贵州马铃薯主要品系淀粉含量测定

目的]鉴定出贵州省主要马铃薯品系中的淀粉加工型原料品种,以加快淀粉加工优良品种的选育。方法]采用DNS比色法对贵州省马铃薯研究所提供的甘农薯3号、超米拉、S01-295、B01-41-4、费乌瑞它、合作88、B01-21-1、黔彩薯1号、威芋3号、W26-27、新大坪、威芋1号、会-2共13个马铃薯品系进行淀粉含量的测定。结果]试验表明,贵州省13个马铃薯品系中有5个品系的淀粉含量超过18.0%,分别为甘农薯3号20.2%,S01-295 18.1%,合作88 18.7%,威芋3号18.9%,威芋1号20.1%,最高淀粉含量为甘农薯3号20.2%。结论]试验得出的淀粉含量较高的几个马铃薯品系,可作为淀粉加工专用品种。

Determination of the Starch Content in Potato from Guizhou Province

Objective] The potato variety suitable for the raw material of starchprocessing in Guizhou Province was identified to speed up elite variety breeding.Method] The content of potato starch in 13 varieties-Gannongshu No.3,Chaomila,S01-295,B01-41-4,Favorita,Hezuo 88,B01-21-1,Qiancaishu No.1,Weiyu No.3,W26-27,Xindaping,Weiyu No.1 and Hui-2,provided by the Potato Research Institute of Guizhou Province,was tested with DNS method.Results] The testing result showed that the content of starch of 5 varieties was more than 18.0%, which were Gannongshu No.3(20.2%),S01-295(18.1%),Hezuo 88(18.7%),Weiyu No.3(18.9%) and Weiyu No.1(20.1%),respectively.The variety with the highest content(20.2%) of starch was the Gannongshu No.3.Conclusion] Several potato varieties with high starch content were selected,which could be used as a special variety of starch-processing.
