Abstract
Description
technical field
[0001] The new poplar mutation breeding method of the invention relates to a radiation-induced mutation method for poplar embryogenic cells, especially a new method for obtaining a large number of mutant plants through gamma-ray-induced mutation. Background technique
[0002] The research and development of tree breeding shows that the traditional method has disadvantages such as long life span and slow breeding progress. The application of high technology combined with conventional breeding methods is the main direction of current tree breeding.
[0003] Using physical and chemical factors to induce mutagenesis, select and breed excellent mutants, and cultivate them into varieties, which are widely used in variety improvement. The most important of these is to irradiate seeds or other reproductive organs with X-rays and γ-rays, but the mutation frequency after irradiation is extremely low (10 -8 -10 -5 ), so the number of processed individuals (seeds, buds...
