摘　　要：通过对7个脱毒甘薯品种进行比较试验,结果表明:产量高低依次为苏薯8号(5504.2 kg/667m2)、北京553(5098.7 kg/667m2)、豫薯王、徐薯18、遗字138-3、鲁薯8号、甘薯1号(CK);淀粉含量依次为甘薯1号(20.76%)、徐薯18(20.06%)、鲁薯8号、豫薯王、遗字138-3、北京553、苏薯8号(8.25%);根据各品种的淀粉含量特点可将其分成加工型(甘薯1号、徐薯18、鲁薯8号)、兼用型(豫薯王)和鲜食型(遗字138-3、北京553、苏薯8号)3种类型。7 sweet potato varieties with virus-free were tested to investigate their yield and quality. The results show that the yield and starch content of Sushu 8, Beijing 553, Yushuwang, Xushu 18, Yizi 138-3, Lushu 8 and Ganshu I（CK） were 5504.2 kg/667m^2 and 8.25%, 5098.7 kg/667m^2 and 12. 91%, 4287.2 kg/667m^2 and 18. 68%, 4226. 7 kg/667m^2 and 20.06%, 3851.1 kg/667m^2 and 13.11%, 3726.4 kg/667m^2 and 20.00%, 3515.9 kg/667m^2 and 20.76% respectively. These varieties can be divided into the processing type （Ganshu 1, Xushu 18 and Lushu 8）, dual purpose type （Yushuwang） and fresh food type （Yizi 138-3, Beijing 553 and Sushu 8） according to the starch content.
