Embodiment 1

[0028] S1. 1,000 dry seeds of indica rice varieties (japonica rice varieties can be treated in the same way) were carried on the "Shenzhou VIII" spacecraft from November 1 to 17, 2011, and were in orbit for 17 days at an orbital altitude of 175-320 kilometers.

[0029] S2. After the spaceship returned to the ground, 1000 dry seeds were recovered, and all the recovered dry seeds were soaked and accelerated to germination, and then sowed into seedling trays of specific specifications. The distance between grains was 5cm (front, back, left, right). Management until the plants mature.

[0030] S3. At the maturity stage of rice plants, one rice ear is harvested from each single plant.

[0031] S4. Take 5 seeds from the specific part of the rice ear, which are: 1 grain of the first primary branch, 1 grain of the second primary branch, 1 grain of the third primary branch, 1 grain of the fourth primary branch grains, and 1 grain for the fifth primary branch.

[0032] S5. All the ear...

Abstract

The invention discloses a method for planting and harvesting offspring induced by space mutation of rice, which belongs to the field of agricultural technology. The present invention aims at the traditional physical and chemical mutagenesis techniques, first harvesting all the seeds of the 1st generation of mutagenized plants, and then randomly selecting them to form the 2nd generation of mutagenized populations, resulting in a large workload, strong randomness, and the problem of a large number of mutated genes being abandoned. A method for planting and harvesting rice space-induced offspring was proposed. The present invention soaks all dry seeds after spatial mutagenesis and sows them after germination acceleration, uses close planting to control tillering, and only harvests seeds at specific parts of rice spikes in the mature stage to form a 2nd generation population of mutagenesis, thereby improving the treatment efficiency of mutagenized progeny. Compared with the current mutagenesis progeny treatment technology, the invention reduces the workload, avoids the abandonment of some mutant genotypes to a certain extent, and improves the selection efficiency of mutagenesis breeding.

Description

technical field [0001] The invention relates to a rice breeding method, in particular to a method for planting and harvesting offspring induced by space mutation of rice. Background technique [0002] Rice is an important crop in my country, and its breeding work has received extensive attention. The mutation breeding of rice is one of the important methods to promote the progress of rice breeding in my country for half a century. Mutation breeding refers to the method of using various physical and chemical factors to induce variation and then cultivating new varieties through selection. Compared with conventional rice breeding methods, mutagenesis has the characteristics of simple method, short breeding cycle, and good effect. It has played a huge role in improving crop varieties and creating new germplasm, especially in combination with hybrid breeding technology and modern biotechnology. Combined, the breeding effect is more significant. Traditional mutagenesis methods...
