Kernel oil content and oil composition in walnut (Juglans regia L.) accessions from north-eastern Italy.

The wide variation in fatty acid content and composition allows superior accessions to be selected for diffusion among growers. A suitable strategy would be to make a selection against PUFA content rather than just for high oleic acid. In addition, the selected high oleic accessions, before being utilized per se or as donor parents in breeding programs, have to demonstrate they are not adversely affected by the environment. © 2017 Society of Chemical Industry.
