imgur.com/X0KGvClick on the photo for a larger view. MAGIC TRICK is doing well with what looks like total tolerance to late blight. The tomato vine you see at the front of the row is still blooming and has perfect unripened fruit yet on the vine...I just picked the red tomatoes minutes before. This was part of a super late transplanting to test for late blight. Note the dead and blacked vines just beyond Magic Trick. This happens to be the first picture I have been able to post from my cell phone. My son Kael Wagner helped me sync the phone to my PC. MAGIC TRICK will be available on the newworldcrops.com website whenever I find the time to update it. Tom Wagner

nice foliage. I presume you got hit again with race 22.
Have you managed a late blight tolerant variety that is also large fruited? That has been Randy Gardner's bugaboo, high tolerance to LB but fruit size is small.
I have 2 possible candidates in the large fruited category. One is a nearly round pink and the other is from a cross with a black variety. Both are from breeding material Randy supplied.

I have the Skykomish series and the segregating populations from them which are showing good size and blight resistance. My problem is that I have tomato patches scattered all over and some areas are not going to give me picture perfect proof.
With deer getting many of the plots and plants being pulled early, I just don't get the kind of info I need. The knack of getting homozygous lines is difficult since I have way too many projects and not enough of most plants to get replicated plots of favored lines. Far too many of my breeding lines show a fair amount of tolerance but I can't prove the segregation.
I am using Randy's material along with some other sources.

I'm getting hit hard with early blight but late blight is erratic.
I grew about 50 S. Pimpinellifolium lines this year just to see what would segregate out. Funny thing, about half of them have moderate tolerance to early blight. I'm interpreting this to mean that they probably have PH2. Out of the group, 5 or 6 are more tolerant which I am interpreting to mean they have PH3. Sadly, all of them have been hit pretty hard by Septoria. Even some Peruvianums that I grew because they are supposedly tolerant wound up getting Septoria.
