Variété originaire des USA.

Origin. Selected originally in 1926 for resistance to Fusarium wilt out of a field of Indiana Baltimore badly infected with Fusarium wilt. Probably an accidental cross or a mutation. Maturity. A second early type, maturi1"1g along with Pritchard and Prairiana. Vine type. Intermediate in size, smaller than Indiana Baltimore; foliage finer cut and growth habit more decumbent. Blossoms set early and rather freely. No trouble has been experienced with excessive vine growth. Fruits. Red, smooth, deeply oblate, small scar, small core, shallow basin at stem end, solid and meaty with a thick rind. Seed cells vary from four to many. Early Baltimore is only a moderate seeder. Fruits are about the same size as Marglobe. Cracking varies with the season bJ.1t is mostly of the concentric type and shallow. The fruits retain most of the desirable characters of the Indiana Baltimore but mature a week or more earlier. Yields per acre (U. S. No.1 and U. S. No.2) 1930-Early Baltimore, 5.37 tons; Marglobe check, 2.38 tons. 1931-Early Baltimore, 7.82 tons; Greater Baltimore check, 2.18 tons. 1932-Early Baltimore, 9.39 tons; Marglobe check, 9.09 tons. 1934-Early Baltimore, 7.57 tons; Marglobe check, 4.30 tons. 1935-0n eroded brown silt loam, low in fertility Early Baltimore, 6.51 tons; Pritchard check, 6.45 tons. Duplicate test in 1935 on heavy black clay loam, high in fertility Early Baltimore, 7.17 tons; Pritchard, 6.62 tons. That Early Baltimore is particularly adapted to the midwestern conditions of extreme heat and dry weather is indicated by its superiority to the check varieties in the adverse drouth years of 1930, 1931 , and 1934. In normal years such as 1932 and 1935 the yield was equal to Pritchard, Marglobe, or Greater Baltimore. Use. Early Baltimore is excellent for market purposes and retains the high quality and quick, even ripening which make Greater Baltimore so popular for canning. The tests so far have shown that Early Baltimore may be grown on highly fertile soils without danger of excessive vine growth. On poorer soils its performance is satisfactory.
