SELECTION OF TONDA ROMANA AND TONDA DI GIFFONI CROSS POLLINATED HAZELNUT SEEDLINGS

A. Tombesi, P. Preziosi, M. Boco
In 1983, 4000 seedlings of Tonda Romana and Tonda di Giffoni, derived from cross pollination were planted at a 3.5xlm in spacing. On the seedlings selected after an initial screening carried out in the 8th year, 8 selections were evaluated for agronomic and technological traits.

Their main characteristics, (with pellicle removal, scoring from 0 to 10) are:

  • F4-32: growth habit, moderate upright; kernel percent, 42.60%; round index, 0.932; pellicle removal, 10.
  • F6-P200: growth habit, upright; kernel percent, 48.89%; round index, 0.995; pellicle removal, 9.
  • F25-P29: growth habit, upright; kernel percent, 67.20%; round index, 0.995; pellicle removal, 6.
  • F13-P9: growth habit, upright; kernel percent, 57.84%; round index, 0.840; pellicle removal, 10.
  • F21-P12: growth habit, upright; kernel percent, 54.08%; round index, 1.003; pellicle removal, 9.
  • F19-P29: growth habit, upright; kernel percent, 51.55%; round index, 0.894; pellicle removal, 9.
  • F15-P5: growth habit, very upright; kernel percent, 48%; round index, 0.826; pellicle removal, 10.
  • F25-P33: growth habit, spreading; kernel percent, 44.21%; round index, 0.820; pellicle removal, 10.

Trials are in progress to assess orchard performance and to cross the best seedlings.
