Example Embodiment

[0026] Example 1: In this example, 12 production promotion rice varieties (combinations) collected independently and their parent materials were measured in 2020. The rice varieties include Jia 58, Jiayou Zhongke No. 3, and Jiayou Zhongke No. 2 , Jiayou Zhongke 13-1, Xiushui 134, Zhongke Jiahui No. 1, Zhongke No. 2, Zhongke Jiahui 1293, Jia 87, Jia 67, Jiahui 193, Jiahui 448. Indica rice and japonica rice varieties (materials) aiming at screening the evaluation criteria were used as donor parents for high-quality rice breeding. Control varieties: Jia 58, Jia Hui 193.

[0027] Application of an alkaline consumption value test method, a rice quality measurement method and an alkaline consumption value test method as the identification of the alkali consumption value of a single plant in the breeding of rice mass breeding materials, and the rice quality determination method as a single plant breeding in rice mass breeding The application of rice quality identification includes t...

Example Embodiment

[0053] Implementation case two:

Example Embodiment

[0054] Example 2 Using the present invention to select and breed a high-quality restorer line Jiahui 891, Jiahui 891 is a high-quality restorer line, and the self-selected Jiahui 193 and Jiahui 448 were crossed, and the two places were promoted by more than one generation for one year. In the autumn of 2017 stereotypes. Specifically, from 2017, through the identification and screening of the F5 generation intermediate line after self-crossing with Jiahui 193 and Jiahui 448 as the parents, after multi-generation selection and breeding. The selection included 20 lines that reached the breeding target standards in terms of yield, resistance, and appearance quality. One individual plant was selected for each line, numbered WF51-1 to WF51-20. In this example, the alkali elimination value of 20 individual plants was identified by the improved alkali elimination value determination method, in order to further screen the materials with high alkali elimination value.

Abstract

The invention belongs to the technical field of agricultural production, and particularly provides an alkali spreading value test method, a rice quality determination method and application thereof. The alkali spreading value test method is characterized in that: a sample adopts brown rice with two ends cut off; as the grading of alkali spreading values is determined according to the observed decomposition condition of the rice grain, if the decomposition degree is that the rice grains are not dissolved, determining alkali spreading values to be 1-5 grades; and if the decomposition degree is that the rice grain is partially dispersed and dissolved or completely dispersed and dissolved, determining the alkali spreading values to be 6-7. Compared with the prior art, the alkali spreading value test method is fast, efficient and cost-saving.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, in particular to the improvement of the traditional alkali digestion method, and relates to an improved alkali digestion method, its application and its identification method for rice breeding. Background technique [0002] Rice is one of the most important food crops in the world. With the increasing living standards of urban and rural residents, people's consumption demand for rice is also changing, and the quality requirements for high-quality edible varieties are getting higher and higher. On the basis of high yield, high-quality rice is a new direction for rice breeding. Rice quality is divided into six categories: rice milling quality, appearance quality, nutritional quality, cooking quality, eating quality and hygienic quality. Because some of the above quality indicators are relatively subjective, people have studied many objective physical and chemical qualities related t...
