Problems solved by technology

However, some white-grained wheat varieties with excellent disease resistance, comprehensive agronomic traits and processing quality, such as the famous Zhongyou 9507, cannot be popularized on a large scale just because of serious ear germination hazards in production.

Embodiment 1

[0017] Embodiment 1, auxiliary identification white-grained wheat varieties resistant to panicle germination

[0018] Among the white-grained wheat varieties Zhongyou 9507, Dongfeng No. 1, Jing 411, Zhongmai No. 9, Zhongmai 12, Zhonghan 110, Beijing 0045, Hengguan 35 and Shijiazhuang No. 8, etc., which have passed the examination and approval, screened Varieties with the following morphological characteristics: there is wax powder on the glume, no gaps at the junction of the glumes can be seen with the naked eye during the wax ripening stage of wheat, and the grains are not adhered to the inner wall of the glumes. The results showed that in Zhongyou 9507 husk pine, the gap between the inner and outer glumes could be seen with the naked eye at the wax ripening stage of wheat, and ear germination was prone to occur when water accumulated in the husk when it rained. There is wax powder on the glume husk of Zhongmai No. 9, and the gap at the junction of the glume and the glume is ...

Abstract

The invention discloses a method of accessorial appraise for the sample of anti stachys white grain wheat. The method is that select white chondrio wheat as alternate samples. The characteristic is that there are wax powders on the glume, during the wax ripe, naked eye cannot see gap at the link of inside and outside of glume, and there is not synechia between seeds and the inner wall of inside and outside of glume. The method of accessorial appraise for the sample of anti stachys white chondrio wheat bonds the method of normal breed, can quicken the procedure of breed wheat; can select quickly the sample of anti stachys white grain wheat from the heavy product, superior quality and against disease of white grain wheat with other normal measuring method, and plunge it into production quickly.

Description

technical field [0001] The invention relates to a method for assisting identification of white-grained wheat varieties resistant to panicle germination. Background technique [0002] Ear germination is one of the main natural disasters in wheat production, which seriously affects the quality and yield of wheat. Before the 1990s, the rainy wheat-producing areas around the world mainly relied on the strong dormancy characteristics of red-skinned wheat to control the hazards of ear germination in production, but white-skinned wheat was more popular in the market. Therefore, the selection and breeding of white-skinned wheat varieties resistant to panicle germination have been proposed in the world since the 1980s, and some progress has been made. [0003] The patent applicant Xiao Shihe and others have been working in this field for more than 20 years, and have bred a batch of white-skinned wheat varieties resistant to panicle germination, some of which have been widely promote...
