2009 Trials – List

AR16026 | AR17056 | DK212T | DK888 | GUAT209 | GQSC0 | WQSC2 | WQSC3

AR16026

One trial involving GEM material (09AR16026) was planted in 2009 at two WI locations, Madison (May 6th and 12th) and Arlington (June 1st). This trial was planted in triplicates in each of the locations with an average planting density of 32,800 plants/acre. Temperatures after planting were slightly below normal for both locations, but percent emergence did not appear to be affected by it. July of this year was the coldest July on record for our locations in the state of Wisconsin. Some lodging was observed primarily at the Arlington location. A very cool and wet Fall season provided for a very difficult and late harvesting season this year.

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 three advanced inbred lines from GEM population FS8B(T):N11a-322-1-B-B testcrossed by Holdens testers LH244 and LH332. Seven different hybrids were also included as checks.

GQSC0

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 31 advanced inbred lines from the GQS C0 population crossed to Holdens’ tester LH287 and W604S. This trail also included eight hybrid checks.

Trial GQSC0 was planted in 2009 at two WI locations, Madison (May 6th and 12th) and Arlington (June 1st). This trial was planted in triplicates in each of the locations with an average planting density of 32,800 plants/acre. Temperatures after planting were slightly below normal for both locations, but percent emergence did not appear to be affected by it. July of this year was the coldest July on record for our locations in the state of Wisconsin. Some lodging was observed primarily at the Arlington location. A very cool and wet Fall season provided for a very difficult and late harvesting season this year.

This trial was planted in triplicates in each of the locations with an average planting density of 32,800 plants/acre. Temperatures after planting were slightly below normal for both locations, but percent emergence did not appear to be affected by it. July of this year was the coldest July on record for our locations in the state of Wisconsin. Some lodging was observed primarily at the Arlington location. A very cool and wet Fall season provided for a very difficult and late harvesting season this year.

Trial GUAT209 consisted of the silage evaluation (yield and quality) of 57 inbred lines from the GEM program derived from population GUAT209:S1308a-135-001-B, GUAT209:S1308a-084-001-B and GUAT209:S1308a-013-001-B crossed to Holdens’ tester LH279.
