Phenotyping of variant pairs upon open-pollination. Members of the same pair (or triplet) are depicted with the same color. For each accession, a mean value was calculated from different bunches, seasons and locations. Bars correspond to standard errors. Asterisks indicate significant (P < 0.05) differences between seeded and seedless variant pairs, as established by one or more test(s) among T-Student test (or Welch test in the case of unequal variances), Mann-Whitney test, and Kolmogorov-Smirnov test. Different letters indicate significant differences in the whole set of accessions (Kruskal-Wallis test followed by Dunn’s post hoc test with Bonferroni correction for multiple tests, P < 0.05). In (a) berries with apparently normal seeds were considered as seeded, whereas berries containing only rudimental seeds, seed traces or unfertilized ovules were classified as seedless. In (e) Corinthe Noir fruit set rate measured at harvest (34%) was lower than that evaluated at fruit set stage (68%), since most berries were dried and part of them had already fallen.
