Microsatellites as a powerful tool for identification of olive (Olea europaea L.) planting material in nurseries
Dunja Bandelj, Branka Javornik, 2007, original scientific article

Abstract: Microsatellites were applied to confirm the varietal identity of thirteen olive samples from a private nursery. Allelic profiles of samples were compared to genotyped reference varieties from three olive germplasm collections. Genotyping data of two microsatellite loci (ssrOeUA-DCA3 and ssrOeUA-DCA16) allowed discrimination of ten olive samples and the identification of six olive varieties (Koreneiki, Manaki, Tsounati, Kalamon, Ascolana Tenera, Picual). Mislabelling of two olive accessions (Manyanilla de Sevilla, Coratina) was observed and the lack of reference varieties Nostrana Bitontina and Miloelia hindered the identification of two accessions from the nursery. Accessions denominated as Miloelia and Gaiduroelia were of identical genotype. Different allelic profiles of the Frantoio reference variety were observed from two national olive germplasm collections. Microsatellites were found to be a valuable tool for varietal identity confirmation, in nurseries as well as for screening and managing olive germplasm collections.

Biennial bearing in olive (Olea europaea)
Shimon Lavee, 2007, review article

Abstract: Alternate bearing is a wide spread phenomenon in many fruit tree species and causes severe labor, marketing and thus economical problems. The domestic olive (Olea europaea) is genetically highly alternating in fruit production. The expression of alternate bearing in olives involves a wide range of changesin activation and repression of endogenous metabolic pathways. The degree of alternate bearing is highly dependent on the environmental conditions and might be very different in accordance with the climate in each growing region. The objective of this work was to present the main endogenous and environmental factors and their interactions that lead to alternate bearing and to review approaches with which alternate bearing is reduced.
