the regeneration of microspore-derived embryos and DH plants,
very important for future potential applications in breeding programmes
of this fruit tree of economic interest.
Many are the factors affecting the success of the pollen embryogenesis
(microspore developmental stage, anther or floral bud
pre-treatments, medium composition, culture conditions, etc.) and,
for this reason, a deeper knowledge and understanding of this
process and how the factors drive morphogenic competence and
development, will enable the effective deployment of gametic
embryogenesis and haploid technology in the improvement of apricot
and generally of fruit trees. Further efforts are necessary to
obtain regeneration of microspore-derived embryos and plantlets.
