I found no difficulty using Meyer as the seed parent in trifoliate hybrid crosses.

F³ seedlings from C-35 Citrange. These are self-pollinated Conestoga 010 seedlings showing mixed leaf types, including trifoliate, bifoliate and monofoliate.  It appears that unlike Conestoga 026, Conestoga 010 may have a percentage of zygotic seedlings.

I don't think I've got any grafted Poncirus+ left, but I have seedlings as well as seeds. I also have Meyer X Conestoga segentrange hybrids, but the latter won't be available until they've been tested for cold hardiness.

If you're interested, you can send me a pm.

Photos of several Meyer lemon X Conestoga 026 seedlings changing leaf colors as colder weather approaches. Some of these seedlings are trifoliate, others exhibit monofoliate, bifoliate as well as mixed leaf types.

Getting a good grasp on the phenomenon of Nucellar vs Zygotic embryony is nearly a requisite for the selection of prospective breeding stock. There may also be a considerable advantage to beginning with the hardiest edible parents. Satsuma are a quite hardy group of cultivars. Low seed production coupled with considerable nucellar embryony are downsides to Satsumas as seed parents. Meyer lemon is hardier than Ponderosa lemon. Meyer produces 100% zygotic seedlings as a seed parent.

I've found Poncirus+ seedlings to begin fruiting at 3 and 4 years of age.

A high seed count zygotic parent may be desirable if it's eventual progeny have a lower count. Do you have any specific breeding partners in mind for further breeding projects?

Excellent, Ilya clear difference in appearance, are you going to test for Zygotic embryony?

Thanks, Ilya, next Spring I hope to use 5* as a female parent in crosses. I actually do have a number of 5* fruit resulting from crosses with Bishop Citrandarin and Conestoga 010 pollen.

Gordon, the largest fruited selections aren't fully ripened. Most of the smaller ones are ripe. These will be allowed to further ripen for 2-3 weeks before testing. This being the first year some of them are fruiting means I'll be testing their seedlings for Zygotic percentages. Following this year there should be a few available for tasting by other interested individuals.

The most vigorous seedling produced 37 fruits which were harvested yesterday. The largest fruit has a diameter just under 3 inches (7,4 cm).



I'm still uncertain whether this tree is a Nucellar C-35, or a Zygotic seedling. I hope to do a seed germination test to help determine its status.
The tree is 5 years old and is fruiting for the first time.


The following photos are of 5* Citrumelo fruits from 4 year old seedlings. This is the 2nd year these trees are fruiting. The largest fruit is 2.5" in diameter.

Thank you very much Kumin. That's awesome

May I add a few questions?

 you just let the seeds germinate and grow and then they flowered after 3 years ?
Or did you try to accelerate the process by grafting the seedlings to a stronger plant or by using another special method ?

Are the seeds speciale? I mean were they selected for being specially fast flowering or for being a good rootstock or something like this you think? (Citrange and citrumelo are mainly use for rootstock right?)

Does someone have images from a seed from an eating fruit from the shops or from your garden (orange lemons pomelos pompelmo mandarine etc) that have flowered ?

Best regards
There was no special precocious breeding stock involved. The seedlings were planted rather closely together, which resulted in upright, tall growth. In most cases, the tallest trees fruited first.
Not all of the seedlings fruited this early. The shorter, more dwarfish trees haven't fruited yet. The trees in the unheated cold frame are fruiting about a year sooner than the same clones out of doors. Many of the first fruits appear following late season blooms.
As far as additional cultural practices, I never prune the trees until they set their first fruits.

3 year old 5 * Citrumelo seedlings tree in flower

Fruits from 4 year old Citrange seedling.

Citrumelo fruits from 3 year old seedling.

It hasn't been determined whether the most vigorous of the C-35 seedlings is a nucellar C-35 or a Zygotic seedling of the same. One earlier ripening fruit had 6 seeds. It made an acceptable drink when sweetened. But, I've also developed a strong tolerance for Poncirus flavors over the years.
The largest fruit measures 2.91 inches in diameter. I've counted 35 fruits on this 5 year old seedling. The fruits are partially hidden and the previous counts were lower.

Conestoga 011 is a Tetraploid selection that is just beginning to transition to the mature reproductive phase. Upon examination of the first flower it's noted that there's no pistil present. This isn't unusual for the first flowers.

011 produces the largest thorns of all my Citrus. This may relate to the Tetraploid state.

Both are grafted, as is all my stock except for seedlings. However, these aren't high grafted.

Conestoga 067 survived 2°F with high winds last December. Many of the leaves are monofoliate.


Conestoga 058 has mostly monofoliate leaves and is less hardy than 067.

I would suspect the monofoliate survivors to have a greater likelihood of being palatable. The leaves of at least one of them has a more fragrant scent than most of the other selections.
On another note, the 5 Star Citrumelo seedlings show considerable variation in fruit size as well as productivity. I was impressed with the precocity of several of them.
5 Star Citrumelo fruits

There are 2 selections that are predominantly monofoliate 058 and 067. 067 survived the past winter out of doors, with modest damage.

Conestoga 010 grafted on Poncirus rootstock has transitioned to reproductive phase out of doors. There's no chance of the fruit ripening on this tree. However, there are maturing fruit in the tunnel. I hope to test the fruit for flavor and the seeds for zygotic embryony. 

 Conestoga 006 trees are also transitioning to mature phase.

Several come to mind: larger fruit, deeper color, fewer seeds, sweet fruit and decreased thorniness. Also diversity of flavors.

Since both parents are of hybrid origin it might be expected to have widely divergent characteristics in their progeny. I'm also inclined to believe the broad genetic base could reduce inbreeding depression.
If a zygotic sibling to Conestoga 026 were to be discovered the next step of crossing Conestoga selections with Changsha X Poncirus crosses might be realized. Again with the goal of keeping a diverse genetic base.

Upon your suggestion I tasted several leaves I detected Poncirus like taste on one, Meyer like on another, but also some unique flavors that were neither of the two. One in particular reminded me of Kaffir Lime leaf taste but less intense. Perhaps some might show promise for their leaf flavors?

Meyer lemon x Conestoga 026 zygotic seedlings. Despite 026 having exclusively trifoliate leaves its backcross to Citrus exhibits monofoliate, bifoliate and trifoliate leaves among its progeny. Quite a few of the seedlings have mixed leaf types.
Although the seedlings may not be hardy to subzero temperatures like its pollen parent, some should exceed the hardiness of Meyer.
