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...

AI Technical Summary

Problems solved by technology

[0003] At present, the vast majority of high-grade and high-quality rice in the market are conventional rice varieties, but seed companies are not very interested in conventional rice varieties. The main reason is that conventional rice can be reserved for seeds, and the development and promotion benefits of seed companies are not high, and the model is single.

This not only restricts the application and promotion of conventional rice varieties, but also makes seed enterprises and breeders lack enthusiasm for breeding conventional rice varieties, leading to a vicious circle in the breeding and development of conventional rice. Therefore, how to protect the intellectual property rights of conventional rice is the development routine Bottleneck problem of rice, especially high-quality rice
