Embodiment 1

[0024] A kind of breeding method of beer special rice, concrete steps are:

[0025] 1) Select a japonica rice line P1-Wujing 075 with a high rice milling rate and a short round grain type, a japonica rice line P2-Yanjing 2 with a low gelatinization temperature, and an indica rice line P3-Luhui with a high amylose content and loose rice starch arrangement 6684, a high-yield, cold-resistant and blast-resistant japonica rice line P4-Lijing 314; crossed P1 / P2, P1 / P3 and P1 / P4 to obtain the first generation of hybrid F 1-12 , F 1-13 and F 1-14 ;

[0026] 2) Planting hybrid first generation F 1-12 , F 1-13 and F 1-14 , the flowering period is represented by F 1-12 F 1-13 and F 1-14 cross again to obtain the first generation of recrossing, with F 1-123 and F 1-124 express;

[0027] 3) Plant F 1-123 and F 1-124， F 1-123 / F 1-124 , the harvested seeds must be recrossed for one generation, with F 1-1234 express;

[0028] 4) Plant F 1-1234 , harvest the seeds to get F ...

Embodiment 2

[0038] A kind of breeding method of beer special rice, concrete steps are:

[0039] 1) Select a japonica rice line P1-Wujing 075 with a high rice milling rate and a short round grain type, a japonica rice line P2-Yanjing 2 with a low gelatinization temperature, and an indica rice line P3-Luhui with a high amylose content and loose rice starch arrangement 37. High-yielding, cold-resistant and blast-resistant japonica rice line P4-Lijing 314; crossed P1 / P2, P1 / P3 and P1 / P4 to obtain the first generation of hybrid F 1-12 , F 1-13 and F 1-14 ;

[0040] 2) Planting hybrid first generation F 1-12 , F 1-13 and F 1-14 , the flowering period is represented by F 1-12 F 1-13 and F 1-14 cross again to obtain the first generation of recrossing, with F 1-123 and F 1-124 express;

[0041] 3) Plant F 1-123 and F 1-124， F 1-123 / F 1-124 , the harvested seeds must be recrossed for one generation, with F 1-1234 express;

Abstract

The invention discloses a breeding method of special rice for beer, and belongs to the technical field of breeding of special rice. According to the method, a short rounded grain japonica rice strainwith a high head rice rate, a japonica rice strain with a low gelatinization temperature, an indica rice strain with a high rice amylase content and loose starch distribution, 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, shortrounded grain special beer rice with the high head rice rate, the low gelatinization temperature, the loose starch distribution and the high rice amylase content is bred. The special rice is suitablefor beer brewing, and the economic income can be increased by 550 yuan or above per mu for farmers in the planting process. The method is scientific, efficient and easy to operate, and lays a foundation for breeding of special rice varieties and industrial development of beer rice.

Description

technical field [0001] The invention specifically relates to a method for breeding special rice for beer, and belongs to the technical field of special rice breeding. Background technique [0002] Beer is a world-recognized nutritious food and an everlasting 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 has been increasing 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 costs of many beer production enterprises have ...
