I have a PDF of DJ’s book. Section 1 is cultivation, section 2 is breeding. It’s pretty good. I’ve got a few books about general plant breeding, and some heavy science stuff about next-gen breeding, new pheno/genotyping methods.
Some of them are too big to post here. If anyone’s interested I can zip them up, dump them on Dropbox and post a link.
Guess I could post the book.
