Potato leaf x silvery fir tree foliage = ?
« on: 2022-07-23, 02:18:15 PM »
I haven't been able to find this in previous threads, but I just did a cross: PL mother, silvery fir tree father. What do I expect in the leaves of the F1? I've been using PL mothers so I can be sure in the seedling stage that the crosses took - I'm mostly dusting super exserted stigmas rather than emasculating - and I've realized that may not help me with these crosses.

I guess I'll find out this winter either way.

Carrot leaf foliage is a modification of regular leaf. I would expect the F1 to be similar to regular leaf. I bet Andrea Clapp would know for sure. She seems to be on facebook and instagram.
Western Montana garden, glacial lake Missoula sediment lacustrian parent material and shallow 7" silty clay loam mollisoil topsoil sometimes with added sand in places. Zone 6A with 100 to 130 frost free days

Oh good, so as a pollen parent on PL it should be apparent whether it worked.

I'll see if I can hunt her down.

Thank you!

No answer from my query, but I did find this:

https://www.tomato-talk.com/forum/main-forum/1449-regular-leaf-vs-carrot-leaf-vs-potato-leaf-which-is-dominant-over-which

Quote
The results from Carrot Leaf X Potato Leaf cross:
F1 – 12 plants total germinated = 100% Regular leaf

F2 – 546 plants total germinated
RL – 343 plants = 62.8%
CL – 73 plants = 19.6%
PL – 78 plants = 17.6%

F3 from PL F2 – 8 plants = 100% PL

F3 from CL F2 – 75 plants
CL – 58 plants = 77.3%
PL – 17 plants = 22.7%

Conclusions:
RL is dominant over both CL and PL – expected
CL is recessive to RL but dominant to PL – learned
PL is recessive to RL and recessive to CL – learned.

Interesting experiment. Just wanted to comment that the % are calculated wrong in the F2, there were only 13 and 14% of CLs and PLs.

PL is recessive to RL and recessive to CL – learned.

Also, if the PL was recessive to both RL and CL, there should have been close to 25% of PLs in F2. And maybe there was, the discussion continued to potato-carrot leafs later. Just that the numbers reported for the F2 generation (i.e. 78 = 14% PL) do not support this conclusion.
