Hi Joe,
Thanks for the response. Can you tell more about MAS applications to
rice? I once talked with a representative from Keygene, a breeding
company here that applies MAS and claims to have bred virus free
cucumbers for the South African market.
The way they explained it, it seemed inevitable that they had to make
hybrids otherwise the cucumber would run the risk to loose its virus
resistence again.

Hy Wytze,
MAS has currently been most successful with hybrid maize, but rice ,
which is not hybrid, has had successful applications. Wheat which is
self pollinated has has had less success than rice or maize. The
application of MAS to wild relatives of crops could be useful in
ensuring that those relatives are preserved.
Regarding organic certification, it seems hard to try to exclude
selections which have not been altered with synthetic transgenes but
have been selected using MAS. Efforts to exclude MAS from organic
certification would keep an army of lawyers employed for years!
Regrading plant patents, it is hard to see how the MAS patents would
differ in substance from the plant patents presently marketed.
Excluding all patents from "organic" certification should be debated,
however, I think that the issue is really separate from the meaning of
"organic". Hope this helps, sincerely, Joe Cummins

Turning to marker assisted selection (MAS) I agree that it is something
that organic agriculture can embrace because the crop genes are selected
not altered. Nevertheless,for some important QTL R.A.Fisher will prevail
leaving selection in the hands of patient breeders.

Hi Joe and everyone,
This is one of the rare occasions where I disagree with you. MAS leads
inevitbly to patented hybrids and is impossible in open pollinating
systems. I doubt that that is really helpful for the development of
organic agriculture.
