Common walnut Kodrene

A vigorous variety. Requires fertile, deep, light soils. Highly resistant to frost, tolerates low temperatures down to -32°C and even -35°C without significant damage. Also resistant to anthracnose and pests. Bud break occurs 4-5 days later compared to medium-bud-break varieties. Female flower bloom occurs at the end of April to early May. Flowering type is protogynous, with a difference of 1-4 days. Female flowers appear in buds that are not yet fully opened, which to some extent protects them from spring frosts.

Fruit production — abundant and regular, fruiting type is terminal — intermediate, i.e., from terminal buds and 1-2-3 lateral buds. Production is relatively uniform. Nuts are large, shell seams are strongly fused, poorly expressed, surface relatively smooth, shell relatively thin, easily splits open, kernel is removed whole or in halves, has an attractive appearance. Variety was released in 2005.

Tree habit

A vigorous tree, at 30 years old reaches 10 m height, has an imposing appearance, foliage abundant, dark green, leaves large, broadly elliptical, trunk straight, cylindrical.

Crown — spherical, spreading, medium density.

Scaffold branches — thick, strong, well consolidated on the trunk, large branching angle, bark gray color.

One-year shoots — thick, healthy, 30-50 cm long, brownish-yellow, with longitudinal lenticels.

Male inflorescences — thick, 10-12 cm long, numerous.

Fruit

Nuts large, length — 39.3 mm, width — 33.1 mm, thickness — 37.7 mm, mass of one nut — 13.3 ± 0.85 g, uniformity CV=14%.

Shape — broadly oval, with slightly protruding pistil tip, base rounded.

Endocarp — relatively thin, 1.4 mm thick, easily splits open, shell seams strongly fused, poorly expressed, peduncular opening medium size, well covered by conducting bundles, brownish-white color.
