Fruits of this variety are characterized by a very large size, measuring approximately 54 x 60 mm, and a thin shell that allows the kernel to be extracted by hand. The average kernel weight is 10 g with a kernel percentage of about 40%. The tree is vigorous with a widely spreading crown, requiring the presence of pollinators due to its protogynous flowering type.
Fruit ripening occurs in the second half of October. The variety possesses high wood winter hardiness and good resistance to bacterial blight. Yield is estimated as moderately high, where the number of fruits is compensated by their significant mass.
The variety is used in breeding programs to create hybrid populations aimed at studying the composition of fatty acids and tocopherols.
