‘Ohio OX52’ Hybrid Processing Tomato Francis, D . M . and Berry, S . Z . Ohio Agricultural Research and Development Center, Horticulture and Crop Science, 1680 Madison Ave . , Wooster, OH 44691 USA ‘Ohio OX52’ is an early - season processing tomato ( Lycopersicon esculentum Mill . ) hybrid adapted to high population transplant culture, machine harvest, and bulk handling under humid growing environments .   It is suited for the production of peeled, whole - canned, and diced tomato products . Origin:   ‘Ohio OX52’ is the F1 hybrid resulting from the cross of the inbred line O87160 and Ohio 7814 (Berry et al . 1983) .   The line O87160 is an F6 selection from the cross of Ohio breeding lines B2905 - 1 and B2634 - 1; B2905 - 1 was derived from the cross ‘Ohio 7870’ X ‘K1483 - 3’ .   B2634 - 1 was derived from the cross Heinz 2653 and Heinz 722 .   O87160 is derived from the same F 3 as O88119 (Berry et al . , 1995) ______ Ohio 7870 | ______ B2905 - 1 (F5) ___ | ______ | | | O87160 | | ______ K1483 - 3 | (F6) | ______ Heinz 2653 | | | | | ______ B2634 - 1 (F5) ___ | ‘Ohio OX52’ _ | | | | ______ Heinz 722 | | | | ______ Ohio 7814 Fig . 1 .   Pedigree of ‘Ohio OX52’ Description:   ‘Ohio OX52’ vines are medium in size, semi - prostrate, and determinate (sp) .   Foliage cover is adequate for ensuring good fruit quality and at maturity the vines cover the row area uniformly .   The average maturity from transplant to harvest of ‘Ohio OX52’ is 97 . 1 days over four years of field testing, and is comparable in maturity to the early season standard, ‘Ohio 7983’ (Berry et al . 1992) . The average machine harvest yield of ‘Ohio OX52’ was 33 . 2 T/A over four years of testing (Table 1), outperforming the major early season varieties ‘Ohio OX 88’ and ‘Ohio 7983’ (though differences were not always significant) . Yields of ‘Ohio OX52’ were comparable to the main - season variety ‘Ohio OX38’ and somewhat less than the major main - season variety Peto 696 . Fruit of ‘Ohio OX52’ average 2 . 1 oz with two to three locules .   The shape is ovate .   Fruit have a small stem scar and core, are uniform ripening (u), and are attached by a jointless pedicel (j2) .   The color and uniformity of color (expressed as a color difference) for fruit from ‘Ohio OX52’ are comparable to other varieties of the same maturity and superior to the main - season varieties OX38 and Peto 696 (Table 2) .
