  • The content of twenty one fresh purple sweet potato in dry matter,starch,soluble sugar,crude protein and anthocyanin were 25.9%-36.8%,17.5%-31.1%,2.98%-5.14%,1.27%-5.26% and 18.1-93.1 mgg-1,respectively.Yields of the sweet potato in fresh and dry root tubers were 1.6-19.5 tm-2 and 0.5-6.6 tm-2,respectively;the yield in nutritive components were 0.4-4.3 tm-2 and 0.6-14.0 kgm-2 for starch and anthocyanin,respectively.Comparing with Guangzishu no.1 as control,results indicated that Zhanshu 03-40 increased significantly in the yield of dry roots and starch,Xu13-4 was remarkable in the yield of starch and anthocyanin,and Guangzishu no.2 also showed significance in the yield of anthocyanin.The germplasm with remarkable nutrition and yield was found more in breeding varieties than in landrace;however,the germplasm better in taste was found mostly from landraces.It suggests that Xu 13-4,Guangzishu no.2,Jingshu no.6,Zhanshu 03-40,Zhanyin 42 and Lingao 17 are good in nutrition and yield for hybridization between breeding varieties and landraces.
