more production... vs. perennial ag.

I recently spoke with a soil scientist involved with short rotation
forestry research. Hybrid poplars for fiber are now being grown by a few
OR farmers as an alternative to grass seed production. When I
asked whether coppicing was part of the study, I was told that genetic
turnover is of highest priority and so new "improved" cultivars are planted
every rotation. I have also read on various occasions that the high
annual cull rates (40% +) in many dairy herds are a neccessary part of herd
improvement. These are 2 examples of what seems to me to be a basic drive in
industrial agricultural research for as rapid genetic turnover as possible.
How important is rapid genetic turnover to farmers... is rapid genetic
turnover a fixation of the ag. research complex that is out of line with the
goals of producers... Ex. Some dairy operators find keeping cows 5+
lactations is much more profitable than the standard lower # of
How does this drive for genetic turnover affect the prospects
of the perennial cropping systems being touted by some as the future of
Are there significant flaws in this rapid genetic turnover agenda ?
Do the benefits out weigh the flaws ?
