| 摘 要： | 在对85份烟草种质及46份烤烟F1组合进行的青枯病抗性鉴定中,未发现免疫或高抗材料,但不同材料对青枯病的抗性表现不同,感病材料发病早,病情指数上升速度快;抗病材料发病迟,病情指数上升速度慢.85份种质中筛选出了OX2028、RG17、K358等10份抗病种质及岩烟97、RG11、OX940等24份中抗青枯病种质.杂交组合的抗病性总体上优于烟草种质,以抗或中抗为主,但没有明显优势,其抗性多偏向于抗病性弱的亲本.

| Abstract: | The resistance to bacterial wilt of 85 tobacco germ resources and 46 hybridized combinations of flue-cured tobacco were evaluated .The results showed that there were no immune or high-resistance cultivars. The symptom found in sensitive cultivars was earlier than resistive cultivars . the upswing speed of disease index in sensitive cultivars was rapider than resistive cultivars. 10 resistive cultivars , such as OX2028?RG17?K358, and 24 mid-resistive cultivars such as Yangyan 97?RG11?OX940 , were identified in 85 cultivars.As a whole the resistance of F 1 beng resistive or mid-resistive were higher than tobacco germ, but no sighificant aduantage. Their resistance tended to low-resistiveparent. |
