Direct Organogenesis from Cotyledons in Cultivars of Citrus clementina Hort. Ex Tan243
of new hybrids reducing the propagation time in respect
to conventional methods. The obtained progeny, hybrid
and heterogeneous, can be multiplied through direct ad-
ventitious shoot organogenesis, thus obtaining more
identical individuals per seed who are more genetically
stable in comparison to plants regenerated via callus, in
which the presence of somaclonal variability is more
probable. The plantlets, that can be transferred success-
fully in vivo in the greenhouse, may be monitored and
evaluated for all new agronomic characteristics.
