Color traits?

rredbbeard(SE CT USA/zone 6)December 15, 2011

I have 2nd and 3rd generation plants from my original single orange clivia, and successive generations are getting more yellow than orange, which is fine with me. Although I have yellow clivias too, they have never cross-pollinated. First generation is solid orange. Some of the second generation are half yellow with orange tips on the petals

Many of the 3rd generation seeds from the original orange line show no trace of red in the leaves, and it seems like they may be pure yellows. Has anybody seen this kind of 'color drift' in their clivias? There must have been a yellow gene in the original plant...

Your original plant was probably a cross between an orange clivia and a yellow one. Yellow clivias have a gene that doesn't produce the pigment that makes clivias orange. A clivia only needs one of those genes to have orange flowers, so a cross between an orange with two orange genes and a yellow with two yellow genes will produce 100% orange clivias with one orange and one yellow gene. If you cross those plants, half the offspring should have two yellow genes and will have yellow flowers. That's classic Mendelian genetics.

Clivia genetics are actually a little more complicated than that, with several different genes contributing to flower color. There are different kinds of yellow clivias that have different yellow genes, called group one and group two yellows. If you cross a group one yellow with a group two yellow, you will get an orange clivia. There also are yellows that arent in either group. There hasn't been a lot of scientific study of clivia genetics, so the issue of color inheritance is still a bit of a mystery.

Yours could have unintentionally cross pollinated as well, especially if they are outdoors :)

Or it could be hetrozygous as Ohiofem said.
