Ohio 981670 (Ohio 9816) and Ohio 987034 (Ohio 9834); Solanum lycopersicum (Lycopersicon esculentum); Tomato germplasm (PV003-06)


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. Foliage cover is adequate for ensuring good fruit quality at maturity. The average machine harvest yield of Ohio 9816 was 43.8 TIA over three years of testing. The average machine harvest yield of Ohio 9834 was 37.9 TIA over three years of testing. 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, and are attached by a jointless pedicel. The sampled raw and processed product is characterized by soluble solids content, tritatable acidity, and vitamin C content that is comparable to industry standards in the midwest and eastern U.S. The color and uniformity of color for fruit for both lines is comparable to mid-season varieties currently in use in the mid-west and eastern U.S. making
these lines appropriate for the development of hybrids for peeled, whole-canned, and diced
tomato products.

Disease resistance

Both lines have partial resistance to race Tl of bacterial spot [Xanthomonas campestris pv. vesicatoria], resistance to race 1 (J) o Fusarium wilt [Fusarium oxysporum Schlechtend. F. sp. lycopersisci (Sacc.) Snyder and Hansen], and resistance to race 1 (ve) ofverticillium wilt [verticillium dahliae Kleb]. The source of partial resistance to bacterial spot is Hawaii 7998 and genetic studies have indicated that both lines carry an introgression on chromosome five.
