Abstract:

To explore and utilize the precious red rice germplasm resources in China, nutritional value and processing application of red rice were discussed, and relevant situation of 3 independent innovative germplasm (varieties) of red rice was introduced in combination with the germplasm innovation work of our team for many years, and the research direction of red rice was put forward. The results show that red rice contains the same basic nutrients as milled rice, and the types and contents of bioactive substances are higher than milled rice, which can be widely used in food and health products. After many years of independent innovation, our team selected and bred three lines of red rice sterile line ‘Gangte A’, with brown rice rate of 77.6%, head yield of 67.4%, chalkiness of 27.6%, amylose content of 12.4%. Yield of the three-line hybrid rice ‘Gangteyou 8024’ was 9581.6 kg/hm², with brown rice rate of 78.7%, head yield of 60.3%, chalkiness of 7.8%, amylose content of 15.1%. Yield of the two-line hybrid rice ‘E liangyou 32’ was 7307.6 kg/hm², with brown rice rate of 78.9%, head yield of 62.8%, chalkiness of 6.3%, amylose content of 13.3%. In view of the prominent problems of low sales volume and few kinds of red rice and its products in the Chinese market, four research directions of red rice were put forward, including strengthening the research and utilization of existing red rice germplasm resources, breeding new varieties of red rice with high yield and disease resistance, carrying out research on supporting cultivation technology and carrying out research on processing technology. Red rice is a kind of special rice resources with red seed coat due to pigmentation, which has both therapeutic and medicinal value, and has huge market potential. This paper can provide reference for the promotion and application of red rice in production.
