| 摘 要： | 选用目前生产上推广面积较大的几个品种，经多年多点鉴定结果表明，脱毒甘薯不同地点、品种、年份均表现增产，增产幅度为１４．９５％～９１．６１％。甘薯脱毒后干物质含量、抗病性则无明显变化。脱毒薯比非脱毒薯地上部生长旺盛，后期干物质积累优势突出。用脱毒苗作有性杂交亲本比对照结实率略高，植株开花性状、实生后代表现无明显差异。 |
| 关 键 词： | 甘薯 脱毒 干物质含量 抗病性 |

| Abstract: | Application of virus-free sweet potato is a breakthrough of sweet potato production. Several popular varieties were adopted to study their yield increase potential and their use in breeding in this re- search. The results showed that after virus elimination, all varieties had a yield increase ranging from 14. 95%- 91. 61% and marketable quality improvement, despite of the changes in location and season. The changes of dry matter content and disease resistance were not significant. Virus-free sweet potato per- formed vigorous vine growth and strong dry matter accumulation ability. Virus-free parents have a slightly higher seed setting percentage, but the flowering ability and the performance of off-springs were similar to that of the check plants. |
