Abstract: Disclosed herein are methods of producing substantially pathogen-free plants of the genus Cannabis and pathogen-free plants and clones produced therefrom. One embodiment of the method comprises pretreating a progenitor plant of the genus Cannabis, surface sterilizing a shoot segment of the pretreated plant with a bleach solution, excising a meristematic tip of the shoot segment, and transferring the meristematic tip into a culturing plate comprising a supplemented Murashige and Skoog culture medium for further culturing. The supplemented Murashige and Skoog culture medium can comprise benzyladenine, naphthaleneacetic acid, gibberellic acid, or a combination thereof.

Abstract: Disclosed herein are methods of producing substantially pathogen-free plants of the genus Cannabis and pathogen-free plants and clones produced therefrom. One embodiment of the method comprises heating a progenitor plant of the genus Cannabis within a heating chamber resulting in a heat-treated plant, surface sterilizing a shoot segment of the heat-treated plant with a bleach solution, excising a meristematic tip of the shoot segment, and transferring the meristematic tip into a culturing plate comprising a supplemented Murashige and Skoog culture medium for further culturing. The supplemented Murashige and Skoog culture medium can comprise benzyladenine, naphthaleneacetic acid, gibberellic acid, or a combination thereof.
