I should have pointed out that if the sectors are genetic they would be evidence of what are called somatic mutations, meaning changes in the genes that occurred in the body of the plant rather than in the sexual development (in the gametes - pollen and ovules). Also that in plants, more or less unlike animals, somatic mutations can be inherited. So if a flower shows a sector on the petals, sepals, etc., then using pollen from the stamen attached to the sectored petal or sepal has a chance of producing seedlings that carry the new mutation throughout their bodies. However, to see that mutation in the seedlings one would have to make the appropriate types of crosses.
Even if the sector was genetic it can be quite difficult and laborious to produce a plant that shows the new mutation. It is always much easier to do this in diploids rather than in tetraploids. Producing a plant that is homozygous (pure breeding) for the new mutation would usually involve growing several hundred first generation seedlings from pollen of the sectored petal or sepal and then making 10 to 20 seedlings by self-pollinations from each one of the first generation seedlings. This in itself is difficult in daylilies since most diploids are self-incompatible. Self-pollinations fail and daylilies suffer from high inbreeding depression so any seedlings produced from successful self-pollinations tend to die or are weak. Far more than 10 to 20 seedlings would have to be grown from each first generation seedling in tetraploids.
