  1. Correlation of mean trait values measured in the glasshouse trial, with shelf life data taken from previous investigations on the same RIL subset, taken from Zhang et al. (ref. 32). ***P < 0.001; **P < 0.01 and *P < 0.05 levels. AO, antioxidant potential; CHL, total chlorophyll content; CAR, total carotenoid content. Correlations for all traits measured can be seen in Supplementary Table S3.
