Hybridizers have been trying to develop true yellow African violets for several years with varying results. The first officially recognized yellow African violet debuted in 1992 (I believe it was African violet ‘Majesty’ hybridized by Nolan Blansit – if you can confirm or correct me, please do!)
Some very promising work with yellows was done by David Senk in California who has produced some unique and exotic African violets. Below are some results of his hybridizing efforts working with the yellow color trait as well as longifolia leaf form.

I started hybridizing for a good yellow African violet myself back in 2004, and have been working with yellows on and off ever since. I know I’m a little bit of a perfectionist but I haven’t hit the grand slam yet and so I haven’t registered any varieties yet. When I come up with a yellow African violet that is a good show plant I will definitely introduce it. But, until then, you can check out some of the hybrids I’ve produced from African violets carrying genes for yellow flower color here.
If you are interested in cross-pollinating African violets you might want to try hybrizing gloxinia, too – they are just as easy to pollinate and produce a lot seeds readily.
