BOSPOR

BOSPOR trees reach an age of 18 years, standing about 4.6 m tall with a crown diameter of 5.3 m. The crown is round, almost spherical, dense, and well-leafed, which ensures resistance to wind loads and increases yield. Fruits begin to ripen in the third year after planting; flowering occurs very late – at the end of April, and self-incompatibility allows them to be used as pollinators for other varieties.

The variety is characterized by a medium-early ripening period: under the conditions of the southern birch-maple climate, nuts are harvested at the end of August–beginning of September. Nuts are of medium size, round with a pointed tip, have a thin but strong shell and a brown smooth skin. The kernel is oval-pine-cone shaped, average mass 0.9 g, meets worldwide quality standards; kernel yield is 34.8%. Double kernels are almost absent.

Advantages of the BOSPOR variety include high yield (12.0–12.5 c/ha of dry nuts with a planting scheme of 6 × 6 m) and late flowering, which reduces the risk of fruit damage by early frosts. Due to good leafiness and resistance to wind loads, the trees are suitable for commercial cultivation in temperate climate conditions.
