Abstract:
Thirteen peach cultivars were used in experiments to produce somaclonal variants from
embryo culture.
In the first and second years of
the project, a total of 5,172 immature peach
embryos were excised and used in the protocol.
Initially, 45% of the immature embryos formed
friable callus in the first three weeks of culture.
One hundred plantlets (1987) 85 plantlets (1988)
formed in culture, however a large number
failed to develop further due to their inability to
form roots and some rooted plantlets were lost
during acclimation to greenhouse conditions.
The two year study produced 54 plantlets which
formed root systems.
The difficulty in obtaining
large numbers of plants from adapted cultivars
limits this in vitro technique for use in screening
programs for pathogen resistance in peach in
Ontario.
