Développement de la variété "Century"

Obtention W. A. Huelsen probable en 1925

Variété originaire des USA.

Origin. One of the earliest wilt-resistant types produced by systematic breeding. Selected about 1913 by C. E. Durst, formerly of the Illinois Station, for resistance; by 1917 seed of the variety was produced under the name "Century" and distributed to growers in Union county, Illinois. "Century" was a selection out of a variety called " ew Century" and had a high degree of wilt resistance. It did not become popular in Union county, possibly because the growers preferred a pink tomato. In 1925 the author found a few seeds of "Century" which, when grown in central Illinois, had tremendous vines and very late maturity. Continued selection has reduced the vine size and increased earliness so that Illinois Pride is now quite different from "Century." Vine type. Large vines of the Stone type, heavy foliage, blossoms rather late. The vines hold their leaves well. Excessive vine growth must be guarded against in the same manner as in other late varieties. The plants are unusually resistant to Fusarium wilt. Fruits. Red, smooth, very deeply oblate, round or nearly so ill cross-section. Rinds are thick, cell arrangement varies, and cell number varies from four to very many. The cores are small and 't~there is a large, meaty central region which makes the fruits very attractive when cut. The blossom scar is medium size and the basin at stem end is shallow. Illinois Pride is a moderate seeder. In tests for solidity and shipping ability it was considerably superior to Marglobe. Yields per acre (U. S. No.1 and U. S. No.2)
1930-IIIinois Pride, 4.49 tons; Marglobe check, 3.32 tons. 1931-IIIinois Pride, 4.40 tons; Greater Baltimore check, 2.60 tons. 1932-IIIinois Pride, 9.76 tons; 1ifarglobe check, 8.89 tons. 1934-IIIinois Pride, 3.86 tons; Marglobe check, 3.74 tons. 1935-IIIinois Pride, 5.43 tons; Marglobe check, 5.31 tons. Illinois Pride has given small but consistent increases over :Marglobe from year to year. It tends to have a larger fruit than Marglobe and does not crack so badly. Use. Illinois Pride is a good market tomato and a good shipper. It has excellent canning qualities, according to actual tests, and is now being used extensively for that purpose by one canner. On highly fertile prairie soils it should be grown with caution because of the danger of excessive vine growth. Various trials in southern and in northern Illinois have given very satisfactory results.
