The UW Corn Silage and Biofeedstock Breeding Program, includes one of the only silage breeding program in the U.S. public sector. This program has created unique germplasm specifically designed to produce high-quality inbreds for use as parents for silage hybrids. Our program is also dedicated to determining the most appropriate germplasm for use as fermentable feedstock for energy production. Our objectives are:
The program is a broad-based effort including research on breeding, crop management, animal nutrition, and cell wall compositional analysis. We encourage critical review of our work so that we can incorporate new information on silage and biofeedstock productivity, quality, and germplasm that will be relevant and readily available to all.
The UW Corn Silage and Biofeedstock Breeding Program has one additional benefit that is critical for the continued success of the corn breeding industry. It is an outstanding training opportunity for graduate students to become thoroughly acquainted with the breeding procedures used to produce hybrids.

Four inbred lines have been released this year. W613S (40168-1-1-3-1-1) and W614S (40262-1-1-1-2-1-B) were developed from cycle 3 of the Wisconsin Quality Synthetic (WQS C3) population. W615S (50197-1-1-2-2-2-B) was developed from cycle 0 of the GEM Quality Synthetic (GQS C0) population. W616S (AR16026:S1719-052-2-B-B-B-20-1-1-1-B) was developed from the breeding population identified as AR16026:S1719-052 provided by the USDA Germplasm Enhancement of Maize (GEM) project. These lines were selected on the basis of high forage yield, neutral detergent fiber (NDF), in-vitro dry matter digestibility (IVD), and high protein and starch concentrations. In addition, these lines provide adequate maturity and good overall plant health.
Five inbred lines were developed from germplasm provided by the USDA GEM project and released in 2009 (W606S, W607S, W608S, W609S and W610S). Two inbred lines were developed from WQS C2 and released in 2009 (W611S and W612S).
In 2006, the performance of W601S-W604S hybrids were valuated in trial NEWINB. Hybrids involving W604S were included as checks in a number of other silage trials. Hybrids involving W601S, W602S, and W604S were evaluated in the 2006 UW Corn Performance Trials conducted by the UW Corn Extension program. The new hybrids were designated:
In 2005, the performance of W601S-W604S hybrids were evaluated in trial NEWINB. Hybrids involving W604S were included as checks in a number of other silage trials. Hybrids involving W601S, W602S, and W604S were evaluated in the 2005 UW Corn Performance Trials conducted by the UW Corn Extension program. The new hybrids were designated:
W605S was released in late 2004.
In 2004, the performance of W601S-W604S was evaluated in trial NEWINB. These inbreds also appeared in trials HC33, LH198, LH227, and LH244. Hybrids involving W602S and W604S were evaluated in the 2004 UW Corn Performance Trials conducted by the UW Corn Extension program. The hybrids were designated:
Four inbred lines from WQS C0 and C1 were released in 2003. W601S (S5 = 53062-2-11-1-1) was developed from WQS after the first cycle of selection. W602S (S5 = 80063-1-2-3-1), W603S (S5 = 80259-2-2-1-1) , and W604S (S5 = 80353-2-3-5-1) were developed from WQS after the second cycle of selection. Selection for all lines was initiated at the S2 stage of inbred development, at which time they were evaluated in topcrosses to LH119 (W601S) and LH198 (W602S, W603S, and W604S). These lines were also topcrossed at the S5 stage to inbreds LH198 and HC33. The topcrosses were evaluated in several field environments and selected on the basis of forage yield, neutral detergent fiber (NDF), in vitro true digestibility (IVD), in vitro NDF digestibility (NDFD), protein, starch, and, as a result, milk production potential. W601S – W604S are approximately 50% Lancaster background and 50% broad-based high-quality germplasm from northern temperate regions. The inbred lines combine well with lines derived from the Stiff Stalk heterotic background to provide average to high yielding hybrids with good nutritional quality.
If you are interested in our silage germplasm contact Natalia de Leon (ndeleongatti@wisc.edu). If you would like to receive inbred or hybrid seed, you will have to fill out a Material Transfer Agreement that is available from WARF. Breeding populations are available with a licensing agreement. Refer to the Germplasm page for more information.
