RESULTS AND DISCUSSION
Sterilisation procedure with DICA proved to be better
for all three genotypes. In the case of first genotype sterilised
with DICA, 38.2% of uninfected plants were obtained. The
sterilisation of the second genotype was less successful and
only 24.7% explants survived the sterilisation with DICA,
whereas the percentage of non vital explants was the highest,
reaching 49.5%. We can conclude that the concentration of
DICA was too high, or time of treatment was too long for
