杨瑞芳1,朴钟泽1,万常照1,李钢夑2,龚长春1,白建江1* . 高抗性淀粉水稻新品种优糖稻2号的选育及其特征特性[J]. 中国稻米, 2020 , 26(1) : 94 -95 . DOI: 10.3969/j.issn.1006-8082.2020.01.022
Youtangdao 2 is a new functional japonica rice variety with high resistant starch, which was bred by Crop Breeding and Cultivation Research Institute, Shanghai Academy of Agricultural Sciences by pedigree method. Youtangdao 2 was registered and released by Shanghai Crop Variety Approval Committee in 2019. The content of resistant starch of Youtangdao 2 is as high as 13.1%. Resistant starch is defined as the sum of starch and products of starch degradation not absorbed in the small intestine of healthy individuals. It has the ability to control blood glucose, prevent intestinal diseases, control body weight, promote vitamin and mineral absorption and other important physiological functions. This paper introduced its breeding procedure, seed production, main characteristics, and cultivation techniques points.
