* The assessment of the number of fruits per tree was carried out by grading them (regardless of the size of the fruit) as follows: 1—very small number of fruits per tree (under 6–8); 3—small number of fruits per tree (between 9–10 and 20–30); 5—average number of fruits per tree (between 31–40 and 60–70); 7—large number of fruits per tree (between 71–80 and 90–100); 9—very large number of fruits per tree (over 100). ** The assessment of the fruit size was performed by grading them as follows: 1—very small fruits (<50 g); 3—small fruits (50–85 g); 5—medium fruits (85–125 g); 7—large fruits (125–150 g); 9—very large fruits (over 150 g). The difference between any two half-sib families with a common tester followed by at least one common letter was not significant (Duncan’s MRT test; p < 0.05).
