Description

Technical Field

[0001] This utility model relates to the field of breeding equipment technology, specifically to a breeder for breeding wheat varieties resistant to Fusarium head blight. Background Technology

[0002] Fusarium head blight is a disease of wheat caused by various Fusarium fungi. It can occur from the seedling stage to the heading stage, causing seedling rot, stem base rot, stalk rot, and ear rot, with ear rot being the most damaging. Under high humidity, a pinkish mold layer is visible on the diseased parts. Affected wheat has reduced dry grain weight, decreased germination rate, rotten and shriveled grains, low flour yield, poor flour quality, and reduced commercial value. Yield is reduced; in epidemic years, yield is generally reduced by 20-30% per mu (approximately 0.067 hectares), and in severe cases, yield can be reduced by more than 50%. Furthermore, the fungal toxins produced by Fusarium head blight have an impact on or pose a risk to human and animal food safety.

[0003] In the current process of breeding wheat varieties resistant to Fusarium head blight, wheat is inoculated with Fusarium head blight pathogens at a certain stage of growth to cause infection. Uninfected plants are then extracted as seedlings. However, Fusarium head blight can occur from the seedling stage to the flowering stage, and the resistance to Fusarium head blight varies at different growth stages. The lack of inoculation and identification of Fusarium head blight resistance at different growth stages leads to inconsistent resistance and unsatisfactory overall resistance. Therefore, the breeding of wheat varieties resistant to Fusarium head blight needs to consider the resistance at different growth stages. This involves cultivating Fusarium head blight-resistant wheat plants at different growth stages to obtain seeds of wheat plants and varieties that exhibit good overall resistance to Fusarium head blight at all growth stages. Utility Model Content

[0004] The purpose of this invention is to provide a breeding device for selecting wheat varieties resistant to Fusarium head blight, in order to address the aforementioned shortcomings in the technology.
