Embodiment 1

[0020] Select 3 wheat varieties, cool and dry them and carefully store them under low temperature (0-8°C) and dry conditions for later use, about 4000 grains for each variety. When the seeds are not completely dry, fix the end containing the germ, keep the part including the wheat germ that accounts for about 1 / 3 of the seed volume, and use a knife to cut off the other parts. The edge of the knife is about 1mm away from the edge of the germ, so as not to damage the wheat germ. Finally, remove the rotten grains that do not meet the requirements. Use a single layer of ultra-thin cotton cloth and corresponding sutures for packaging, plan the size before suturing and mark the material name on the corresponding position; sew the border well to prevent confusion. Store in a dry environment at 4°C while preventing moths and mice. Seeds are spaceborne and mutagenized.

[0021] Preparation before sowing: Thorough stubble removal, watering in advance to store moisture, and proper appl...

Abstract

The invention belongs to the technical field of space breeding, in particular relates to a seed processing technology in the space breeding, and the technology includes seed selection, package, storage, space loading and mutagenicity of seed, seed culture after the space loading and mutagenicity, and seedling selection, wherein, a syncopation processing is performed after seed selection and before package: a part with an embryo occupying one third of the whole seed is reserved, and the rest parts are ablated. Through the reasonable syncopation processing for the seed, the method of the invention greatly lightens the weight of the loading seed, at the same time, reserves the vitality of the seed and reduces the loading cost; in addition, the problem that sowing cannot be performed in season is solved through improving the breeding technology of the seed after space loading and mutagenicity; thereby providing fine support for the wide range of application of the space breeding technology.

Description

(1) Technical field [0001] The invention belongs to the technical field of space breeding, and in particular relates to a seed treatment technology. (2) Background technology [0002] Space breeding is the abbreviation of space mutation breeding, also known as space breeding or space mutation breeding. It is a modern method that puts plant seeds into space vehicles, operates them in space, makes space factors interact with plant seeds, induces genetic variation in plants, and cultivates new varieties through continuous planting and selection after returning to the ground. Breeding methods. Like radiation breeding, it belongs to the category of artificially induced mutation breeding, and has the basic characteristics and attributes of artificially induced mutation breeding, such as high starting point, short cycle, and strong innovation. It has good application prospects in the breeding of new super crop varieties, crop quality improvement and stress resistance improvement....
