University Receives Donation of Ancient Olive Varieties

The seedlings, which were recently donated by Banco Santander, will be studied before given new life when they are planted at the Rabanales University campus.

The University of Córdoba in Spain has received a dona­tion of olive seedlings from uncat­a­logued ancient olive vari­eties.

They will be clas­si­fied and pre­served at the university’s Olive Germplasm Bank.

The seedlings, which were donated by Banco Santander, came from the vari­etal iden­ti­fi­ca­tion research work the University’s Higher Technical School of Agricultural Engineering and Forestry (ETSIAM) con­ducted on Banco Santander’s ancient olive tree col­lec­tion.

Located at the bank’s head­quar­ters in Boadilla del Monte in Madrid, this col­lec­tion is con­sid­ered the world’s most impor­tant pri­vate col­lec­tion of olive trees.

The agree­ment between Banco Santander and the university’s UCOLIVO group has so far enabled the clas­si­fi­ca­tion of more than 200 cen­te­nary and mil­lenary olive trees in the col­lec­tion.


Researchers applied mor­pho­log­i­cal and mol­e­c­u­lar mark­ers for the analy­sis of the trees, the major­ity of which were spec­i­mens of known vari­eties, includ­ing Farga and Lechín de Granada.

The research revealed three rel­e­vant major find­ings. They iden­ti­fied nine known olive vari­eties that are prob­a­bly among the old­est.

They also detected a pat­tern of high fre­quency graft­ing done with wild olive trees in ancient times.

Finally, they dis­cov­ered the exis­tence of mil­lenary vari­eties that had not yet been cat­a­logued, but whose resis­tance over time sug­gests they are excel­lent spec­i­mens to study, specif­i­cally for the traits that affect their longevity. This could be instru­men­tal for the improve­ment and sus­tain­abil­ity of olive crops.

The university’s UCOLIVO group has been work­ing on the iden­ti­fi­ca­tion of Banco Santander’s olive vari­ety col­lec­tion since 2013.

Banco Santander’s olive tree col­lec­tion started in the early 2000s with the bank’s for­mer pres­i­dent, Emilio Botín. He began a search for very high qual­ity olive trees to be planted at the bank’s new head­quar­ters and con­sid­ered nature as a vehi­cle to cre­ate a work­ing envi­ron­ment that made employ­ees more com­fort­able and more pro­duc­tive.

Experts helped the now deceased Botín to assem­ble the col­lec­tion of olive trees, which orig­i­nally came from Spain, Portugal, Italy and North Africa. Botín began buy­ing cen­te­nary olive trees for the col­lec­tion as a means to pro­tect them from being cut.

The col­lec­tion extends over more than 350 acres and has some 1,500 trees, one-third of which are mon­u­men­tal and sin­gu­lar, includ­ing mil­lenary olive trees. A team of pro­fes­sion­als over­sees and mon­i­tors the trees, con­duct­ing strict peri­od­i­cal con­trols of their devel­op­ment and phy­tosan­i­tary con­di­tion.

The trees that grow from the donated seedlings will be planted at the Rabanales University cam­pus where more than half of the world’s 1,200 olive vari­eties are pre­served.

Prior to this exer­cise con­ducted by UCOLIVO, Banco Santander had already worked with Spain’s Higher Council for Scientific Research (CSIC) to com­plete the world’s first full DNA sequenc­ing of an olive tree, a mil­lenary tree, a copy of which was also donated by the bank to the University of Córdoba for its incor­po­ra­tion into the Olive Germplasm Bank.
