Left, single-fruit weights of MbTMV-MT F 1 ( n = 40), Funtelle F 1 ( n = 34) and four tetraploid MbTMV-MT-Funtelle MiMe plants (1, n = 41; 2, n = 53; 3, n = 46; 5, n = 52). Right, single-fruit weights of MbTMV-MT F 1 ( n = 40), Maxeza F 1 ( n = 17) and 12 tetraploid MbTMV-MT-Maxeza MiMe plants (1, n = 27; 2, n = 31; 3, n = 36; 4, n = 18; 5, n = 35; 6, n = 28; 8, n = 11; 9, n = 23; 10, n = 15; 11, n = 33; 12, n = 30; 13, n = 25). The same MbTMV-MT F 1 data are used twice in this panel for comparison. We used ordinary one-way ANOVA followed by Šídák’s multiple-comparison test: P < 0.05, ‘NS’ (not significant); * P < 0.05; ** P < 0.01; *** P < 0.001; **** P < 0.0001.
