Hi,
I've had similar problems and am grateful for this discussion. I have a Braeburn and a Gravenstein (no other apples), planted them about four years ago, and was wondering why I hadn't been getting any fruit! I'd read that Gravensteins were triploid but had naively hoped the Braeburn could pollinate (sp?) it. Guess I'll be grafting on some other varieties next spring.
Thanks for the info.

Early apple pollinators
Over time I have made a list of apple bloom times, divided into A, B, C, and D.
Tripoild apples, i.e. 'Gravenstein' and others produce STERILE pollen. These plants have three chromosome pairs instrad of the normal two pair. Nature cannot divide three into a whole number, hence sterile.
If yu have one tripoid tree you should have at least two other trees that bloom in the same or next bloom period. Since 'Gavenstein' blooms in A period you should have two more in the a period (not tripoids). The A bloomin list that follows will give you more than you wnated to know.
