Narrative
TXR2005-TBO is a tetraploid forage-type annual ryegrass (4n = 4x = 28 chromosomes). This contrasts with Gulf and TAM 90 which are diploid cultivars. TXR2005-TBO is the first tetraploid cultivar released by the Texas Agricultural Experiment Station. The Oregon State Seed Laboratory tested TBO for ploidy level and reported it as 100% tetraploid. Plant stature of TBO was 116 cm and is larger and taller than Gulf, but similar to TAM 90. TBO averaged about 10 cm less in plant height compared to Jumbo and Prine in space plantings in Texas. Flag leaf length of TBO was 15.3 cm and was slightly longer than other cultivars which were 13.2, 11.7, and 13.8 for Gulf, TAM 90 and Jumbo, respectively. Leaf width was 10.6 mm for TBO and not different than Jumbo and Prine, but was 1 mm wider than TAM 90. TBO produced an average of 46 tillers per plant compared to 57, 61, 49, and 40 for TAM 90, Gulf, Jumbo and Prine, respectively. Freeze damage was not observed over the past two years at Overton, Texas when a low temperature of 17 F (-8 C) occurred. The fluorescence level of TBO according to the Oregon State Seed Testing Laboratory was 100 %. TBO has good crown rust resistance and is similar to TAM 90 for resistance to this disease. Total season forage yields of TBO at Overton, Texas have been very high during the 2004-05 and 2005-06 growing seasons. In each of these years, TBO has produced higher total season forage yields that any other commercial cultivars. TBO has also produced above average forage yields in Mississippi, Alabama and Georgia during the past two years. TXR2005-TBO is not infected with the fungal endophyte Neotyphodium occutans C.D. Moon, B. Scott, and M.J. Christensen, sp. Nov.

Pedigree
Description:
In 2001-02 a 3-way cross was made between TXR2000-T2, TXR2002-T17 and Jumbo . Jumbo is a tetraploid released by the Florida Agri. Exp. Stn. and the two experimentals tetraploids are derived from TAM 90 . In 2002-03, this seed was planted and grown in a space planting at Beaumont, Texas, where 34 plants were selected and allowed to cross-pollinate and produce seed. In 2003-04, this seed was grown and increased near Corvallis, Oregon and was designated TXR2005-TBO.
