摘　　要：为了选育出适合广西栽培的高淀粉含量能源型甘薯新品种,对9个引进的品种进行对比试验,通过采用随机区组设计,以‘广薯87’为对照,研究不同品种的植株地上部性状、块根性状、鲜薯产量和淀粉含量等。结果表明,JSP-4和‘徐薯22’的淀粉产量较高,分别达到6698.42kg/hm2和5685.96kg/hm2,分别比对照高43.54%和21.84%。通过研究得出,JSP-4和‘徐薯22’可作为高淀粉含量的能源型甘薯品种在广西推广种植。Nine sweet potato varieties with high starch content were introduced and compared,with the aim of selecting new sweet potato varieties suitable for growing in Guangxi.By randomized block design,the plant character,the tuber-root character,the fresh tuber-root yield and the starch content in tuber-root of nine varieties were evaluated.The results showed that,JSP-4 and ’ Xushu 22 ’ had the higher starch yield,which were 6698.42 kg/hm 2 and 5685.96 kg/hm 2,respectively,increasing by 43.54% and 21.84% compared with control.The both would be popularized as bio-energy type sweet potato varieties with high starch content in Guangxi.
