Leccino
The mild, early-ripening blending partner of Tuscan oil — deliberately low in phenols — and, right now, the most agronomically important olive in Italy, because it is one of only two cultivars approved for replanting the Xylella-devastated groves of Salento.
In the grove
Leccino is widespread in Tuscany and has spread to Umbria, Puglia and new olive countries. It is strongly vigorous with a dense spreading canopy, comes into production early, and yields high and constant crops. It is totally self-sterile — Frantoio and Pendolino are the conventional pollinators — yet its own abundant, viable flowering makes it an excellent pollen donor in return.
Then there is Xylella fastidiosa. Screening under high inoculum pressure found Leccino showed the lowest bacterial colonisation and the lowest level of symptoms of the cultivars tested, and it is one of only two varieties permitted for olive reconversion in infected areas. That is resistance, not immunity: the same work notes Leccino still supports colonisation and can show symptoms.

Polyphenol figures are the ranges published for each variety, not measurements of any bottle in the library. A single oil's figure depends on when it was picked and how it was milled, and is shown on that oil's own page where the producer states one.
