Subject:      Centres of origin

You need to distingusih between centre of origin and centre of diversity.
The two are not the same. Centre of origin is mostly unknown, and is often
not the current centre of diversity. To find genes of resistance you need
to study and select from samples in the current centre of diversity.
I hope this helps.
