Corn Breeding Population for New Silage Hybrids
Inventors: Natalia de Leon Gatti, James Coors, Dustin Eilert
The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in a population of corn that could be used to develop more nutritious silage hybrids with high dry matter yield.
Corn silage is a forage crop used for high energy feed on many dairy and cattle farms. The best corn for silage shares three main characteristics: high grain content, good yield and digestibility. An important metric is neutral detergent fiber digestibility (NDFD). It is estimated that every percent of NDFD is worth 0.6 pounds of milk.
UW–Madison researchers have developed gem quality synthetic cycle 1 (GQS C1) corn that could be used to breed improved inbred lines and silage hybrids. The researchers selected plants displaying high NDFD, high yield and 75 percent Stiff Stalk background.
- Development of high quality hybrids for silage production
- High neutral detergent fiber digestibility
- High dry matter yield
- Superior nutritional quality
- Could be crossbred with other corn lines optimized for northern climates
