Abstract

The invention discloses a breeding method of a special japonica rice restorer for beer, and belongs to the technical field of special rice breeding. According to the method, a japonica rice strain which is high in head rice rate, short, round and high in yield, a japonica rice strain low in gelatinization temperature, an indica rice strain with which is high in restoring capacity, good in matchingperformance, loose in rice starch distribution and high in amylase content, and a high-yield, disease-resistant and cold-resistant japonica rice strain serve as parents, and through scientific hybridization matching and target trait screening, the high-yield, cold-resistant, disease-resistant, short rounded grain special beer japonica rice restorer with the high head rice rate, the low gelatinization temperature, the loose starch distribution, the high rice amylase content and the good matching performance is bred. The restorer or hybrid rice matched with the restorer can be used for beer brewing, and the economic income can be increased by 500 yuan or above per mu for farmers in the planting process. The method is scientific, efficient and easy to operate, and plays a certain role in breeding of special rice varieties.

Description

technical field [0001] The invention specifically relates to a method for selecting a restorer line of japonica rice specially used for beer, and belongs to the technical field of special rice breeding. Background technique [0002] Beer is a nutritious food recognized by the world, and it is also a perennial international beverage, known as "liquid bread". In the past two decades, my country's beer industry has developed rapidly. Beer production accounts for nearly two-thirds of the country's total alcoholic beverages, and it is on the rise year by year. The output ranks first in the world, and it has become the world's largest beer production and sales country. For a long time, barley malt has become the main raw material for brewing beer due to its superior characteristics. Many beer manufacturers use imported barley, and there are many unstable factors. Due to the heavy dependence on imports of raw materials, especially the increase in the price of malt, the production ...
