Ansu apricots are believed to be native to north north-east China and southern Mongolia. Rainfall within the area increases from 0" to 2" during spring and peaks around 2.5" during summer. Ansu has been extensively cultivated in drier regions in Central Asia and the mediterranean regions of the Middle East and Europe. Disease resistant cultivars, particularly against brown rot and bacterial spot, will be necessary in wet climates.

Manchurian apricots are native to North Korea and the Manchurian region. Rainfall within the area increases from 0" to 3" during spring and peaks at 3" to 6" during the summer. This leads me to believe that their fruit are more resistant to disease, but no one really talks about them or their hybrids.




Prunus sibirica, Siberian Apricot
Zone
2?
Pollination
self-fertile, self-sterile spp
Blooms
(overall) very early spp
pH
6.1 - 7.3 (preferred), up to 7.8 (acceptable) spp

Siberian apricots are native to the border of eastern Russian and east Asia. It resides north of the native region of P. armeniaca and west of the native region of P. mandshurica with some overlap and hybridization with them both. Rainfall within the majority of the area is dry, similar to P. armeniaca, but a reasonable portion experiences high rainfall as well.

Katy is often considered to be a southern apricot but there are complaints about how it rarely sets fruit, and no one seems to disagree. For this reason, I'm going to list it as a 400+ Chill Hour cultivar in spite of others usually listing it as a 200-400 Chill Hour cultivar.

Brookcot blooms later than Morden 604, Debbie's Gold, and Westcot (a few other ultra-cold hardy cultivars). It doesn't mention by how many days, so it could end up being by a fairly insignificant amount. The tree has survived temperatures down to -48F and may be able to push further.

Morden 604

The flower buds of Morden 604 have been reported to survive down to at least -40F. As cold hardy as this tree is, it may consistently bloom too early in Edmonton, Alberta to regularly survive spring frosts (according to only one report). However, the tree was bred in Morden, Manitoba. Spring temperatures in Edmonton are cooler and the climate is at least a little more stable, implying that it would have a better chance of fruiting in Edmonton than its place of origin, but are the differences between the two cities significant enough to matter? Why would they release the cultivar if it rarely fruited in the first place? As mentioned, its performance in Edmonton was only based on one report.
