| 中文摘要: |
| 12个深水稻品种对稻纹枯病抗性进行盆栽接种测定和品种农艺性状调查的结果显示,深水稻品种与感病对照在抗性水平上存在极显著的差异。大部分供试深水稻品种的抗性都在抗至中抗之间,个别品种还表现出较高的抗性水平。深水稻品种间抗性存在显著差异,但抗性与品种的生育期以及株型性状等没有显著的相关性。 |
| 英文摘要: |
| Resistance of 12 deep-water rice varieties to rice sheath blight was studied by potted plant test of inoculation in greenhouse. The agronomic characters of these test varieties were investigated at the same time. The results indicated that highly significant difference in sheath blight resistance level were showed among the test deep-water rice varieties and between them and susceptible check. Most of these test varieties were between R( resistant) and MR (middle resistant), while some HR(high resistant). Correlation coefficients between resistance and heading date,and between resistance and plant height (including other agronomic characters), were not significantly large. |
