| UNITED STATES DEPARTMENT OF AGRICULTURE AGRICULTURAL RESEARCH SERVICE and THE CALIFORNIA and FLORIDA AGRICULTURAL EXPERIMENT STATIONS RELEASE OF MARKET CARROT HYBRID, GOLDEN STATE The United States Department of Agriculture, Agricultural Research Service, in cooperation with the California and Florida Agricultural Experiment Stations, announce the release of GOLDEN STATE, pedigree (B3475 x B4367) x F524, a fresh-market hybrid carrot adapted for production in both organic and mineral soils where the market cultivars Gold Pak, Imperator 58 and Waltham Hicolor are grown. GOLDEN STATE has been evaluated for market quality in ten separate trials in California and Florida during three growing seasons, 1980 through 1982. Total yields have not been significantly different from Imperator 58, the most widely grown open-pollinated cultivar in California, but the marketable yield is generally higher and interior color and eating quality are superior and more uniform. In 1981 and 1982, winter-grown observation plots of GOLDEN STATE were displayed with commercial and experimental hybrid entries in trials at the University of California, Imperial Valley Field Station (IVFS) near El Centro, California. Quality evaluation by judges representing growers, shippers, seedsmen and breeders were on a numerical scale with a value of 1 for unacceptable 2 for poor, 3 for fair, 4 for good and 5 for excellent. The mean values for nine widely available commercial hybrids ranged from 1.3 to 2.8 in 1981 and from 2.2 to 2.9 in 1982. Following are the quality ratings: Mean Quality Ratings1/ Entry 1981 1982 GOLDEN STATE 3.4 3.3 Orlando Gold 3.4 2.9 Candy Pack 2.5 2.8 Imperator 58 2.0 2.2 9 commercial hybrids2/ 2.2 2.4 _________________________________________________________ 1/34 judges in 1981 and 30 judges in 1982. 2/Commercial hybrid entries were: Fanci Pak, Dominator, Pakmor, Chancellor, Dagger, Tancar, Hi Pak, Tahoe and Spartan Fancy. In similar trials in Florida GOLDEN STATE did not receive grades as high as Orlando Gold. Therefore it is recommended only for trial in the muck soils of central Florida. In California it should be subjected to large-scale trials under standard commercial cultural and handling practices.  |
| 2 The female parent of GOLDEN STATE produces unusually high yields of seed in combination with a variety of pollen parents. Following are seed yields produced in 1982 under five screen cages each with a different pollen parent: Pollen Isolation Seed yield Seed parent parent Hybrid no. gms/plant (B3640 x B4367) x B3640 F524 Orlando Gold 201 7.2 B3475 x B4367 F524 GOLDEN STATE 201 21.8 B3475 x B4367-11/ B8080 unnamed 205 25.2 B3640 x B30802/ B8080 " 205 10.6 B3640 x B30802/ B9253 " 207 12.4 B3475 x B43671/ B9253 " 207 23.2 B3475 x B43671/ B9692 " 209 23.6 (B3640 x B4367) x B36403/ B9692 " 209 12.5 B3640 x B30802/ B2327 " 213 4.0 B3475 x B43671/ B2377 " 213 14.4 ____________________________________________________________________________ 1/Female parent in GOLDEN STATE. 2/Female parent in Candy Pack. 3/Female parent in Orlando Gold. The average seed yield on (B3475 x B4367) with five different pollinators was 21.6 gms/plant while the seed parents of Candy Pack and Orlando Gold yielded an average of 9.3 gms/plant. Preliminary data from outdoor isolations indicate that the seed yield advantage exhibited by the GOLDEN STATE female under screen can be expected in seed production fields. This prospect of superior seed yields justifies the release of GOLDEN STAGE despite its failure to show any clear superiority over Orlando Gold in the root crop. The inbreds B4367M and F524 were released and distributed in April 1982 for use in the production of hybrid Orlando Gold. The sterile and maintainer lines of inbred B3475 were released in March 1983. Seedsmen interested in producing GOLDEN STATE already have the needed components. Seed of the sterile F1 parent was produced by Alf Christianson Seed Company under a standard increase contract in order to supply interested seedsmen with enough stock seed to undertake immediate production. Seedsmen who wish to produce GOLDEN STATE should request a pro-rata share of this stock seed. Those interested in testing the female (B3475 x B4367) in experimental combinations with other inbreds should request experimental samples for that purpose. Trial samples of GOLDEN STATE and small quantities of cage-grown breeders seed of lines B3475S, B3475M, B4367M and F524 can be secured by addressing requests to C. E. Peterson, USDA, ARS, Department of Horticulture, University of Wisconsin, Madison, WI 53706. Contracted pilot production of GOLDEN STATE scheduled for harvest in 1983 will be pro-rated by the Alf Christianson Seed Company at a reasonable wholesale price to seedsmen on orders received before September 1, 1983. In the event that any demand develops, this provision in the contract insures competing |
| 3 seedsmen a means of supplying their customers while initiating their own production. __________________________________________ _____________________________ Director Date California Agricultural Experiment Station __________________________________________ _____________________________ Director Date Florida Agricultural Experiment Station __________________________________________ _____________________________ Administrator Date Agricultural Research Service |
