Abstract
Differences in germination response at 35°C were found in tomato (Lycopersicon esculentum Mill.). Varieties with tolerance to germination at high temperature were characteristically cold-germinating types with the notable exception of the variety, Fireball. The ability to respond at high temperature was not found to be associated with earliness.
Abstract
‘Ohio 7663’ is an early-main season, machine-harvest tomato (Lycopersicon esculentum Mill.) with canning quality suitable for coreless whole-pack product. It was evaluated with good results, in the Northern Tomato Exchange Program (N.T.E.P.) trials in 1977 and 1978 and in other tests in Midwestern United States and Canada.
Abstract
‘Ohio 7681’ is an early-main season tomato (Lycopersicon esculentum Mill.) suitable for hand or machine harvest, released by the Ohio Agricultural Research and Development Center, September 1980. Canning quality favors juice and puree production.
Abstract
‘Ohio 7814’ is an early season tomato (Lycopersicon esculentum Mill.) adapted for machine harvest and bulk handling. Processing quality is especially suitable for the production of viscosity products and peeled, coreless, whole-canned tomatoes. It was released in November 1982 by the Ohio Agricultural Research and Development Center, The Ohio State University.
Abstract
‘Ohio 7870’ is an early-main season tomato (Lycopersicon esculentum Mill.) suitable for machine harvest with fruit qualities for the cannery that make it especially suitable for the production of juice, sauce, and coreless whole-canned tomato (whole-pack). It was released by the Ohio Agricultural Research and Development Center, June 1981.
Abstract
‘Ohio 832’ is an early, main-season, processing tomato (Lycopersicon esculentum Mill.) suitable for hand or machine harvest with fruit qualities that make it especially suitable for juice, sauce, and coreless whole-pack. ‘Ohio 832’ was released by Ohio State Univ., 3 Oct 1985. Several thousand acres of this tomato have been grown by the processing industry in the eastern and mid-western United States. It has been well received by growers and processors and use is increasing.
Abstract
‘Ohio 736’ is an early, well-adapted machine-harvest tomato (Lycopersicon esculentum Mill) with superior canning quality.
Abstract
Selected F3 and F4 lines of different origin were evaluated at high temperature (26° night and 35°C day) in the greenhouse along with several known heat-sensitive and heat-tolerant tomato (Lycopersicon esculentum Mill.) cultivars. A number of the selected lines had fruit set comparable to the tolerant cultivars Saladette, Ohio 7663, BL 6807, and Chico III. The expected greater fruit set of the tolerant cultivars vs. that of the sensitive cultivars was observed. High fruit set in this study was not associated with high seed number in the majority of tolerant cultivars evaluated.
Abstract
Ohio 11 and 12 greenhouse tomato Ly-copersicon esculentum Mill.) lines, resistant to Verticillium dahliae Kleb. Race 2 (Ve-Race 2) are pink, uniform-ripening, and large-fruited indeterminate types. Ohio 11 is also resistant to tobacco mosaic virus (Tm-22 ) and Fusarium oxysporum f. sp. radicisly Coper-sici (For). Ohio 12 has similar disease resistance, but is heterozygous resistant for Tm-22 . They have potential as a germplasm source of the Ve-Race 2 resistance and other desirable characteristics. They may be useful as inbreds for the development of commercial greenhouse tomato hybrids.
Abstract
Resistance to Fusarium crown and root rot (Fusarium oxysporum f. sp. radicis-lycopersici) in the tomato (Lycopersicon esculentum Mill.) was inherited as a monogenic dominant gene in a cross between the breeding lines 89-1 (resistant) and 1239A (susceptible).
