Below is a picture of one of our colchicine treated yellow besseae's. This flower is on the second growth, and is showing it's full potential.

'Gold Finger' 4N compared to a 2N besseae flavum (originated from the OZ besseae flavum breeding):

What is your goal, Robert? This is pretty nice.

The primary goal was to create some tetraploid (4N) yellow besseae's. And I think I succeeded!

Why 4N yellow besseae's?

- to improve the shape, and size of the existing yellow besseae's. In general tetraploid flowers are larger (both the overall size and the width of the petals), have thicker substance, and often the flowers last longer, so these will be an improvement over existing diploid plants. And once I have a couple of tetraploid 4N yellow besseae's, I can start line breeding them and improve them even more!
- to create tetraploid yellow besseae's that can be used for further hybridizing. When using 2n plants you often run into barriers (you dont get any fertile offspring after so many generations by crossing a third or fourth generation diploid Hybrid by a diploid species or another Hybrid). These barriers can often be overcome by using 4N parents.

Are the 4N tougher to grow like the 2N?
