Assessment of nut quality of walnut varieties of Russian breeding in the conditions of Belarus

Abstract

The article presents the results of study of commercial qualities of five Russian breeding varieties of walnut. It was established that all the studied varieties, including the standard, are categorized to the group of large-fruited, with a fruit mass from 12.1 to 14.0 g. The highest percentage of kernel yield compared with the standard is in ‘Zarya Vostoka’ (51.2 %), ‘Mendeleevsky’ (46.2 %) and ‘Voron’ (46.6 %) varieties.

Morphological analysis and tasting assessment of walnut fruit of the studied varieties allowed us to identify three varieties (‘Zarya Vostoka’, ‘Voron’, ‘Mendeleevsky’) with economically valuable traits (fruit weight, kernel yield, recoverability, taste) that can be recommended as sources for breeding new varieties.
