Research Project:
DEVELOPMENT OF INBREDS, HYBRIDS, AND ENHANCED GEM BREEDING POPULATIONS WITH SUPERIOR SILAGE YIELD & NUTRITIONAL VALUE
Location: North Central Regional Plant Introduction Station, Ames, Iowa
Project Number: 3625-21000-050-03
Project Type:
Specific Cooperative Agreement
Start Date: May 10, 2004
End Date: May 09, 2009
Objective:
Develop superior silage germplasm from GEM sources to enhance silage quality and yield.
Approach:
Conduct agronomic and quality assessments in replicated yield trials in Madison and Arlington, WI. Traits measured include forage yield at 35% whole plant dry matter, neutral detergent fiber (NDF), in vitro digestibility of ND (IVNDFD), crude protein (CP), and starch. A selection index will be used based on potential milk production per acre. The following sources of germplasm will be used: 1) ~25 new GEM topcrosses based on 2003 GEM trial data, 2) ~160 topcrosses involving lines derived at the UW from GEM populations CUBA164:S15, CUBA117:S1520, URZM13085:N0204, ARZM17026:N1013, ARZM17026:N1019, SCRO1:N1310, CH05015:N15, and DKXL370:N11a20.
