THE FLORIDA AND CALIFORNIA AGRICULTURAL EXPERIMENT STATIONS
RELEASE OF CARROT INBRED B3180
The United States Department of Agriculture, Agricultural Research Service and the California and Florida Agricultural Experiment Stations announce the release of a carrot inbred B3180 to provide germplasm for developing improved genotypes and producing proprietary hybrids. One experimental combination using B3180, [(B4367xB36402)xB3180] named Atlantis, has been announced because of its performance during two years of trials in Florida, California and Wisconsin.
In California trials of 122 entries judged by 15 experts in 1985, the ranking of B3180 hybrids was exceptional (see Table 1).
B3180 was derived from a cross made in 1982 between B8O8OxPI419042. PI419042 is a variety, Hong Ting Hsain, from Peoples Republic of China. B8080 was released by the USDA in 1983.
Probably greatest value of B3180 hybrids is the relative earliness of achieving marketable size. The inbred pollen parent B3180 also has potential value as a parent in the development of breeding stocks.
Seed produced under pilot production contract will be used to supply large requests. For breeding purposes and small trials, quality stock from cage isolation will be provided. Seed should be requested before May 1, 1987 and should be addressed to C.E. Peterson, USDA ARS Dept. of Horticulture University of Wisconsin, Madison WI 53706
