A well-constructed pollination compatibility can go into the Reference category with a thread title of pear (or other fruit) pollination compatibility.

Lets see what Scott thinks then maybe collaborate with a bunch of people to put it together as a reference page. Scott has grown lots of pears maybe he has a good idea or has it even partially done.
I will take medium… no problem.
Orient and kieffer are said to pollinate… and i just read that ayers and orient pollinate.
Even though Ayers is said to be self pollinating… it should benefit from orient and kieffer pollen… right… maybe not larger fruit… but more fruit.

Add a couple of columns, need pseudonyms, need species. Anything else you can think of that would be useful?
Variety
Origin
Pseudonym(s)
Species
PI # if in Grin
Average bloom time
Self incompatible
Pollen sterile
Incompatibility with other varieties
Average fruit maturity date
Fruit use (fresh, storage, preserves, etc)
Fire blight susceptibility
Other diseases
Pests
Notes
Kieffer Pennsylvania, United States No alias Pyrus hybrid PI 541714 type 3 bloom
I extracted everything Pyrus from ARS-Grin and have 3906 entries in a spreadsheet. I can tell just looking that many popular pears today are missing from the list.

I kept Moonglow several years without any FB. It was slow to fruit and I never figured out how to ripen it.

@Auburn … thanks… i will stay away from moonglow.
I am thinking my new kieffer and imp kieffer (on callery) trees… + a few grafts of orient, ayers, harrow delight (added perhaps next spring or the next)… will have me in good shape on pears.
@Fusion_power … that would be an awesome resource on pears.

There are people who do well with moonglow but i never was one of them. There are many better pears to grow in my opinion. Someone please post if your experience was different.

I agree. Pruned some fb strikes out of my moonglow this afternoon.

I am going to start a new thread titles “Pear Identity and traits” which will be used to build a spreadsheet of pears and associated traits. The first step is to gather a list of varieties, especially those grown today, and a description of the pears. Here are the items Clark is looking for. Yes Clark, this is your baby. I’m just the midwife.

I’m also up to my eyeballs in things that have to be done yesterday.
Do you have a current list of all pear varieties you have grafted?

That is a long list lets start with these pears that have some resistance to fireblight from this thread Bell Pear aka US84909-391.

Clark, I’m a man dying of thirst and you are offering teaspoons of water. I want a fire-hose!!!
Seriously, I need lots of data to work from. Names of varieties and descriptions in one place are highly useful. I’ll scrape data from orangepippen in a few minutes. Do you have a master list of pear varieties you are growing? Anything on a computer can be scraped and massaged into usable data.
P.S. I should probably tell you that my real life career pre-retirement included being a master data manipulator. I’m pretty good at collecting, storing, massaging, integrating, and extracting useful information from just about any data source.
PPS I don’t recognize Tyson. Do you have descriptive info?

Thanks, lets move this to the pear info thread please. This thread is for Potomac.

Consider adding “Precocity.” That may depend on rootstock but something like Harrow Sweet is unbelievably precocious wherever I’ve grafted it.

Thanks Hambone. I added several fields in the pear identity thread including precocious. Great minds think alike!
