Conventional rice intellectual property protection method

Abstract

The invention relates to the technical field of rice variety cultivation, in particular to a conventional rice intellectual property protection method which comprises the following steps: transferring a protection gene of rice with the protection gene into rice with high stigma exposure, high natural outcrossing rate, general agronomic traits and excellent rice quality; selfing the progeny, and removing strains without the protection gene until homozygosis to obtain rice containing the protection gene; respectively hybridizing the bridge parent with the high-quality parent and the high-quality parent containing the protective gene to obtain a hybrid F1 and a hybrid F1 containing the protective gene; the hybrid F1 and the hybrid F1 containing the protective gene are subjected to multiple cross with the high-quality parent and the high-quality parent rice containing the protective gene respectively, and multiple cross F1 and multiple cross F1 containing the protective gene are obtained. According to the invention, the protection gene is arranged, so that seeds cannot be reserved privately, the trouble that the benefit of developing conventional rice varieties by seed enterprises is not high is solved, meanwhile, the resistance of rice is greatly improved by utilizing mixed varieties, and the eurytopic applicability of the rice varieties is enhanced.

Description

technical field

[0001] The invention relates to the technical field of rice variety cultivation, in particular to a method for conventional rice intellectual property protection. Background technique

[0002] In recent years, with the country's emphasis on rice quality and the advancement of supply-side reforms, and the improvement of people's living standards, higher requirements have been placed on rice quality. What is overlooked is that although the government, seed industry enterprises, rice processing enterprises and breeders attach great importance to rice quality, the overall quality of rice in my country is still unsatisfactory, and there are still few high-quality and high-grade rice varieties. It is an unavoidable fact. Therefore how to create high-grade high-quality rice, and then improve the rice variety rice quality of my country as a whole, is the biggest obstacle to the development of the seed industry, and is also an urgent problem to be solved in the product...

Embodiment Construction

[0028] The invention discloses a conventional rice intellectual property protection method, which will be further described in detail below through specific examples.

[0029] The conventional rice intellectual property protection method of the present embodiment comprises the following steps:

[0030] Step 1: Transfer the protective gene of the rice with the protective gene to rice with high stigma exposure, high natural outcrossing rate, average agronomic traits and excellent rice quality, and then self-cross the offspring and remove the plants without the protective gene line, until homozygous, the rice containing the protection line gene is obtained;

[0031] Step 2: cross the bridge parent with the high-quality parent and the high-quality parent containing the protective gene respectively to obtain the hybrid F1 and the hybrid F1 containing the protective gene;

[0032] Step 3: recrossing the hybrid F1 and the hybrid F1 containing the protection gene with the high-qualit...
