Embodiment 1

[0036] (1) Breeding of three-line male sterile lines for beer

[0037] 1) Parent selection: select the three-line indica rice maintainer Hua 2B, denoted by B, and its corresponding sterile line Hua 2A, denoted by A, Jiaxing No. 8, a line with high rice yield and short round grain, is P1, and its gelatinization temperature The line IR24 with low amylose content is P2, the line Guichao 2 with high amylose content is P3, and the line Luhui 37 with high yield and loose arrangement of rice starch is P4;

[0038] 2) Plant P1, P2, P3, P4, and cross P1 / P2, P3 / P4 at flowering stage to get the first generation hybrid F 1-12 , F 1-34 , planting the first generation hybrid F 1-12 , F 1-34 , for hybrid F at flowering stage 1-12 / F 1-34 , have to recross one generation, with F 1-1234 express;

[0039] 3) Plant F 1-1234 , the young ears were taken during the flowering stage, sterilized with 73wt% alcohol, and treated at 8.2°C for 4 days; 2 Disinfect the solution for 10 minutes, wash...

Abstract

The invention discloses a breeding method for hybrid rice special for beer, and belongs to the technical field of special rice breeding. The method uses nonglutinous rice three-line maintainer lines,sterile lines, short and rounded-grain varieties high in head rice rate, varieties low in gelatinization temperature, varieties high in amylose content, varieties high in yield and loose in rice starch arrangement and varieties high in yield, strong in restoring force, high in combining ability and resistant to rice blast as crossing parents; through scientific crossing, matching and offspring screening, the nonglutinous rice three-line maintainer lines and restorer lines which are high in yield, high in head rice rate, short, in rounded-grain shape, low in gelatinization temperature, loose instarch arrangement and high in amylose content are bred respectively; through a matching set of the sterile lines and the restorer lines, first-generation hybrids are subjected to yield comparison, ahigh-yield and good-quality hybrid rice combination suitable for beer brewing is selected out, rice can be used for beer brewing, and economic incomes per mu of farmers can be increased by 550 yuan or more.

Description

technical field [0001] The invention specifically relates to a method for breeding hybrid rice special for beer, and belongs to the technical field of special rice breeding. Background technique [0002] my country's beer industry has developed rapidly and has become the world's largest beer production and sales country. Barley malt is the main raw material for brewing beer. my country's beer production raw material barley is heavily dependent on imports. The production cost of production enterprises is high, the market competitiveness is weak, and the economic benefits are low. Therefore, it is a good choice to develop a high-quality rice raw material that can replace barley malt, with rice as the main ingredient and barley malt as an auxiliary material. The application of rice in beer brewing has great advantages. Rice resources are abundant, there are various varieties, the supply is sufficient, and the price is lower than that of barley malt. In the severe situation of...
