over my head genetics

Hi everyone, I found this page while looking up how to cause mutations or inbreeding in daylilies. It is over my head for the most part, but maybe someone could brake it down for some of us here :)

In the last part it discusses that a blue daylily will come from crossing a blue eye with a white. Interesting stuff here...Enjoy :)

Here is a link that might be useful: genetics of daylily color

The suggestion that blue could be produced by selecting using crosses of 'bluish' eyed plants with 'near-whites' was made quite some time ago. I think hybridizers who tried that strategy were not successful.

A reasonable strategy is to select as parents plants with the most 'bluish' flower colours and cross them together. If one has only one such plant then crossing it to a near-white is reasonable, but then so would be crossing it to a lavender or perhaps even a pink or dark bluish-purple. There is no easy wasy to get bluish daylilies except to select generation after generation for more blue in the flowers.

There is an idea tha if one can produce a 'bluish' eyed plant then one could select parents so that the eye came to cover the whole petal. I think that will be difficult as the petal in most plants, including daylilies, has two slightly different parts (lower half versus upper half - not top versus bottom of the petal). The different parts are important for developing the flower and for what happens when the flower bud opens and the petals expand. Eyes typically do not extend much past the half-way point on petals and may be linked to the differences in the two petal parts.

If one was to breed for petals that were all eyes one could do that by keeping the size of the petal large and selecting for wider eyes and smaller petal remainder while maintaining the petal length. Or one could reduce the size of the petal so that it was only eye. In that case one would select for smaller petal remainder while maintaining the eye width (selecting for shorter petals that were all eye). The two strategies are not necessarily genetically equivalent.
