Problems solved by technology

However, the production and processing of formula rice requires special equipment and technological processes, which increases the cost of rice
Moreover, due to the difference in grain shape and water content of different varieties, it is easy to cause more broken rice during mixing processing, which affects economic benefits.

Embodiment Construction

[0015] A method for directly producing japonica glutinous formula rice using special rice varieties, including the following steps:

[0016] 1. New combination breeding of japonica glutinous hybrid rice:

[0017] (1) Transfer of glutinous rice sterile lines: Through the analysis of combination testing and coordination determination, the average cohesiveness of glutinous rice varieties Chengnuo No. 2 is high, and it has a good maintenance effect on the BT sterile line of japonica rice, so the BT japonica infertile line Yang spoke Japonica No. 7 A is the mother, the line Cheng glutinous No. 2 is maintained as the father, and through hybridization and continuous backcroaching, it is transferred to the infertile line of glutinous rice Chengnuo No. 2 A.

[0018] (2) Screening or breeding of excellent recovery lines: BT-type japonica rice restoration line N138 as the mother, the new strain of excellent japonica rice 109-8-1 as the father, through hybridization, backcrossing, directional...

Abstract

The invention discloses a method for directly producing non-glutinous rice formula rice by utilizing a special rice variety. The method comprises the steps of non-glutinous rice hybrid rice new combination breeding, hybrid combination breeding and seed production, formula rice production and the like. According to the invention, the non-glutinous rice hybrid rice variety (combination) is adopted to directly produce the non-glutinous rice formula rice, and the non-glutinous rice formula rice obtained by mechanically mixing non-glutinous rice and glutinous rice of different varieties is replaced, so that special processing equipment and process flow required for producing the non-glutinous rice formula rice are omitted, and the production cost of the formula rice is reduced. And the processed formula rice is soft and glutinous, and is excellent in taste. Meanwhile, due to the fact that the rice sources for producing the formula rice are consistent, the grain shapes and the water content of all grains are the same, the broken rice rate is reduced during processing, and the working efficiency and the economic benefits of formula rice production are remarkably improved. In addition, the japonica-glutinous hybrid rice variety (combination) has the characteristics of high quality, high yield and disease resistance, so that the problem of incoordination of taste, resistance and yield in rice production is effectively solved.

Description

Technical fields: [0001] The present invention relates to a method of directly producing japonica glutinous formula rice using a special rice variety. Background: [0002] Rice is one of the main food crops in China, with the economic development and the improvement of people's living standards, people's requirements for the quality of rice are constantly high, especially the quality of food taste. However, in rice production, there is a widespread problem of uncoordinated taste and resistance and yield, and there are not many varieties of high-quality food taste, and the yield and resistance are poor. From the perspective of food security, large-scale production usually uses high-yield and disease-resistant varieties, and the rice produced is often of poor taste and quality, and its rice texture is hard and lacks waxiness, which is not in line with the eating habits of most people. In order to meet people's needs for high-quality edible rice, a formula rice has emerged on the m...
