Abstract
The invention discloses a method for improving paddy blast resistance by using mid-early 39. The method comprises the steps of crossing a paddy variety mid-early 39 carrying five blast resistance genes Pi-d2, Pid3, Pi5, Pib and Pi9 with a paddy material with blast resistance to be improved without carrying the five blast resistance genes, performing multiple times of back crossing by using the paddy material with blast resistance to be improved as a recurrent parent, performing back crossing on single plants simultaneously carrying the five blast resistance genes selected by using specific functional markers in each back crossing generation and the recurrent parent, and obtaining an improved paddy offspring material simultaneously gathering the five blast resistance genes of the mid-early 39 and having agronomic traits similar to those of the paddy material with blast resistance to be improved after multiple times of back crossing and selfing. The method fulfills the purpose of improving the blast resistance by gathering the five blast resistance genes of the mid-early 39.
Description
Technical field
The present invention relates to 5 rice blast resistance genes in a kind of utilization early entrained by 39 to improve the rice blast resistance of rice material, improve with seed selection rice blast resistance and economical character to wait to improve the similar method of rice material.
Background technology
Paddy rice is the important cereal crops of China.Rice blast is one of most serious plant disease of hazard rice, is considered to for many years first of the large disease of paddy rice three always.The rice varieties cultivating blast resisting is the most economical effective approach of the control rice blast that breeding circle is generally acknowledged always.Utilizing multiple rice blast resistance gene and being aggregated in same kind by different resistant genes is the prerequisite and the basis that make this kind obtain durable resistance.The conventional Indica Rice Cultivars that Zhong Zao39Shi China Paddy Rice Inst cultivates, was authorized in 2009 by Zhejiang Province, and 2012 by country's authorization.Regarded as by the Ministry of Agriculture and morning 39 in super hybridization rice there is good rice blast resistance, early 39 carry 5 rice blast resistance genes such as Pi-d2, Pid3, Pi5, Pib, Pi9 during the present inventor is found by molecular Biological Detection, therefore, early 39 can be used as the donor parents of rice blast resistance gene to improve the rice blast resistance of rice material.In this context, the present invention proposes a kind of 5 rice blast resistance genes such as Pi-d2, Pid3, Pi5, Pib, Pi9 carried middle morning 39 to import to the paddy rice of not carrying these 5 resistant genes simultaneously and treat in improved materials, to obtain the breeding method of the rice material of rice blast resistance improvement.
Summary of the invention
