1Francis, D.M. and S. Miller. Ohio 9834 and Ohio 9816:  processing tomato breeding lines with partial resistance to race T1 of bacterial spot. 1E-mail francis.77@osu.edu Pedigree of Ohio 9816 and Ohio 9834 ___ Hawaii 7998    | ____    Ohio 88119 X F1 | |   _____| |___ Ohio 88119 | | 9816          _______    | |____   Ohio 88119 | 9834         _______ | |__________  Ohio 88119 Characteristics Fruit:  Fruit of Ohio 9816 and Ohio 9834 average 2.0 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). Plant:  The vines of Ohio 9834 are small to medium in size and the vines of Ohio 9816 are medium to large in size.  Vines of both lines are prostrate and determinate (sp).    Disease resistance. Both lines have partial resistance to race T1 of bacterial spot [Xanthomonas campestris pv. vesicatoria], resistance to race 1 (I) of Fusarium], and resistance to race 1 (Ve) of verticillium wilt. The source of partial resistance to bacterial spot is Hawaii 7998 and genetic studies indicate that both lines carry an introgression on chromosome 5. Utility.  Ohio 9834 and Ohio 9816 are mid season lines adapted to high population transplant culture, machine harvest, and bulk handling under humid growing environments.  They are suitable parental lines for the development of hybrids used in the production of peeled, whole-canned, and diced tomato products.  Both lines have been tested in plot trials the mid-western U.S.  Hybrids using these lines have performed well in plot trials and in commercial scale strip trials in the mid- western and eastern U.S., in Ontario, Canada, and in Victoria, Australia.
