甘薯淀粉是我国轻工业的重要原料之一,为了满足工农业生产对高淀粉甘薯品种的要求,江苏省农科院粮食所在1981～1988年以高淀粉、高产、抗病为主攻目标,从南丰×栗子香的杂交后代中选育出高淀粉新品种苏薯2号(原系号为宁403-180,简称宁180)。1986～1988年江苏省及全国大区区域试验和生产试验的结果表明,苏薯2号鲜产与徐薯18相仿,薯干和淀粉产量都比徐薯18增产10％以上,薯干率和鲜薯淀粉率都比徐
Sweet potato starch is one of the important raw materials for light industry in our country. In order to meet the requirements of industrial and agricultural production for the varieties of high starch sweet potato, the grain of Jiangsu Academy of Agricultural Sciences from 1981 to 1988 with high starch, high yield, disease resistance as the main target, × chestnut fragrant hybrid progeny bred new varieties of high starch new varieties Shu Su 2 (formerly known as Ning 403-180, abbreviated Ning 180). From 1986 to 1988, the results of regional trials and production tests in Jiangsu Province and the whole country showed that the fresh produce of ShuShu No.2 was similar to that of Xushu 18, the yield of dried roots and starch was over 10% higher than that of Xushu 18, Fresh potato starch than Xu
