Inbred Carrot Lines W281C

Inbred carrot line W281C is a long Nantes type with excellent color and canned product quality. It was derived from the cross [(W267 x W259) x (W259 x W267)]. W267 is an unreleased inbred line, while W259 is an inbred line previously released by the University of Wisconsin Carrot Breeding Program that possesses exceptional color and flavor. Based on pedigree, W281C is very similar to W259, but has normal cytoplasm and carries alleles for fertility at the nuclear restorer locus. In addition, the foliage of W281C is slightly superior to Lucky B, a processing carrot hybrid produced from inbred lines previously released by the Carrot Breeding Program.

BENEFITS:

Exceptional color and flavor

Superior foliage to Lucky B

Suitable for use in both fresh market and processing carrot hybrid cultivars

Inbred Carrot Lines W280A and W280B

Inbred carrot line W280 is a long Danvers type with a tapered root and light green foliage. W280 was derived from a cross between the unreleased inbred lines, W261 and W262. W280A is a green petaloid sterile and W280B is the maintainer genotype.

BENEFITS:

Long Danvers type with a tapered root and light green foliage

Suitable for use in both fresh market and processing carrot hybrid cultivars

Inbred Carrot Lines W279A and W279B

W279A (sterile) and W279B (maintainer) represent long Chantenay type, inbred carrot lines with medium green foliage. W279 was derived from a cross between W267, an unreleased, inbred line, and W233, an inbred line previously released by the University of Wisconsin Carrot Breeding Program.

BENEFITS:

Long Chantenay type with medium green foliage

Suitable for use in both fresh market and processing carrot hybrid cultivars

Inbred Carrot Lines WAY274A and WAY274B

WAY274A (green petaloid sterile) and WAY274B (maintainer) are inbred, carrot lines possessing superior resistance to the plant disease aster yellows, which is caused by a mycoplasma-like organism and spread by the aster leafhopper, Macrosteles fascifrons stal. During three years of field trials, less than 8% of WAY274 plants per plot were infected with aster yellows, compared with an average of 24% among six commercial cultivars. WAY274 is a long Nantes type with medium green foliage. The line was derived from a cross between Scarlet Nantes and the unreleased population Aster Yellows Synthetic 1983, followed by a cross with the unreleased, inbred line W262.

BENEFITS:

Long Nantes type with medium green foliage

Exhibits superior resistance to aster yellows

Suitable for use in both fresh market and processing carrot hybrid cultivars

Carrot (W266E) Carrying a Reduced Pigment Gene and Its Use

Alpha-tocopherol (vitamin E) cannot be synthesized by the body and is often lacking in the U.S. diet. Vitamin E can be obtained from foods such as apples, nuts, and certain oils; however, its presence has not been recorded in carrots.  This invention provides a carrot plant that synthesizes alpha-tocopherol in its root. The ability of this carrot variety to synthesize vitamin E is linked to its being homozygous for the recessive reduced pigment gene (rp). Carrots homozygous for the reduced pigment gene generally have a total alpha-tocopherol content between 0.01 mg and 0.40 mg per 100 grams of fresh weight of carrot root. These carrots also have white roots and contain reduced levels of carotene.

BENEFITS:

Reduced pigment gene confers increased alpha-tocopherol levels in different genetic backgrounds

Could provide needed vitamin E to U.S. diet

Novelty carrot – white root instead of orange

New addition to cut-and-peel baby carrot market
