Breeding method for Heijingu and light cultivation device for breeding method

Abstract

The invention provides a breeding method for Heijingu. The breeding method comprises the following steps: step 1, spring Heixiaomai 76 as a female parent and Zhoumai 18 as a male parent hybridize to obtain an A1 generation; step 2, spring Heixiaomai 76 as the female parent and Xiaoyan 6 as a male parent hybridize to obtain an A2 generation; step 3, A1 generation plants are planted; A1 is utilizedto back-cross with the Zhoumai 18; anther culture is performed on a hybrid generation A3 thereof; illumination is performed with a light cultivation device; individual plant selection is performed toobtain a germ line A3; the generation A3 is planted, and fertile individual plants are selected for self-crossing to obtain seeds A4; step 4, A2 generation plants are planted; A2 is utilized to perform first-time backcrossing with Xiaoyan 6, and individual plant selection is performed to obtain a germ line A5; the A5 generation is planted, and fertile individual plants are selected for self-crossing to obtain seeds A6; and step 5, the A4 generation and A6 generation hybridize to obtain hybrid seeds, and the hybrid seeds serve as a strain. The invention aims to provide a breeding method for Heijingu with high yield and good disease resistance and the light cultivation device for the breeding method.

Description

technical field [0001] The invention belongs to the technical field of breeding, and in particular relates to a breeding method of black gold valley and a light cultivation device thereof. Background technique [0002] Heijingu is a kind of Triticale, belonging to Poaceae, Poaceae, Triticum barley, which grows at 100 degrees east longitude and 38 degrees north latitude, and is a rare nutritional grain. According to research, the content of total flavonoids and trace elements such as calcium, iron, and zinc in Heijingu strains is dozens of times higher than that of ordinary crops. Due to our country's large population and small land area, the land area continues to decrease, and the contradiction between the supply and demand of triticale is becoming more and more prominent. To meet the ever-increasing demand for Heijingu consumption, it is necessary to increase the yield of Heijingu and enhance the disease resistance of existing Heijingu varieties. The most direct and effec...
