Other sources will tell you that Seckel is self-fruitful

It's self fruitful for me in NorCal

As far as the Dana hovey pear pollination goes (Seckel is listed as a viable pollinator)

I planted a Moonglow "friend" next to my Seckel..

November 2010, planted 2 Bartlett-type, a Seckel & MoonGlow. This Spring I got the 1st flowers. No fruit set. Hopefully next year. In comparison to all my other pomes or stone fruit trees which all flowered and produced something by the 2nd year, the pears are fruitless so far. The trees are handsome and vigorous, but slow. I am understanding that this is common.
