention relates to a grafting and seed multiplication method for saving endangered tobacco genetic resources and belongs to agriculture seed multiplication technologies and the field of genetic resources seed multiplication. The seed multiplication method includes the steps of carrying out seed cleaning on a tobacco genetic bank, listing various tobacco genetic resources with seed storage amount smaller than 3g, screening out the genetic resources which are high in death rate because of infection of root stock diseases like blackleg and bacterial wilt in seed multiplication processes over the years, adopting varieties resistant to the tobacco root stock diseases as stocks, adopting susceptible genetic resources as cions for grafting, receiving seeds of cion varieties and storing the seeds. The grafting and seed multiplication method is simple, capital and manual investment is little, the genetic resources can be effectively prevented from becoming extinct and bad influences and damage to the environment cannot be caused.

Description

technical field

[0001] The invention relates to a grafting and multiplication method for saving endangered tobacco germplasm resources, which belongs to the fields of agricultural seed multiplication technology and germplasm resources multiplication. Background technique

[0002] Tobacco germplasm resources contain extremely rich genetic genes and biodiversity, which is the key to preventing the occurrence of diseases and ensuring the sustainable development of tobacco agriculture, as well as the material basis for tobacco breeding and biotechnology research. In 2005, when Yunnan Tobacco Genebank was cleaned up, it was found that the seed storage capacity of some germplasm resources was less than 10g, and some seed storage capacity was even less than 3g. Since 2006, seed propagation and storage work has been arranged in the field year by year to supplement the seed storage capacity of the gene bank and ensure the continuous supply and utilization of germ plasm resources.
