Table S1. Accessions of the lettuce diversity set, including cultivars and wild relatives, representative of the primary lettuce gene pool readily accessible by lettuce breeders.

Table S2. Restricted estimates maximum likelihood (REML) analyses of postharvest (a) pinking and (b) browning traits of minimally processed lettuce diversity set accessions stored in semi-permeable packaging over 13 days at 5 C in the dark.

Table S3. Mean values for postharvest pinking and browning traits of minimally processed lettuce diversity set accessions stored in semi-permeable packaging over 3 days at 5 °C in the dark.

ijfs12030-sup-0002-figS1.tifimage/tif364KFigure S1. Correlation heatmap based on Pearson's correlation coefficient for measurements of postharvest discoloration traits of minimally processed lettuce averaged over the accessions of the diversity set stored in semi-permeable packaging over 13 days at 5 °C in the dark (n = 28). White for negative correlations, grey for zero and black for positive. (a–e) Mean browning intensity on days 1, 3, 6, 9, 13, across days; (g–l) mean extent of browning on days 1, 3, 6, 9, 13, across days; (m–r) mean pinking intensity on days 1, 3, 6, 9, 13, across days; (s–x) mean extent of pinking on days 1, 3, 6, 9, 13, across days.
