Pat,
We use the Dellaporta microprep method from the Maize Handbook to extract
DNA from a single seedling leaf. Addition of RNase to the prep improves
PCR results.

>We need to isolate DNA (for PCR) from many thousands of maize plants.

>>Has anyone worked out a reliable, easy protocol from fresh tissue?
