2003年通过对云南高原特有魔芋种质资源的地上植株性状和地下植株性状、生产力及其叶片叶绿素含量、叶片光合速率进行了分析研究。结果表明：花魔芋组产量最高是永平花魔芋，为94452kg/hm2、白魔芋组产量最高是魔白14，为57782.4 kg/hm2，野生魔芋组的产量变化极大。下一步经过全省的多点试验后，花魔芋、白魔芋优良种质可在云南魔芋生产上推广应用。

This paper deals with the properties of particular Konjaku grown in the Yunnan plateau. The analyses were taken including underground and on the ground parts in 2003. Moreover, its productivity, the contents of chlorophyll and the speed of photosynthesis were also analyzed. The result showed that the output of Yongping corlored konjaku was the highest yield for 94452kg/hm2 in similar group. The output of white konjaku-14 was the highest yield for 57782.4 kg/hm2 in white group. While the outputs varied greatly in the wild konjaku group. Quality varieties of colored and white konjaku could be extension and applied on the konjaku production area in Yunnan province after numerous trials in different area through the whole province.
