Sometimes I think of ourselves being here and with this internet as here to inspire ourselves. Here means, for all intensive purposes, the proximity to the coast and cool spring wet weather. Some of the things we know avoiding when it comes to what kinds of things to avoid and one of those is anything that flowers earlier than sweet cherry due to lacking pollinators or the partial infertility of the specific cultivar. And speaking of infertility and sweet cherry, I wanted to post a link on 'Royal Anne' sweet cherry as studied for the level of fertility it has and normal spring temperatures don't seem to be a requirement for the RA cherry.

The option to download two PDF pages related to RA cherry and fertility information:
journals.ashs.org/cite/$002fjournals$002fhortsci$002f20$002f5$002farticle-p913.xml (circa-1980)

They list a stand out cultivar of a pollinator for Royal Anne which goes a long way of how or why we don't necessarily need to blame the bees all the time. The bottom line is we need to continue testing, or the very least, keep bringing up historical data all the time so it never gets lost. 

Next idea:
sciencedirect.com/science/article/pii/S096098222031890X

This recent discovery of DNA on yeast, adequately explains the nature of DNA, that all organisms evolve 'classes', meaning separation of life materialistic forms based on the speed of the DNA migration speeds, and the article is just one way. I also think it has application why it is that plums dominate in widely specific crosses such as 'Nadia' and other cherry x plum and apricot x plum offspring towards plum, assuming speed is favoring plum. If correct it's safe to assume all hybrids with plum are predominately plum. 

The theoretical here is that apricot and sweet cherry are slow. The proven here is that 'Royal Anne' is a sweet cherry and has remained popular through the ages in maritime British Isles and here for being so simply reliable during flowering. The latter of which makes sense over any other cultivar (and in light of recent info in last link) for making new 'sweet cherry' x 'apricot' hybrids from it. 

It's also hypothetical that many readers won't know what plums crossed to other apricots and cherries taste like (plum dominates) but still might agree or appreciate (somewhat) a little bit about speciation.

Here I'm telling Anonymous who posted December 1, 2023 at 12:45 PM at the following blog;
https://johannsgarden.blogspot.....k-for.html
..who the blog owner references Westwood et. all and his 1989 release regarding inter-operations and experiences between a certain apple cultivar on m26 verses pears.

There, while not being specific enough, I'm leaning into telling a person Anonymous that those malus 'winter banana' seeds might be true to type. The context of this is still "pacific-conditions-for-breeding" because it so indicates the person is involved in education or research at UW dot edu or otherwise volunteering at Mt. Vernon WA.

What I'd like to furthermore submit is that seeds collected from different environments as a seed-lot can be completely different from one another based on seed-lot. This is an on-topic discussion where just now I submitted my own answer to it. When people read this last idea of mine concerning apomixis in fruit breeding caused by irregularities in pistillate reactivity and genomic issues it's often frowned upon by the observer that says "oh no, what about the bees?". To which one must realise that bees don't fly west of the Cascades.

Well they do for apples but our prunus crops suffer from the loss of flight in wet weather. So I'll concentrate on prunus. Here are a few things that pro-create (ie. without bees) all by themselves followed by things I'm still testing if they pro-create.

Done testing list;

Double flowering Flory peach (peach x unknown)
Owen T plum 
Sugar Twist (registered 3 way interspecific/intraspecific)
Splash (apricot/plum by Zaiger)  
Nadia (plum x sweet cherry)

In the Process of testing;

Shiro (4 way plum)

Many of these cultivars listed implies they have viable pits because I have yet to have, for example, Splash seeds to be released to me from the Hills NE of me. Prunus cultivars often have blank seeds when pollinated from sources outside of the normal course of the population. For example the 'lydecker' hybrid plum that I have sheltered from rain is highly productive with prunus tomentosa pollen. The fruits are good. The seeds are blank.

More insight can be found by using the forums search bar to locate the word " paradox ", and of itself will yield another linked to article through professional eyes more than I have. It being full of insights into the ancient 'asexual' mode of production than we can ever have imagined inside of my grandfathers generation.

If there anything more to the list to add I can only tell you that to see what qualifies is trying to see the attributes of the parents about whether or not they are capable of selfing. For example domestic apricots types are viable selfers through pollen from the same flower. They will not qualify as internally promiscuous individuals unless the individual wishing to be listed is incapable of producing pollen from it's own anthers.
