100% blight resistant tomato

Via The Royal Horticultural Society in the UK: how about this? 100% blight resistant tomato, looks like it's only available as plants in UK at this time.

That's very interesting. I tried to buy some but I couldn't get past the "Country" drop down box on the Sutton registration page. They cost 7.99 pounds plus another 4.99 pounds shipping. That's some serious funds.

Lot of hype, but the tomato just has ph2 and ph3. It is also selected for good flavor. As any good tomato breeder would tell you, there are NO totally blight resistant tomatoes.

You can find info about ph2 and ph3 in the breeding work Randy Gardner did on the Mountain series. Also, Amelia is a commonly available variety with both ph2 and ph3.

I'm not exactly pooh poohing the tomato, I'd love to trial it, but that price is way too high and the hype smells like a used car salesman.

I agree with your statements about the hype and pricing and Randy Gardner and the Mountain series but when I looked up Amelia I could find no reference to ph2 or ph3, perhaps I am looking in the wrong places?

The difference between this and the Mountain series is that it may be OP and therefore homozygous for both genes compared to the heterozygous expression in Mountain Magic F1, for example. I don't know of any previously released lines that are homozygous for both.

I am feeling that I may have to trial some in 2015. Dar, I owe you some seeds so I will save you some from this.

Iron Lady, I think. An F1 though.

Agree with Dar. And, if this was the description of the tomato from one of the big seed companies everybody loves to hate here, I suspect the comments wouldn't be as charitable.

I down loaded the Tomato Chooser app, and found that Early Blight and Late Blight is common for my area(Tulsa OK). Looking at the pictures provided, it was EB. The app suggested 6 tomatoes with resistance to both EB and LB. 3 of them are Eva's Purple Ball, Difiant, and Mountain Magic.

I know this is an old thread... I was surfing about, as you do and I read Suttons are intending to supply seed of crimson crush after September, so it'll hopefully be a bit less extortionately priced.

Strangely on our main gardening tele programme the presenter, Monty Don, is trialling 4 blight resistant varieties but not Crimson Crush which is weird as these are usually promotional showcases. I think he's trying Lizzano, losetto, Fandango and another one called experimental something or other

Depending on how things go with this years crop I may be tempted by one or all of them

although Fandango would be most likely as I like medium sized toms and I love the name

Agree with Fusion that there is NO variety totally resistant to blight, and the word blight can mean many things, but when they referred to ph2 and ph3 they are talking Late Blight, aka Phytopthera infestans. Perhaps some varieties are more tolerant to Late Blight under certain conditions, but totally resistant, no.

True, but it does actually say this:

Quote:

it has the PH2 and PH3 genes which make it resistant to all common British blight strains

elsewhere on the Suttons website it also says this:

Quote:

The varieties Tomato Lizzano and Tomato Crimson Crush show some resistance to tomato blight. This variety is resistant but not immune and may still be attacked by blight.

So I would suggest they can be forgiven for being a bit over excited. Heck, I am! What's not to be excited about? A decent sized OP blight resistant tomato that tastes good! WOO HOO!

PhilaGardener · December 18, 2014

Certainly sounds like it is worth trialing widely! Being homozygous for Ph2 and Ph3, Crimson Crush should be able to be maintained by selfing, which is not true for Mountain Magic (F1 and heterozygous at these loci).

Because only plants are available this year, we will have to rely on our friends across the pond to save seed.

Resistant does not mean immune.

I agree but perhaps it's a British term, and if it is I still don't equate tomato resistance with tomato immunity b/c immunity does not apply to tomatoes.

Correcting one item above, it is Mountain Merit and Iron Lady that have ph2 and ph3, not Amelia which has SW5 and F1, 2, 3. I've read more about this tomato over the last few hours and find the media sensationalism to be way over the top.

I have several lines from Randy Gardner that are now homozygous for ph2 and ph3. One of them is from a cross with Brandywine. I should re-grow that line this year and see if there is something worth carrying further.

Mulch is what prevents blight. The spores are in dirt, which splashes up on the lower part of the plant in a hard rain if you don't have mulch. The problem is so easy to fix with mulch -at least in my experience and location - that it seems a waste of breeders' talents to even attempt to address.

I would have to politely disagree. All my tomato beds were mulched. All my beds were devastated by late blight.
