摘要： 为了更好地促进云南甘薯生产，收集云南地方主栽甘薯品种27个进行田间评价，并对其中的6个品种脱毒后进行田间对比试验。试验表明，有些品种产量较高，如‘普洱黄山芋’，产量达20.04 t/hm2，‘丘北白皮’亦达15.60 t/hm2；有些品种品质较好，如‘研和板栗薯’和‘华坪紫心’等；‘研和板栗薯’、‘建水灰薯’、‘华坪紫心’、‘马龙紫薯’、‘昆明紫薯’和‘建水紫薯’6个品种，脱毒后薯块平均增产幅度为175.8%；其中‘建水灰薯’脱毒后产量达24.00 t/hm2，比对照增产16.0 t/hm2，增幅为200.1%。通过脱毒，可以显著提高目前云南主栽甘薯品种的产量，更好为甘薯生产服务。

Abstract: For the purpose of making better use of sweet potato native cultivars in Yunnan, we collected and evaluated 27 native sweet potato cultivars in Yunnan Province, and the 6 native sweet potatoes were had virus-free. The results showed some of native cultivar were of high yield, such as‘Puer Huangshu’(20.04 t/hm2),‘Qiubei Beipi’(15.60 t/hm2), some were of high quality, such as‘Yanhe Banlishu’and‘Huapin Zixin’. After removing virus by shoot apex culture, the yields of six native sweet potato were had virus-free,‘Yanhe Banlishu’,‘Jianshui Huishu’,‘Huaping Zixin’,‘Malong Zishu’,‘Kunming Zishu’,‘Jianshui Zishu’increased by 175.8%-200.1%, the yield of‘Jianshui Huishu’was 24.00 t/hm2, increased by 200.1%. It is recommended to collect the native sweet potato and remove the virus by shoot apex culture. It will provide useful sweet potato cultivar for production.
