Introdaction of blackberry (sort «Tornfree») into the culture

The  data  of  selection  of  optimal  variant  of  explants  defertilization (sort «Tornfree») are given. The field material is shown to be undergone of internal infection more then a hothours one. It is also educed that a bigger explants develops better though it is more difficult to sterilize it. The stable growing sterile culture has been got for further research.
