摘要‘滇优1号’属于竹亚科Bambusoideae玉山竹属Yushania Keng f.的湿地玉山竹Yushania uliginosa Yi et J. Y. Shi。因湿地玉山竹具有独特的耐湿、耐寒特性，曾于2004年、2008年先后2次从云南大理白族自治州云龙县海拔2 500 m处，小规模引种到海拔2 000 m的昆明金殿公园种植，其后曾经历数次淹没和浸泡，但依然生长良好。2015年5月，鉴于该竹的特殊价值，又在昆明呈贡滇池国际登录园苗圃继续扩大种植，规模达到4 000多株。经专家实地考察，发现该湿地玉山竹人工居群的各项特征与野生居群基本一致，除适应较低海拔的不同环境外，其竹丛明显矮小、叶片更纤细、节间更短、笋色更偏绿，但总体长势良好，各项特征表现稳定，因此确认为野生竹人工引种培育成功的一个栽培新品种，并定名为‘滇优1号’，学名为Yushania uliginosa ‘Dianyou 1’。
Abstract：‘Dianyou 1’ is a new hydrophytic bamboo cultivar from Yushania uliginosa Yi et J. Y. Shi in the genus of Yushania Keng f. of Bambusoideae. In 2004 and 2008, this new hydrophytic bamboo cultivar was introduced into Jindian Park, Kunming, from a place at 2 500 m altitude in Yunlong County, Dali Bai Autonomous Prefecture. Meanwhile, the bamboo grew well even after inundation and immersion for several times. In May 2015, the bamboo was transplanted into the International Cultivar Registration Garden for Bamboos located in Chenggong District, Kunming, and have been expanded to more than 4 000 individual plants. After the field investigation, it was found that the introduced bamboo plants had almost the same features as the ones of the wild population. Except that the bamboo groves were obviously shorter, with more slender leaves, shorter internodes and greener bamboo shoots by adapting to the lower altitude (2 000 m), the bamboo plants have grown well, showing the stable characteristics. Thus this bamboo cultivar was identified as a new bamboo cultivar with the scientific name of Yushania uliginosa ‘Dianyou 1’.
