F2 citrange winter hardiness trial
kumin:
Advanced generation 5* Citrumelo seedlings. These photos are of ~5% that have survived -8°F (-22°C) in SE Pennsylvania. These seedlings are a year old.
A dwarf survivor with no damage
A normal size plant with modest damage.

Amazing news between the 058 flower and the 5* survivors. Surviving with damage is still an accomplishment! It doesn't look to bad overall.
kumin:

Can you recap what you have going in your fields currently? I've lost track of the various combinations and generations you're working with.
kumin:
It's a multifaceted effort.
1. Second generation C-35 seedlings tested for Sub-Zero temperatures.
2. Meyer lemon X Conestoga 026 (seedling resulting from the effort stated above.
3. Hybrids between Citrandarins and again selections resulting from the trial in #1
4. Hybrids created between Citrandarins and Citrumelos.
5. Additionally crosses utilizing miscellaneous trees from my collection.
6. Goals: Creating breeding parents with winterhardiness, producing zygotic seedlings that can continuously be field tested for Sub-Zero temperature survival
