Somaclonal variation in olive (Olea europaea L.) plants regenerated via somatic embryogenesis: Influence of genotype and culture age on genetic stability

Embryogenic culture-induced olives from the same cotyledon maintained in in vitro conditions for 3 years showed genetic instability due to long term maintenance.

“Embryogenic culture-induced olives from the same cotyledon maintained in in vitro conditions for 3 years showed genetic instability due to the long term maintenance [33].”

Phenotypical characteristics are controlled by several genes.

“Similarly, no correlation between genetically somaclonal varied plants with phenotypic changes was found in this study as phenotypical characteristics are controlled by several genes [33].”

Stem cutting in vitro culture in olive was stable.

“Since stem cutting in vitro culture in olive was stable, therefore 97% resemblance between ˈAminˈ MIS and ˈArbequinaˈ MIS proved high similarity between these cultivars [20, 23, 33].”

This is the first study that compared genetic stability and ploidy level fidelity in olive plantlets originated from MIS and CIS.

“Studies on genetic stability in somaclonal varied olives are scarce [33] and so, this is the first study that compared genetic stability and ploidy level fidelity in olive plantlets originated from MIS and CIS.”

The 97% resemblance between ˈAminˈ MIS and ˈArbequinaˈ MIS proved high similarity between these cultivars.
