Galina's Yellow x Snow White F1

[salix]

Thanks, Sue - it sure beats Yellow Snow!!

I wish I knew what Joe Bratka used to develop Snow White and Ghost and Rabbit and Super Snow White, but I don't b/c he never told me, actually I don't think I ever asked.

But it seems to me he would have to start with at least one parent being Mirabell or Mirabelle Blanche or possibly Coyote or even a white currant b'c I know that he used currants in his breeding b'c he said he thought that the crosses took more easily.

And I'm embarrassed to say that a couple of months ago he e-mailed me and before he never had a computer, but I suppose I could ask him if it makes any difference to you folks working with that cross. I just haven't gotten back to him after my first response to him saying I'd get back to him, and haven't. Sigh. But I also know that he may tell me nothing.

So let me know if you want me to try, if you think it might help.

"Mine sure don't look as big/bushy as yours...." Sue, if you click on that picture to enlarge you'll see that each pot has 4 plants in it to separate the RL from the PL, so not as bushy as they might appear. I will transplant again later and decide at that time how many of each I am able to grow out.

Carolyn, with 50% PL and 50% RL in the F2, do you think it is possible that Snow White is a Cc RL? Would this mean that one of the parents of Snow White was potato leaf? I am not very good at genetics.

Linda, if you look at Tania's Offtype thread I just went through this with a couple of posts.

OK, back to SW X Galina's before I forget which cross is being discussed.

Galina is cc, no problem with that

Snow White is RL, so could be either CC or Cc

if SW is CC genotype, then CC X cc Galina's and all should be RL

If SW is Cc genotype, then Cc X cc Galina's gives 1/2 PL and 1/RL

Which is what I think you'r getting, I didn't go back to check.

So if we assume that SW is Cc, then does it suggest that one of the parents of SW, if joe used only two parents, which we don't know, was PL, then no, we can't predict the parents of SW b/c it could have come from the following cross:

Cc X Cc, two RL parents, both heterozygous for leaf form and both RL, no PL parent b/c:

C c

C CC Cc

c Cc cc

where 3/4 could be RL and 1/4 PL and 2/4 will be Cc

CC X CC gives all RL
CC X Cc gives all RL
cc X cc gives all PL
Cc X CC also could be two RL's that could give 2/4 Cc RL's and no PL parent
CC X cc gives all RL's

It's all statistical. In the post I just did for Tania in the off type thread I discussed how I got no genetic segregation from the F2 seeds of Black Krim X Galina's and that after growing out 12 plants in each of two seasons. No leaf form differences and no fruit differences.

I then concluded by saying that moms know they have a 50% chance of having a boy child, but tell that to the mom who has had 4 girl kids one after the other.

Summary: If Snow White is Cc one can't conclude that a parent was PL b'c there's more than one way to get a Cc genotype and both parents could be RL and have that happen.

Very nice explanation, Carolyn. I went back to find the other thread you were talking about and read that too. Thank you.

I hope that the Galina X Black Krim F2 seeds (from the F1 I am growing this season) have more segregation than what you got. I don't have room to grow too many of them!

[lefty_logan]

I started 3 f3 seeds today.

Galina's Yellow X Snow White F2:
March 30, 2010 - planted 3 RL and 4 PL plants outside, along with one RL F1.


Galina's Yellow X Black Krim F1:
March 30, 2010 - planted one RL F1 plant outside.

Linda,
I am also growing out both and the leaves of the Galina x Black Krim are pretty pale green compared to other tomato seedlings. How do your seedlings look?

[Linda10]

Sue, I just went out to the garden to check. It looks the same as all the plants around it. I'll be posting a report tomorrow with pictures if it is not raining.

[Linda10]

Okay, Sue, here is the promised report with pictures.

Galina's Yellow X Snow White F2:

April 13, 2010 - 3 RL F2 plants
Plant RL1 - 16" tall, has small open flowers (right side)
Plant RL2 is 9" tall (middle)
Plant RL3 is 11" tall (left side)

Thanks Linda...they look real good. I am envious of your big plants and your nice tomato growing weather. I am still at least 5 weeks from putting anything outdoors and then it will be in pots.

Linda I like straw also(previous pics). As mentioned when I saw you last friday that stuff is a chiken magnet! After going to my mom's last weekend I realized there was at least a 50% atrition rate for things planted outside the fenced raised beds. Darn chickens.....however, you can't beat fresh free range eggs! no pun intended.

[Linda10]

LOL, Vince. I know what you mean! Enjoyed your visit.

Galina's Yellow X Snow White F1:
Plant was very vigorous, giving an abundance of yellow-gold fruit at 0.2 to 0.3 oz. Yellow epidermis. Flavor started out at 7.2 in cooler spring, but increased to 8.0 this week with warm weather. This is a very nice hybrid.

Galina's Yellow X Snow White F2:
RL #1 gave fruit the color of Snow White (which is pale yellow here) with clear epidermis and averaged 0.2 oz each. Flavor was average. Plant was vigorous.

RL #2 died early in the season.

RL #3 gave yellow-gold fruit averaging 0.2 oz each. This one looked the closest to the the F1, but flavor was not there.

PL #1 gave the smallest fruit, averaging 0.05 oz each with average flavor and yellow color.

PL #2 gave yellow fruit at 0.1 to 0.2 oz in size. Average flavor.

PL #3 gave gold fruit at 0.2 oz, but had below average flavor.

PL #4 was my favorite. It was pure yellow with yellow epidermis and pale flesh. It also had the largest fruit at 0.3 oz. This was the best tasting of F2's but it still wasn't as good as the F1. I rated it at about 7.4 this week.
