The group of variants analysed by MSAP.

The system used to identify individual variants in Table 1 is as follows: the cultivar abbreviation (MT = Müller Thurgau or R = Riesling) is followed by identification number of the cutting. Meaning of the suffixes: M-NI = maternal, non-infected plants; M-I = maternal, GFLV-infected plants; IV-NI = in vitro cultivated, non-infected plants; IV-I = in vitro cultivated, infected plants; TIV-NI = in vitro thermotherapy, non-infected plants; and TIV-HAI = in vitro thermotherapy, plants healed after GFLV infection. The notes “(1 year)” and “(8 weeks)” indicate the time interval elapsed since the transfer of plants from in vitro to non-sterile conditions.The group of variants analysed by MSAP.
