Inbred Carrot Lines May Resist Root-Knot Pest
WARF: P120304US01
Inventors: Irwin Goldman
The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in carrot varieties having potential resistance to Northern root-knot nematode.
Overview
According to the USDA, Wisconsin farmers produced 73,610 tons of carrots in 2010. Unfortunately, carrot is highly susceptible to attack by the root-knot nematode (Meloidogyne hapla Chitwood), a pest that can severely reduce yields.
The Invention
UW–Madison researchers have developed inbred carrot lines that exhibit some resistance to Northern root-knot nematode. The two lines are [W261 x (Rotin x W259)] and [W77 x (Rotin x W259)]. The lines were identified via greenhouse screening tests in the presence of nematode infection. Genetic crosses indicated that resistance is conditioned by two different homozygous recessive genes.
Applications
- Genetic testing related to root-knot nematode resistance
- Potentially breeding a new commercial carrot line
Key Benefits
- Carrots show some resistance to Northern root-knot nematode.
