Re[2]: Descriptions

        Regardless of WHEN the cross was made - genes are genes - I would think 
it would be the generation LEVEL which would determine how important a 
contributor each Iris was to the end result. 

        If you wanted to re-create part of the line of breeding by performing 
the same crosses - there obviously is no guarantee that your results would be 
similar - and the rate of deviance would increase tremendously with each 
successive level of the original parentage.

        It is amazing to think that Iris from the forties could be only 2 or 3 
generations removed from some of today's introductions, when easily 25 
generations could have been bred in the same time period.

I have a triple stalk in one fan off Belvi Cloud - it really looks like "deep 
branching" rather than three separate stalks - too early to get a bud count but 
it promises to be interesting.

IF I read the pod parent above correctly, it is a fourth generation 
cross. Is that correct? so while it could have been started 30 years ago 
with (Grand Canyon x Violet Harmony Sib) it could also be as recent as 
8-12 years ago (giving 2-3 years to each generation). Is that true too? 
Shows you how little I know...
