It produces a fairly heavy crop of huge fruit annually, and I had them ship me one final yr so I might attempt it since I am by no means in south FL in the best time of yr to catch them. This was apparently a bit bigger than common, however not the most important, weighing in at simply over 3 lbs:
Right here it’s with a store-bought Ataulfo for comparability:
That is what it appeared like totally ripened (possibly even a day or two over-ripe):
I sadly did not take any images of it reduce open (we have been tenting and my palms have been means too sticky, and it was devoured too quick), however here is what the seed appeared like (the compass has a scale):
The seed was mono-embryonic and already very a lot sprouted, that is what it appeared like as quickly as I eliminated the seed case:
I am rising the seedling in my greenhouse and it is completed high-quality thus far, however rising very slowly.
In order that brings me to the purpose of this thread, does this fruit appear to match any recognized cultivars? My first guess was Madame Francis as a result of the fruit form appears roughly appropriate, however (1) these appear larger, (2) they do not flip as yellow when ripe, and (3) from what I can discover Madame Francis is normally polyembryonic.
With out an apparent graft union, I am considering possibly this was a zygotic seedling of Madame Francis. Some other concepts?
