Walnut (Juglans regia L) is one of the most important tree species in Uzbekistan. Natural walnuts have a valuable gene pool, among which there are many forms with different bioecological properties. In particular, biodiversity in terms of kernel quality is highly variable within the species. This article provides information on the analysis of quality indicators of walnut kernels in natural and local nuts. Among the indicators of kernel quality in the selected forms, the yield of walnut kernels was of high importance as the main indicator, and in the selected forms this indicator was 38.2-63.3. According to international indicators, Parkent-2, Boysun-1 and Humson-5 forms are recommended for wide use, given that the form with a yield rate of more than 50% is promising.
