Are resistant varieties developed from existing resistant varieties by conferring resistance genes or does the trait just appear randomly in seedlings?
I was wondering whether it would be worth planting a resistant variety or just playing around with random peach stones.

What do you want to improve in existing varieties?

What do you want to improve in existing varieties? Well not much that can't already be found in others. Just early, reliable ripening in a cool climate (northern England), later flowering, less dormancy requirement over winter and decent level of resistance to the most serious diseases likely to be encountered here. |

I kept 3 seedlings with healthy leaves after my leaf curl resistant peach Thorseng. These 3 seems to be even more resistant than the mother plant. Now I'm waiting for the first fruits one of these years :-)

Back in 1906, someone found that peach leaves with eglandular bases were less likely to suffer from curl. Leaves with reniform glands were most likely to get curl, and those with globose glands were intermediate in susceptibility. You can google to see what the leaf bases look like. I assume the glands are present on the first leaves of a seedling, so that you could toss out any seedlings with glands.
