The hybrid nut, in this case a cross between Juglans nigra and Juglans regia, comes from a plantation in France and is called NG23 Lataule.
In a cultivation trial with various French hybrid nuts, NG 23 performed best.
The origins were testedMJ 209, NG 23 and G 38
The NG 23 showed the lowest mortality and the best growth performance of all.
The hybrid nut is due to its strong growth performance(so-called luxuriant growth very interesting for forestry use.
It provides a very valuable wood that is one of the most expensive that can be found in our local forests.
The hybrid nuts can withstand winter temperatures of up to approx. 30C without damage. The sensitivity to late frost is lower than that of the black walnut.s.
The risk of fungal and bacterial attack is lower than with walnuts.
A hybrid nut at the age of 90 can easily reach a BHD of 100 cm and more, depending on the location, it then has a height of around 35 meters and an estimated trunk wood volume of more than 9 m3.
At a price of up to 8,000 per cubic meter, this makes a sum of around 70,000 per tree..
