choosing Asian pears

I would appreciate information that would help me choose an Asian pear.

First, pollination: What pollinates and is pollinated by comice in Portland, Oregon? I've checked several pollination charts. One says that chojuro pollinates comice but hosui does not. Others say shinsui, yoinashi, and hosui pollinate chojuro. Doesn't that just mean that shinsui, yoinashi, hosui, and chojuro bloom about the same time? If so, wouldn't shinsui, yoinashi, and hosui also pollinate (and be pollinated by) comice?

Second, fall color: I would appreciate comments about comparative fall color in comice and various Asian pear trees. Online, the information about comice runs the entire range: yellow, orange, red, and brown. Information about Asian pears (except ya li) is almost absent. Do pear leaves ever turn mixed colors like blueberries, or are they always solid colors?

I'd appreciate your experience!

I planted 4 varieties last year, they all turned yellow in autumn, not spectacular.

Marc which pears are those you've canned? And how do you stop them discolouring?

Tahir,

Our family canned those jars. They are a mixture of Bartlett and Bosc pears. I add lemon juice to prevent browning.

Tahir-
Thanks for the color information.

Marc-
I read the newsletter, but did not find anything relevant to fall color or the pollination paradox I asked about. Did I miss something?
Your pollination chart shows the paradox: chojuro pollinates comice but hosui does not, whereas hosui and chojuro pollinate each other. Does this make sense? Or not?

Marc
Is the Hosui semi self-fertile? I was told that it was and in the Edible landscaping catalogue it states that it is. If this is not correct then I am going to need a mate for this tree.
Thanks Karl

I don't see Asian pears exhibiting fall color.

As far as pollination the facts are:

Chojuro pollinates Comice
Hosui DOESN'T pollinate Comice
Chojuro pollinates Hosui
Hosui pollinates Chojuro

There are two issues in pollination: compatibility and time of blooming so one can't say that because Hosui doesn't pollinates Comice and Chojuro does that they can't pollinate each other. It is not the way it works. The same is true in hazelnuts, many times the relationship is not reciprocal or transitive. I have read in a few places that Hosui is semi-fertile, but for heavy crops, always get a pollinator.

Does anyone know whether yoinashi pollinates comice, comice pollinates yoinashi, shinsui pollinates comice, or comice pollinates shinsui?
