Images of dates. a A subset of 14 mature dates representing the 14 countries sampled in this study and reflecting diversity in phenotype. b Immature dates from two date samples 93-BSDN-MA and 91-BLZ-MA from the second sample collection. Each fruit is labeled with an ID featuring a letter that indicates its rank by extent of ripening relative to the remaining fruits within the sample (refer to methods). c Summary of the date metabolomics datasets measured by Metabolon: 10 fruits from the first sample collection were measured again with fruits from the second sample collection to account for batch measurement effect. All fruits from the first collection were considered mature (shown in green) whilst some fruits from the second sample collection displayed a phenotype indicative of ongoing ripening (refer to methods) and were therefore considered immature (shown in yellow). DS1 has the suffix ‘-bolon’ attached to distinguish it from the MetaSysX measurement of the same fruits from the first sample collection. The second sample collection was only measured by Metabolon
