Different colored leaves

[Mudman]

I was just looking at my seedlings and noticed that I have some of the same varieties that are right next to each other and have much different colored leaves (lights green and dark green). I thought there was a gene that determined the shade of the leaves so I am wondering if this is an indicator of instability.

All plants of the same variety should have the same foliage color.

And yes, there are many genes that control foliage color, from dark green to grey green to yellowish, etc.

When you have time you can go down through the list of genes in the link below, from the Rick Center, and see how many genes there are for foliage color:

Way ahead of you Carolyn, I went through that list this morning during my break at work.

So one of the varieties that is showing these differences is P-20 (OSU Blue) and I expected that, but the other one is Brandywine Yellow that I got in a trade. Both are PL, but one is kind of bright green/yellow and the other is medium green.

Fertilizer.

I have seen seedlings in the same cup have somewhat different colors of green if the fertilizer is uneven or washed out.

I have not fertilized per say, they are both sitting in identical cups with MG potting mix. It is possible that the fertilizer in the mix is unevenly distributed though.

Since you got your Yellow Brandywine seeds in a trade and the foliage colors are different for the two plants, and you say that it's probably not a fertilizer issue, if it were me I think I'd wait to see if both plants are indeed Yellow Brandywine.

I can't see uneven distribution of fertilizer in the medium leading to all the foliage being on the yellow side/ Does your MG potting mix have fertilizer in it already and if not what are you using to fertilize the plants, meaning solid or liquid fertilizer.

Could be a stray PL seed for one of them, one of them could also be from crossed seed.

No way to know.

And no, you didn't beat me with the TGRC gene list, I had it in my faves already but didn't get around to posting it until this AM. My faves list is insanely long and I spent too much time last night trying to find it.

I really should delete almost half of the links I have, but I think about it and then don't do it.

The MG has some fertilizer in it and I haven't feed them anything at all yet. They are about 3 weeks old and I was planning on giving them some liquid fish emulsion but they are growing better than ever so I am still waiting.

Tell me about it. In my Firefox browser I hit the bookmark tab and it goes to the bottom of my screen, not sure what happens when it goes past the bottom. Oh well.

It is amazing just how different the leaves of different varieties look at the seedling stage.

I'll tell you what happens when you've reached the capacity of your faves. At least I get a window that pops up and says no room for what you want to save, or words to that effect. And then I DO have to go back and delete some links to make room.
