低谷蛋白水稻N198的选育与高产栽培技术 Breeding and High-Yielding Cultivation Techniques of Rice N198 with Low Glutelin Content

N198是广东省农业科学院水稻研究所利用优质籼稻品种五山丝苗为母本，低谷蛋白粳稻品种W3660为父本杂交，经多代回交结合分子标记辅助选择选育出的一个低谷蛋白籼稻新品种。其丰产、稳产性好，米质优，抗稻瘟病，谷蛋白含量低于4%，可作为糖尿病肾病患者的主食或食疗辅助食品。本文简要介绍了N198的选育过程、特征特性以及高产栽培技术。 N198 is an new indica rice with low glutelin content which bred from the cross of Wushansimiao × W3660 by backcross breeding and marker-assisted selection by Rice Research Institute, Guangdong Academy of Agricultural Sciences. It has the characteristics of good and stable yielding, good quality, resistant to rice blast and more importantly with the glutelin content lower than 4%. So N198 is an ideal stable or therapeutic supplementary food for diabetic nephropathy patients. In this paper, we introduced the breeding process, characteristics and high yield cultivation techniques of N198.
