摘要

Hazelnuts (Corylus avellana) are considered the most important nut crop due to their high nutritional and economic value. This research examines the morphological and technical characteristics of the seven hazelnut varieties in Georgia, including Anakliuri, Gulshishvela, Dedophlis Thithi, Shveliskura, Chkhikvistava, Khachapura, and Kharistvala. The harvested 2–3 kg of mature fruits underwent a standardized drying process and were collected in September 2022. The assessment focused on morphological characteristics, such as color, shape, apex, basal shapes, and indumentum of fruits, and biometric determination of kernels, including shape, length, width, and thickness. The technical characteristics covered fruit weight, kernel-to-shell ratio, and total yield. The findings revealed a range of fruit shapes, including oblong-cylindrical, round, round-oval, and round-flat, with variation in the fruit dimensions. The kernel-to-shell ratio was between 0.9 and 2.27 g. Gulshishvela cultivar exhibits the highest proportion of kernel-to-shell ratio of 52.8% compared to other varieties. Consequently, this makes Gulshishvela suitable for processing and commercial use, where kernel yield is an important consideration. This study leverages important perceptions as morphological features of various Georgian hazelnuts, which can inform cultivation practices and increase the economic feasibility of the different varieties in both local and international markets.
