摘　　要：‘中山6号’是由高RA苷含量品种‘中山4号’(♀)和高总苷含量品种‘中山3号’(♂)杂交优选单株扦插繁殖获得的高总苷、高RA苷含量优良新品种。‘中山6号’的株高平均92.7cm,叶绿色,柳叶形,叶缘锯齿宽且深裂;自然分枝能力良好。该品种始蕾期8月初,干叶收割期在植株始蕾期前一周。干叶原料生产种植平均栽培密度约9000株/667m2,干叶平均产量为220kg/667m2,植株有效成分糖苷总含量(2015检测结果)为21.81%,RA苷含量为13.99%。＂Zhongshan 6＂ is a new Stevia rebaudiana cuhivar, derived from the crossbreeding between female parent ＂Zhongshan 4＂ and male parent ＂Zhongshan 3＂ with characteristics of high total steviol glycosides and Rebaudioside A contents. Both parents are bred by the Institute of Botany. The leaves of ＂Zhongshan 6＂ are willow shaped and green with serrate broad and deep fissure margin. The average plant height of the cuhivar is 92.7 cm. ＂Zhongshan 6＂ has a strong ability to branch. Its bud stage is early August, and the harvest time is 7 days earlier than the bud stage. The average dry leaf yield and planting density of ＂Zhongshan 6＂ are about 220 kilogram and 9000 plants per mu （667m^2）, respectively. The result of 2015 effective ingredient detection showed that the total steviol glycosides content of ＂Zhongshan 6＂ was 21.81% of dry leaf weight, and the content of Rebaudioside A was 13.99%.
