As we see growing popularity for striped pears we are also left with many unanswered questions. We will grow them out and find out more.
Are either of these the pears @tonyOmahaz5 has?
@PharmerDrewee are we any closer to finding out if these are red Zao Su Li
Which do you have Clark?
I managed to locate both red striped and green striped for grafting this year. Iām suspecting there are others and that we can make more with hybridization of these pears. Iām trying to learn more about them now. I think we need to do some experimenting. We should be able to send scions next year. I can send you a partial stick of each if you want to see what you can do with them.
I have a small tree grafted with a scion from Tony. It is suspected to be Red Zao Su Li. I also have the double flowered Vermont Cabot. Wonder what a red striped pear with double blossoms in spring would look like? For that matter, what would a red striped Warren look and taste like?
You and @tonyOmahaz5 and @39thparallel are going to get me in trouble with growing more pears. Iām not sure where Tony has been lately. I am only adding 15-20 more types this year.
A man needs something to be passionate about. Pears are a good choice. 
I have several different pears with unique traits that I would love to combine. Double blossom, red stripe, fireblight resistant, large delicious pears, red/orange fall foliage
Iām hoping these are somewhat fireblight resistant. @Fusion_power my suspicion is The very rare Yu hong red striped pear yu hong is the pear that came from sophia that Tony shared with you. Iām pretty sure red Zao Su Li is a different variety now. Iām confused and will need to grow them out to be sure.
I definately have
red Zao Su Li
Schweizerhosen
I definately dont have
red yu hong
It is not very likely. Fireblight resistance seems to be a quantitative trait where multiple genes contribute. Only highly selected lines seem to show it at a high level. We will eventually have to incorporate fireblight resistance from callery into edible pears. Why? Because it appears to have a slightly different genetic mechanism than the resistance in most other pear species/varieties.
I dont know chinese, though i know
Li = pear
Yu Hong = Red Striped
What i read in european markets is
" * A special Chinese variety of Asian pear with dark red fruits that are streaked with yellow.
You found it on a Hungarian website. It appears to be circulating in Europe to some extent. My son lives in Romania and can probably purchase a tree.
To me it seems the only difference is Yu Hong is a sport and has red leaves. If thats true your tree should have red leaves.
My tree has red leaves. If you dig around, there is an article on the red color in Zao Su Li which describes the gene causing the color. It is an unstable mutation which can revert to normal green. As such, it will probably produce green offspring. Red offspring would probably not occur.
Than we think yours is yu hong. Iām still confused i think there is much more we need to know here.
Iām not convinced Yu Hong is the same as Red Zao Su Li. Fruit shape appears to be different. However, it really does not matter. I have whatever Tony sent me last spring. I transplanted the tree in the corner where my driveway intersects with the road. Everyone driving by will see it.

The OR has been pretty busy lately with the 10 hours day. Here are a few new Asian pears that I am going to graft this weekend.
This Ugly pear is unique.
Tony
Those look very cool. We will have to touch base soon. Iām going with @39thparallel to demonstrate grafting for a group in may. You should go with us if it slows down for you.
If you want to tantalize yourself, look up a pear named āPremP109ā.
Tony, is that first pear Nanguo?
Very interesting but i have grown āreddy robinā for years. It was released in 2012 over 13 years ago.
