Have you observed or are there any known cultivars that exhibit resistance to "bunchy top."

Thank you in advance.

All bananas (cultivars, species) are suspectible to the banana bunchy top virus.

But, in Hawaii the Cavendish types are more susceptible; they develop severe symptoms quite rapidly and fields can be lost.

The Dwarf Brazilian 'Santa Catarina' bananas are less susceptible in the sense that they develop symptoms more slowly than Cavendish.

Most of our Cavendish ('Williams') farmers in Hawaii had to make a switch from Cavendish to Dwarf Brazilian in order to stay in business farming bananas, and it worked for them in areas under high bunchy top pressure.

We think that Dwarf Brazilian bananas are physically tougher, that is, they are more difficult to knock down with bulldozers than are the 'Williams.' This toughness (more Si in their tissues?) in the plant tissues might interfere with banana aphid feeding behavior.

Interstingly, Australia and Hawaii scientists are indepdently working to produce GMO bananas; early reports indicate that they have produced some BBTV-resistant plants. I do not think the plants are available for the general public (at least not in Hawaii) at this time. I think some more work is required.

I hope this answers your question.

I am also Scot N. It is weird to see these posts knowing that it is not me. Believe it or not, there is one other Scot Nyman that I have ever heard about. We are not related, but of all the places in the world to find him, he lived about 3 miles away from my old house. (of course he spelled Scot incorrectly - Scott)
Once I got a call from a bill collector asking me to pay up on a hospital bill for drug rehab. After checking SS#'s they apologized.
Sheesh!

Yes Dr. Nelson, Thank you. Is it a private or govermental research work into Genetically modified organisms in Australia, specifically bananas?

Also have the Fe'i there in Hawaii been included in "observations"?

So Mr. Nelson, do you think that feeding silica to banana plants will be advantageous to their stem walls to prevent bugs and wind damage?
