Variety and typology of hazelnut plants

Our nursery is specialized in the cultivation of the “Tonda Gentile” variety and related clones.

  • Tonda Gentile delle Langhe “: From the last year, we started to multiplicate two clones (“unito MT5” – “unito AD17”) provided from DIFASA (University of Turin, in collaboration with CReSO) that positively increase both quality and productivity of the original variety. Actually, this material is not available yet.
  • Tonda Gentile Romana” This variety, mostly prevailing near Viterbo, has a good productivity. It rips about 20 days later the “Tonda Gentile delle Langhe” and it is recommended for the same type of soils. This variety well pollinate the “Tonda Gentile delle Langhe”.
  • Pollinators: For this pollinators, there’s a limited availability:

Wild nut
“Tonda Gentile romana”

Blooming period:
TONDA GENTILE: female blooming from January to February (sometimes, the blooming could delay -till
March);
DARIA: premature male blooming from January to February;
119: premature male blooming from January to February;
G1: medium-premature male blooming in February;
Romana: medium-tardive male blooming from February to March.

The wild nut has a blooming period really long: from February till the end of March, on the basis of the existing plant life. In nature, the “Tonda Gentile” is pollinated from the wild nut, naturally grown from seeds. Each plant, passes on the DNA of the mother plant. Consequently, the pollination is really long, due to different plant lives which have not a conform period of male blooming.

Using the wild nut as a pollinator, the production isn’t going to be contaminated by different variety. A good expedient could be, where possible, to arrange the wild plants at the edge of the hazelnut plantation, leeward, considering that the pollination happens in January, February, and March when the wind is directed in north/north-west.
