Interpretive Summary: A two-year evaluation of 53 hazelnut accessions for yield and nut characteristics identified varieties (as Lewis, Ennis and other) that may be cultivated in San Joaquin Valley, California. The study also contributed to the characterization of the USDA-ARS hazelnut collection.
Technical Abstract: Worldwide, hazelnuts Corylus L. (Betulaceae) are one of the most economically important nut crops cultivated in the northern hemisphere. With its tasty nuts valued on the global market, emerging discovery of the plant pharmaceutical properties, and its role in sustainable agroecosystems, there is a quest to find and develop cultivars suitable for new growing areas. In a two-year study, 53 hazelnut accessions from the Corvallis germplasm collection, were evaluated for nut yield, kernel percent, weight, and shape, in San Joaquin Valley (SJV), California. The best traits were observed for ‘Lewis’ (PI 617210) and ‘Ennis’ (PI 557045); however, a few other accessions showed characteristics supporting cultivation in the SJV growing conditions. These findings might serve as a guidance for cultivar selection for farming in that region. The evaluation also contributed to the characterization of the USDA-ARS National Plant Germplasm System collection of Corylus.
