what is FFV?

[Stubbornhillfarm]

My boss just asked me what FFV means. He bought some Roma Tomato seeds and says that the package says FFV. I tried looking it up on line quickly with no luck. I am sure someone here knows! Thanks in advance.

Fusarium and Verticilium resistant

Fusarium comes in a bunch of strains. Look closely at the packet and see if somewhere there is an F with a little 1 suibscripted kind of under and to the right, and an f with a little 2 or 3. Those don't refer to hnybridizing generations at all. They will be referring to the strains of fusarium the variety is resistant to.

Oh, and I'm thinking your boss may have gotten the order and sequence of the letters off by a little. The usual sequence starts with the V.

VFFNT, verticilium, fusarium 1, fusarium 2, nematodes, tobacco mosaic

Thank you so much! I will have him bring in the seed pack so that I can look with my own eyes. Yes he certainly may have confussed the order of the letters. Thanks again for sharing your knowledge!

It is a genetically modified organism (GMO)... the plant's genes have been altered to increase its "resistance."

Eww.

Are you certain of that grow?

Way back in the late 1960's there were tomato varieties labelled vf. I think old Rutgers is a vf, and old peron is a vfnt. There are regular genes for resistance to fusarium. They just have thicker tougher stems. If they get the fusarium they have enough stem that makes it to the season's end.

The codes refer to the diseases that the particular tomato plant has resistance to.

V- verticillum wilt
F- fusariuim milt (ff- races 1 and 2 fff-races 1,2,3)
N-nematodes
T-tobacco mosaic virus
A-alternaria stem canker
ST- stemphylium grey leaf spot
TSWV- tomato spotted wilt virus

The Code VFF means that the plant is resistant to Verticillum Wilt and Fusariuim Wilt Race 1 and 2.

There are some tomatoes that are naturally resistant to disease, not all of them are GM or even hybrid. I am growing an heirloom Roma that is resistant to both V/F.

Eww.

Please do some research.. The codes has nothing to do with Genetically Modified Organism's.

In 1934 at Rutgers University there was a cross of the Campbell soup tomato "J.T.D." and the old Marglobe tomato this cross was later named Rutgers and this Rutgers variety was Fusarium Resistant and was coded with a "F". Later after some improvement at Rutgers University the Rutgers tomato was resistant to Verticillium Wilt and Fusarium Wilt and then coded VF as in the Rutgers VF.
The Rutgers tomato is a very popular non-GMO Heirloom Tomato that is correctly labeled Rutgers VF.

Chris, what are some good sites to get that kind of information on?
