Biotechnology breeding method of regenerated functional rice

Abstract

The invention discloses a biotechnology breeding method of regenerated functional rice. The method comprises the following steps of S1, selecting barnyard grass as a donor; S2, selecting Xiangwanxian No.5 as a parent body; S3, extracting DNA of the donor; S4, introducing guiding the DNA of the donor into the Xiangwanxian No.5; S5, collecting distant hybridization seeds of the Xiangwanxian No.5 in S4. By means of the biotechnology breeding method, the yield of the rice can be greatly increased, the DNA of the barnyard grass is introduced into the Xiangwanxian No.5, and the purpose that rice is harvested twice after being planted once can be achieved. The barnyard grass belongs to field weeds, has strong growth capability, and does not grow tall but grows dense. The first yield of the rice seeds cultivated by means of the method reaches 550-600 kilograms, and the yield of the regenerated rice reaches 300-400 kilograms.

Description

technical field [0001] The invention relates to a biotechnology breeding method for regenerative functional rice, belonging to the technical field of rice breeding methods. Background technique [0002] About 60% of my country's population takes rice as the staple food, so increasing rice production is a major issue for my country's sustainable agricultural development and ensuring food security. As the process of industrialization and urbanization is engulfing rice fields, to meet the challenges of population growth and ensure the steady development of the national economy, the fundamental way out is to increase the yield potential per unit area. Grain is a special strategic commodity, which is related to national economy and people's livelihood, political stability and social stability. Once there is a shortage of food and the food problem cannot be solved, economic development and social stability will lose their solid foundation. At present and for a long period of tim...

Problems solved by technology

At present and for a long period of time in the future, it is impossible to increase rice production by expanding rice planting area, and it is also very difficult to maintain the existing rice planting area due to the demand for land in other aspects. About 80% of the total increase in grain production in the future will need to come from yield increase
