@"MakoDolo"#38 Ktrain I've been taking a look at this subject tell my eyes are burning, and my headaches. ((This is all internet information , I did not acquire it from growing Asian pears.))
First off not all Asian pear trees are self-pollinating. Some are, some are not. Some will produce fruit without cross-pollination, but are much more fruitful with a pollinating pair. Shinseiki and Nijisseiki, are reliably self-pollinating in most regions. Other varieties, such as Hosui, may be self-pollinating, and Nijisseiki, are reliably self-pollinating in most regions. Other varieties, such as Hosui, may be self-pollinating,
They are readily propagated using 8-in or 10 in cuttings. As well as grafting with Scion wood.
It looks like planting a Asian pear seed does not in (any way) guarantee a tree bearing a similar fruit. It does seem more likely pears, can produce a tree with similar fruit then with apples which almost never produce a similar fruit.
Some Asian pear trees are self-pollinating, but most require cross-pollination with another Asian pear tree to produce the best fruit:
Hosui a self-pollinating tree that produces fruit with one plant, but adding another tree will increase the crop size. Shinko is self-pollinating, but it can be improved with cross pollenization.
