| 英文摘要: |
| Phytophthora heart rot is one of the most serious diseases in pineapple, is a kind of soil borne disease
caused by Phytophthora nicotianae and hard to control. To obtain some materials resistant to P. nicotianae in the pineapple
production and breeding, the resistance of 117 pineapple materials to P. nicotianae was identified by in vitro leaf method.
The results showed that the resistance to P. nicotianae of different pineapple materials varied widely. There were 38 kinds
of highly resistant, 24 kinds of resistant resource, 17 kinds of middle resistant and 38 kinds of susceptible resource, which
occupied 32.48%, 20.51%, 14.53% and 32.48%, respectively. All these results showed that there were plenty of antidisease
sources in recent pineapple resources, and they could be applied in pineapple breeding for resistance to
phytophthora heart rot. |
