M1 gene

[J Peazy]

I have been reading a little about the M1 gene that confers nematode resistance in tomatoes.

From what I read this gene may also make tomatoes resistant to aphids.

Does anyone have any experience with this? Supposedly Patio F1 has the gene but I have had aphid problems with those.

I understand the gene in L. Esculentum comes from hybridization with L. Peruvianum. Is this correct? If so, which varieties have the gene?

I do notice that some of my tomato varieties are hit by aphids while others close by are left unscathed.

For example, I currently have a Jet Star F1 that is being eaten alive by aphids. Two feet away I have an F3 cherry-type that I planted from a store-bought tomato. I posted pictures to this forum and a member was kind enough to tell me that he thought my tomato had "wild" characteristics based on what he saw. http://www.tomatoville.com/showthread.php?t=18488

Any insight would be appreciated.

The only significant aphid tolerance is in a different wild species and is linked to trichome structure. There is some breeding work ongoing to incorporate this into a domestic tomato. Google
