Over two centuries ago Jonathan Swift wrote “necessity is the mother of invention.” Because the late Professor Emery Myers Emmert could not afford an expensive glass greenhouse, he invented the plastic greenhouse in 1948.

These differences suggest the feasibility of breeding for “wet feet” resistance in peach rootstocks.
