Deb,With apples, no breeding is necessary. Lots of the heirloom varieties
that have fallen out of favor did so in part because of biennial bearing
tendencies. If you have enough of them in an orchard, the few fruits that
form get hammered so hard by the pests that they will usually fall off in
June drop (or sometime before maturity) and there won't be any fruit at all.
Then even the annual bearers are likely to get started biennial bearing.
When I started planting apples I thought that I had to avoid biennial
bearers. When I realized how that could potentially cut pest pressure, I
decided not to worry. Now I have two areas planted to apples, almost a half
mile apart and I daydream about getting them onto staggered alternate bearing
years. It won't happen, though, because often as not the bearing year is
determined by frosts ruining one year's crop such that the tree puts lots
into making flower buds for the next year.Muffy Barrettsouthern Wisconsin,Mud
on the ground and snow in the air.

.maybe we should be breeding for biennial
bearing in fruit trees...perhaps it would be a way to break the pest
cycle. Probably not practical, but it was just an interesting
thought.
