Data are presented on the oil content and composition in the seeds of 1156 native jojoba plants harvested individually from inland and coastal areas of California and Arizona in the U.S. and from Sonora and Baja California in Mexico. The mean oil content of these samples was 53.2%; 34.2% of the samples exceeded 53%. The mean single seed weight was 0.56 g. A significant correlation between single seed weight and oil content was found but there was no correlation between oil content of the seed and seed yield per plant. Analysis of the oil for fatty acids and fatty alcohols showed very little variability among samples. This compositional uniformity is a major asset in terms of industrial application of this oil. Half the seeds studied in 144 samples had a mean oil content of 49.5% and mean single seed weight of 0.39 g. Simple correlations between fatty acids and oil content were similar to those reported earlier.
