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20.04t/hm2,‘丘北白皮’亦达15.60t/hm22;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24.00t/hm2,比对照增产16.0t/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。
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/hm 2）,＇ Qiubei Beipi ＇（15.60 t/hm 2）,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/hm 2,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.
