Galanthus January 2011

With birds there is a sex-linked yellow where the female is yellow dominant

Yes Anne it was you.

I think maybe Mark is referring to me. I crossed Wendy's Gold with Lutescens and got about 60% yellows. The genetics must be a little bit more complicated than a single recessive gene in each to get that many. They are nice yellows but unless they prove particularly vigorous or have some other feature I haven't seen yet, they will not be worth naming. One of the clones is shown here, with Wendy on the right.

Annew, if you have too many of your yellow seedlings I am more than willing to grow some in my garden

Nice to see her Tony, way ahead of the clump in my garden, it's like having two bites of the cherry

[Gerard Oud]

If anyone knows whose Wendys Gold mother? We are one big step further!
Ifs possible you have more chance on yellow clones with Wendy's mother, she has proven to produce yellow ones.

[Martin Baxendale]

Anne, I'd be interested to know what the vernation of the leaves are in your yellow seedlings. E.g. are they all plicate like Wendy, or applanate like Lutescens, or in between, or a mix? And which parent do they generally speaking look most like? I'm looking for genetic clues here of course.

By the way, Mark's post:

Could be taken in all kinds of ways!

Lovely Tony

I thought you said it rained all day yesterday - it looks like the a blue sky behind Yvonne Hay. 

Mine (thanks) are not open yet it is not warm enough

Ian it did rain all day yesterday and was dark.

That plant had looked ready to open for over a week with no result so action was needed.Clearly you do not use my technique of sitting the pot on the central heating boiler for an hour and then photographing it against a grey card!

Joy Cozens beside Cedric`s Prolific
still looking good

[annew]

Martin, they are a mix - a 'swarm'. everything from pure applanate to fairly plicate.

Anne, you may not think that any of your yellow crosses are worthy of cultivation but I think it is really impressive that you have succeeded.  Presumably the next thing to do is to try to breed a yellow analogue of a virescent snowdrop or a yellow version of something like Trym?

Already on to it, but in that case the other parent is green, so it would probably take 2 generations.

[Maggi Young]

oops, posted this in the wrong thread, had to redo it!



Will the next "move" for you not to be making further crosses of yellows to make F3 etc crosses, Anne?
Thinking of how the F2 and further generations of Crocus x gothenburgensis are so much nicer than the original cross, it seems to me the the yellows might be improved by more crossing and back crossing......  Huh ( If one wanted to do such a thing......  )

Right, well that probably rules out Wendy being polyploid. As you say, a yellow virescent - you can't actually say a yellow virescent, can you...flavescent? - would be a long slog, crossing a yellow and a virescent then back-crossing the seedlings with a yellow. Not sure of the chance sof success, but percentage wise must be low so a lot of seedlings needed.
