Narrative
Dwarf annual ryegrass developed for overseeding warm season turf grasses in the autumn. Diploid (2n=2x=14 chromosomes). In seedling stage, has rolled leaves and no auricles. Plant stature is much shorter than forage type annual ryegrass and relatively shorten than Axcella and Panterra turf-type annual ryegrass. Mature plants at Overton, TX were 65 cm for Axcella 2 compared to 79 and 86 cm for Panterra and Axcella, respectively. Tillers very well. Mean flag leaf length was 13, 16 and 18 cm for Axcella 2, Panterra and Axcella, respectively. Mean awn length at Overton averaged 3.3 mm; however about 15% of plants have very short awns or are awnless. Seed width is approximately 1.7 mm and seed length is 6 mm. One thousand seed weight of Axcella 2 was 2.1 g compared to 2.4, 2.5 and 2.8 g for Panterra, Axcella and TAM 90, respectively. Coleoptile color upo emergence is green or purple. Anther color is 80% yellow and 20% purple. Turf growth rate, or turf height measured in the cold season from December through February in a turf trial at Overton indicated Axcella 2 was significantly shorter than Axcella and Panterra and not significantly different than Palmer IV and PhD. In turf trials at Overton and College Station, TX, Axcella 2 was similar to Panterra, but superior to Axcella. Has finer textured leaves than Axcella and Panterra. Has darker green leaf color compared to Axcella, but similar to Panterra; however may hold this color longer into the late spring than Panterra. In over seeded turf trials at Overtin, TX, began to transition out by 21 April, which is similar to Axcella and Panterra, but significantly earlier than perennial ryegrass cultivars. Exposure to -8?C in 2005 resulted in leaf tip freeze injury but all plants recovered. Not infected with fungal endophyte Neotyphodium occutans. Roots tested 92% positive for fluorescence.

Pedigree
Description:
In 1998-1999, 400 plants from breeding line, TXR98-DBDF (released as Panterra) were space planted at Overton, TX and 30 plants were selected, cross-pollinated and seed bulked. In 1999-2000, 23 late maturing plants out of 550 plants cross-pollinated and seed was bulked. In 2000-2001, 14 plants out of 500 were allowed to cross-pollinate and seed was bulked. In 2002-2003, 50 g of seed was sent to DLF-International Seeds and 500 plants were grown out at Corvallis, Oregon. 10% of plants which had poor seed yield potential, or were not uniform were eliminated from the population. The remainder of plants cross-pollinated, produced seed and seed was bulked under designation, TXR2003-TF1 and released as Axcella 2.
