Inbred Carrot Lines WAY274A and WAY274B


Irwin Goldman, Dwight "Nick" Breitbach

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in new carrot varieties.
OVERVIEWAccording to the USDA, Wisconsin farmers produced 73,610 tons of carrots in 2010.
THE INVENTIONUW-Madison researchers have developed a new line of carrots. 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.
  • Suitable for use in both fresh market and processing carrot hybrid cultivars
  • Long Nantes type with medium green foliage
  • Exhibits superior resistance to aster yellows
