I assume that the backcross is marker-assisted for SNPs in the blight resistance locus. If that is true it amounts to the same thing you are proposing. Sounds

I assume that the backcross is marker-assisted for SNPs in the blight resistance locus. If that is true it amounts to the same thing you are proposing. Sounds just like making a speed-congenic mouse. Are they not selecting with markers at all?

They seem to be selecting with their eyeballs. They're jabbing trees with chestnut blight and seeing which ones succumb. Hence a petri dish for pathogen selection. IE, insane and reckless.

  Sounds like they're actively trying to evolve a blight that infects Asian chestnuts as well.

    It’s the dumbest Jurassic Park level scientific laziness I’ve heard all century.
