| 摘 要： | 甘薯抗旱性鉴定结果表明，栽后连续干旱７０天，徐薯１８（ｃｋ）的植株存活率为３０．０％，豫薯１３号、遗３０６、豫薯１０号、豫薯１１号和辽薯４４存活率高于４０％，表明这些品种（系）抗旱性较强；甘薯品种地上部生长与其抗旱性偏相关不显著。因此，不能以植株地上部生长作为甘薯品种抗旱性强弱的评价根据

| Abstract: | The identification of drought resistance of sweet potato varieties showed that,after consecutive 70 days of drought,the survival rate of Xushu 18 was 30.0%,and that of Yushu 13,Yi 306,Yushu 10,Yushu 11 and Liaoshu 44 was over 40%,indicating these varieties have stronger drought resistance.The partial correlation between the growth of the part above the ground of sweet potato and the drought resistance was not significant ,thus the growth of the part above the ground couldn't be used as a standard for the identification of the drought resistance of sweet potato. |
