I have one orcas pear which is the only pear I have. There's enough overlap in the spring with my japanese round pears to make a constant crop every year. A month ago I noticed other trees had ample pears hanging in other's front yards. 

During a few years in the 90s that I had lived around your area I did lots of scouting around for pear trees. I would go to a japanese pear breeding project on Vashon Island and became a public opinion evaluator for Pete on his new seedlings. With some of the trees I was seeing that the most consistently high producing cultivars were the very few of them that had a very early ripening time. The corollary here is that there was enough vacancy time after August 11th that the tree made adequate recovery of energy for the following spring bloom. 

The one I wanted was such a productive tree it broke branches and although the fruit was not perfect it was good for more looking into and it did have a european pear flavor. Then fortunately Pete was such a nice guy that he released some rootsprouts that formed due to part of the tree breaking. Over twenty years have since gone by and it still proves to be as consistent as ever on it's own roots or completely topworked on another.

I also received some scions from his higher quality japanese pear that had consistently low production at the Island and it continues to be low to nothing here barely north of Portland. It ripens just as early as the previously described sibling thus proving that sometimes the problems of cropping are related to disease or either too late in the previous seasons crop load. 

This year the delicious sibling (after a low set last year) had indeed zero.

My fingers are holding the only 2 leaves of the whole orcas pear tree that have this rust on them. The other twig with rust is quince-c of which (in the ground) is right next to and very much under the orcas but none of it grafted to any parts between each other. All of the quince leaves are bothered the same every year too. The quince never has flowered so maybe this is why.

I did have the Vashon Island productive japanese round pear type doing well prior to my removing the union from quince. Which never got effected at all -so some pears are very resistant from getting it unlike some closer branches of the orcas which can slightly catch on, but still crop.
