greenhouse tomatoes

[J Peazy]

Do varieties suggested for greenhouses (such as Cobra) do well when planted outside?

If not, why?

Some do, some don't.

A good example is Campari which was bred for the controlled conditions of greenhouse growing, which doesn't do well outside which is why several folks have gone to Mt Magic F1, bred by Dr. Randy Gardner, also a Campari type, which does wonderfully outside.

The difference is breeding tomatoes for hydroponics, mainly, that are bred for inside controlled conditions as opposed to outside uncontrolled conditions, as I see it.

Thanks Carolyn,
By reversing that thought, I wonder what tomato is best for highly variable out side conditions? One that can stand all kinds of extremes. My first though is stupice. Now that the new dwarfs are out, which one/ones of them?

OK, lets go back a bit. Controlled conditions in a greenhouse, usually done with hydroponic bred varieties, allows for constant feed, constant temp, no systemic or foliage diseases etc.

Outside conditions are variable every season, in different geographic areas in the same season and nothing is controlled.

And I think that applies to all varieties grown outside as to variable conditions. So I wouldn't select Stupice or its lookalike Matina, which I prefer, to be any better than many other varieties in that regard.

IMO it's just constant trialing of varieties that will hopefully allow a person to build up a list of those that do well in most seasons and most conditions, as well as allowing for good taste to develop as well.

Makes sense?

How about growing under lights, in any season? Do people do that? Have you any info on timeing of lights?

[Skaggydog]

Oh sorry. If I'm hijacking this thread I can delete and start elsewere.

For obvious reasons, the types of tomatoes recommended for both glasshouse/hoophouse and field culture are modern hybrids with multiple disease resistance. Here are a few I believe will work for you:

Mochomo Hybrid: Roma type, 6 oz., dark red fruit with dense flesh, strong foliage canopy for sunburn protection, compact indeterminate vine, tolerant of F, TMV, TSWV, TYLC, V.

Pamela Hybrid: 7+ ounce globe, red fruit, indeterminate with vigorous leaf canopy to prevent sunburn, tolerant of F, N, TMV, TSWV, TYLC, V.

IT-01-27 Hybrid: Early, 7 ounce cluster tomato with bright red fruit on vigorous indeterminate vine, long shelf life gene, tolerant of F, TMV TSWV, TYLC, V.

PS 01522935 Hybrid: Early midseason, 8 - 12 oz. round, red tomato on vigorous determinate vine, holds up well in hot, dry or wet climates, resistant to ASC, F, N, St, TSW, TSWV, TYLC, V.

The above varieties are available from Twilley Seed (www.twilleyseed.com)

Favorita (F1): 58 days, deep red cherry with improved flavor, 1.25 inch dia., 0.6 ounce, deep red berries in long trusses. F, LM, N, TMV.

Favorita is available from Johnny's Selected Seeds (www.Johnnyseeds.com)

There are others, and I have seen various indeterminate and determinate field tomatoes grown in hoophouses (for example Big Beef and Fabulous), but with variable results with regard to leaf disorders, fruit quality, and BER.

Well yes, but somehow I got the impression he was asking about non-hybrids, especially when he mentioned Stupice.

And I'm fondling the pack of Jet Star F1's I recently bought and am also looking to see if I have a few seeds of MM F1 for freda to sow seeds for b/c if this upcoming season is as bad as the previous two, well, I guess there's nothing I can do about controlling the weather.

Yes, I re-read his post again and see I made the error of thinking he was looking for varieties he could grow both inside and outside the greenhouse. My mistake. But yes, I think Mountain Magic is a variety that could be grown in a greenhouse with very little problems. It did very well outside under lots of pressure.

Carolyn, that is why I sent you the two selections from Randy Gardner. They have the genes for resistance to early blight and late blight, plus they are selected for significantly better than average flavor.

Darrel, his Early Blight gene isn't that good although it's the best out there, unless I'm missing some new A solani tolerance gene and several years ago he told me that basically it meant the difference between a commercial farmer spraying every 4-5 days to going out to maybe 7-8 days, which is a huge savings for the commercial farmer.

And yes, I know he has probably the up to date latest genes for Late blight as well.

I thought some of the other ones Randy sent me a couple of years ago were darn good and I hope to find room for the two you sent me. I owe Randy an e-mail so will find out what the parentage is b'c last time he gave me the complete parentage and genes bred in.

Thanks heavens that Late BLight is only an occasional problem where I now live, except for 2008 when the NE was hit so bad, but my plants here at home never became infected.
