My yuzu seedlings mostly look the same but there are a few extra squat ones. Are these crosses? ibb.co/HG7KvwT |

I don't see anything remarkable but you must know that yuzu is not fully true-to-type. You can have something like 20% of zygotes.

It appears that the squat seedling could reach a fruiting node count with much less height. That would be a positive for potted culture or in ground plantings where winter protection would be needed for survival.

ibb.co/6Rsvp47I'm seeing almost all monoembryonic seedlings. Not what I was expecting.

If it is right, it could be very interesting. You could verify taking few out the subtrat.

It happens very often with Yuzu, there is one embryo per seed,but most of them give true to type nucellar seedlings.

My Yuzu N°3 seedlings show different appearance, some have the typical alternating first leaves like Poncirus and its hybrids. The seeds are from open pollination, so I suspect that a Poincirus hybrid was the pollen donor. However, some seedlings also look like citrus. Overall, they are very different from the yuzu seedlings I have from purchased fruits. |

If yuzu is mono embryonic and mostly true-to-type could mean that fecundation is mainly auto-fecundation like citrons and pomelos.
Therefore strongly homozygous.
Just an Idea...
I have a lemon tree, "petit citrons de la Réunion", wich is true-to-type. The pistil is forced to pass through the (mature) stamens to come out.

I suspect that this is also the case with Ichang papeda. Stamens and pistils are always so close together that self-pollination is very likely and difficult to prevent.
By the way, Yuzu x Citrumelo, which is newly offered in some nurseries, is also a Yuzu N°3 hybrid (N°3 x swingle 4475). Maybe it is also that N°3 produces hybrids more easily?
Just an idea, it could also be due to the yuzu variety....

You ask, are they crosses? Probably not, anyway it is way to early to draw a conclusion.
