| 中文摘要: |
| 在玉米粗缩病大发生年，观察品种、自交系及育种材料的发病率表明，品种间抗病性差异显著。对185份自交系抗病鉴定表明不同种质材料的选系抗病性差异悬殊。对6个亲本自交系双列杂交的9个杂交种抗病性分析结果，亲本对后代有一定遗传力，各亲本自交系的一般配合力效应差异显著。 |
| 英文摘要: |
| An observation on vareities and breeding materials was carried on the epidemic year ofMRDV. The results showed that the disease-resistance differs greatly among varieties and inbred linesused.Analysis on double row cross of six inbred lines parents showed that the disease-resistance is heredi-tary.All the parents differ obviously in general combining ability.It’s important in selecting disease-re-sistant inbred line and varieties. |
