This study was conducted in the two-year period of 2006 and 2007 to determine the parameters of growth and reproduction of preliminary propagation of pre basic plants from two vigorously developing introduced raspberry cultivars Tulameen and Meeker at four terms of vegetation. They were grown in special conditions, in cultivation facilities with a close-meshed net and overlaid with a polyrethane coating. These protection measures were intended to protect the propagate plants from carriers of viral diseases. Estimation of propagation potential of the cultivars was made. Our standard cultivar Balgarski Rubin was used as a control.
