Walnut culture has a good tradition and economic importance for Romania. Because most of the trees were seedling obtained by open pollination, it was necessary to start a breeding program. The research was done by University of Craiova and later also by Fruit Growing Research Station Vâlcea.

The breeding program developed into two directions:

  • selection of interesting varieties from walnut population existing in Romania (more then 470 0000 productive seedlings)., using a big genetic variability.
  • Obtaining a new variability by using controlled crosses between autochton genotypes and mainly “Ideal” variety (from Bostandik-Caucaz). “Ideal” has low vigor, is early bearing and has lateral bud fruitfulness.

Several local genotypes were selected: VL 4, VL54, VL57, VL102, characterized by high productivity, terminal bearing, good resistance to different diseases, big fruits (more then 11 g), uniformity good kernel shell ratio (more then 50%) and good quality of kernel.

From then 900 hybrids obtained by controlled crosses or by open pollination, 4 were selected. All of them have low vigor, early bearing, lateral bud fruitfulness, good productivity and good quality of nuts.

All selections are in the testing plots.
