Data from POP369 were collected in two successive years (2011 and 2012) while POP356 was analysed in 2011 only. Ranges are collected from genotypes scores averaged across the harvests. Units for trait studied are following: FD (scale), TSS (°Brix), Firmness (N: newton), PPO (change in A420/g/minute), AsA and polyphenols compounds (concentration). N.B.: comp_417.12 (1) and comp_417.12 (2) are unknown polyphenols compounds identified from LC-MS quantification analysis, represented by their molecular weight.
