List of genotypes evaluated.

Boxplot of tomato ILs leaf water potential (LWP) in the two environmental conditions.
Environmental condition 1 = non-stressed plants, environmental condition 2 = plants subjected to drought stress. Circles indicate outliers in the dataset.
Fig 2.
Pearson’s correlation matrix of BLUP means for all traits showing significant genotypic effects.
Correlations were validated by the t-test at 0.05 significance level, and blank squares mean that the correlation was not significant (p > 0.05). BER = blossom-end rot, FW = fruit width, FWC = fruit water content, MFW = mean fruit weight, N_fruits = mean number of fruits per plant, TA = titratable acidity, Yield = total yield. Colors are related to the correlation values. The darker the red the closer to -1 and the daker the blue the closer to 1.
Fig 3.
Ranking of genotypes according to the ideotype for each trait and the percentage difference (increase or decrease) in relation to cv. M-82.
The genotypes closest to the ideotype are on the left. The colored gradient indicates the intensity of difference in relation to M-82: the deeper the blue and red colors, the more substantial the changes promoted by the S. pennnellii genome away from the ideotype. BER = blossom-end rot, FWC = fruit water content, MFW = mean fruit weight, N_fruits = mean number of fruits per plant, TA = titratable acidity, Yield = total yield.
