Cold Hardy Citrus / Re: F2 citrange winter hardiness trial

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

Conestoga 067 survived 2F 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.

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.

Crossing Citrandarins with Citranges and Citrumelos should broaden the genetic base while conserving genes for palatability as well as cold hardiness. In the F generation there appears to already be a lowering of vigor in a percentage of the zygotic seedlings. In the Meyer Lemon x Conestoga 026 hybrids there appear to be fewer weak seedlings.
I would expect the depression of vigor to likely worsen in the F selfed generation.
Further trials should shed more light on this matter.

To this point most have a lighter pubescence than Poncirus, but all have at least a faint fuzziness. The supposed C-35 has less, if any pubescence.

Walt, my "Holy Grail" would be a zygotic Conestoga series tree. This would allow for the production of hybrids between a subzero hardy parent and the other parent being Morton Citrange, Thomasville Citrangequat, etc. Bishop Citrandarin has a percentage of zygotic seedlings, but most appear to be rather weak.

Recent photos of various seedlings, grafted trees and fruits:

This tree may be a C-35 seedling. It's got approximately 10 fruits at 5 years of age. The fruits are 2" (5cm) in diameter.

1279 Citrandarin fruits are rather small.



First fruits on Conestoga 006.

Poncirus Plus fruits.


First fruits on Conestoga 021.

First 010 fruits.


Grafted Bishop Citrandarin



Grafted Dragon Lime


Grafted Conestoga 067


Grafted Flying Dragon with fruit


Grafted 5 Star Citrumelo

Recent adaptations allow the Citripots to be held in any preferred position.

I find late season growth quite vulnerable. Spring growth has a chance to lignify better and survives much better.

My next adaptation will be to mount the square tubing on a turntable, allowing rotation by hand to remove the lower thorns, as well as to access the best exposed part of the rootstock stem.

Rootstock in Citripots is prone to fall to the side. Rootstock can be awkward to budgraft in upright,or even flat position. This is a crude positioning apparatus to secure the rootstock in a favorable position while budding or grafting. Upon using it I should be able to critique its ergonomic pros and cons.

The fruits differ quite a bit. Poncirus fruits on very short stalks, perhaps a bit like Peach. These have longer stalks a bit more like Plums. There's minimal, if any, pubescence on the fruit. Initially, the fruit were smaller than Poncirus, due to later bloom. At this point they are about equal in size, but likely to soon surpass Poncirus.

My assumption is that they're carbon copies of the c-35 parent, but I have no proof of it.

The supposed C-35 fruits continue to grow larger.

Citrus General Discussion / Songbirds nesting in Poncirus
« on: July 11, 2023, 07:03:52 AM »
I've noticed 8 Robin nests among my Poncirus and Poncirus hybrids. One nest is only 30" above ground. The birds appear to be quite at ease due to the presence of thorns. I've never seen any of the neighborhood cats in the Poncirus trees!

I've just discovered an additional 5 year old seedling tree with 10 fruitlets. These are the first fruits for this tree. I'm not totally certain if this is a zygotic sibling to the remainder of the cold hardy test survivors, or Tag along C-35 that survived via a root graft to a hardy selection that subsequently died.
This tree's in the Cold frame/tunnel and has avoided the harshest cold winds.
The fruitlets show little, or no fuzziness exhibited by Poncirus and some of its hybrids.

I expect it's hardiness to be between Changsha and Bishop.
