| 摘 要： | 对4个木薯品种——华南7号、KU50、南美1号、华南205在云南省元谋县、保山市隆阳区和永德县3个点进行区域试验。结果表明，南美1号在隆阳区试验点的鲜薯产量最高(59 548.5 kg/hm2)，KU50在永德县鲜薯产量最低(32 812.5 kg/hm2)；KU50在元谋县的干物质含量最高(47.6%)，在隆阳区试验点最低(27.3%)；华南205在永德县的淀粉含量最高(41.7%)，在隆阳区试验点最低(27.2%)。综合3个主要指标，KU50在元谋县干热区适应性最好，可作为该地区推广种植品种；KU50和南美1号可作为隆阳区的推广种植品种；华南205可在永德县推广种植。

| Abstract: | A regional experiment was carried out in Yuanmou, Baoshan, Yongde for four varieties of Cassava-SC7, KU50, South America No1 and SC205. It showed that South America No1 had high yield in Baoshan. Its yield reached 59 548.5 kg/hm2. The lowest yield was KU50 in Yongde. Its yield was 32 812.5 kg/hm2. The highest dry matter content was KU50 in Yuanmou approached 47.6%. The lowest dry matter content was KU50 in Baoshan, 27.3%. The highest starch content was SC205 in Yongde approached 41.7%. The lowest starch content was SC205 in Baoshan, 27.2%. According to the 3 indexes, yield, dry matter content and starch content, KU50 was adapted in dry-hot region like Yuanmou. It could be popularized in this region. The recommend varieties in Baoshan were KU50, South America No1. In Yongde, SC205 was suitable to plant. |
