AR16026

One trial involving GEM material (AR16026) was planted in 2010 at two WI locations, Madison (May 6th and 10th) and Arlington (May 20th and 24th). This trial was planted in triplicates in each of the locations with an average planting density of 32,800 plants/acre. Temperatures throughout the spring and summer were above average for our area. A rapid accumulation of growing degree days was noted throughout the season. No major lodging problems were observed this year. Due to mechanical malfunctions, significant delays occurred during harvesting primarily for the Arlington location. Advancement decisions were done using primarily the West Madison yield and dry matter data.

Trial AR16026 consisted of the silage re-evaluation (yield and quality) of seven advanced inbred lines from the GEM program derived from the AR16026:S1719-052-2-B-B-B population testcrossed by Holdens tester LH287 and UW line W604S. Eleven different hybrids (including commercial and internal) were also included as checks.

Due to mechanical malfunctions, significant delays occurred during harvesting primarily for the Arlington location. Advancement decisions were done using primarily the West Madison yield and dry matter data.

In 2005, a new breeding population derived from GEM-derived sources of germplasm was initiated. This population is designated the GEM Quality Synthetic (GQS). GQS is approximately 75% Stiff Stalk. The aim is to create inbred lines from GQS that produce silage hybrids with high forage yield as well as superior nutritional quality when crossed to inbred lines from our non-Stiff Stalk Wisconsin Quality Synthetic (WQS) breeding population. Trial GQSC0 consisted of the silage evaluation (yield and quality) of 16 advanced inbred lines from the GQS C0 population crossed to Holdens’ tester LH287 and W604S, for a total of 32 entries in this trial. Twelve different hybrids (including commercial and internal) were also included as checks.
