Narrative
Tift 11 is a perennial at Tifton, GA (USDA zone 8a). It was significantly taller than 'Princess Caroline' in six of eight tests at three locations in GA (Tifton, Griffin, and Blairsville). Plant canopy diameter was significantly wider for Tift 11 in only three of eight tests in GA. In five tests it was equal to 'Princess Caroline' in canopy diameter. Tift 11 has an attractive reddish/purple color and was equal to 'Princess Caroline' in seven of eight tests. Helminthosporium leaf spot is known to affect some genotypes in this species but, this disease has not been observed at Tifton, Griffin, or Blairsville, GA on Tift 11. Leaves of Tift 11 are significantly shorter, narrower, and have less leaf area than leaves of 'Princess Caroline'. The narrow leaves give this cultivar a unique attractive appearance. Culm-leaf angle was significantly larger for Tift 11 compared to 'Princess Caroline which gives Tift 11 a lesser upright leaf structure. Tift 11 is pollen and seed sterile. No pollen or seed has been observed on plants flowering in the greenhouse during the winter (short days). Tift 11 survived -6 ?C for one night and 21 nights below 0 ?C in the field during the 2009-10 winter at Tifton. It has survived the winter temperatures of 60 d below 0 ?C and a low temperature of -8 ?C during the 2009-10 winter at Griffin. It has never survived in the mountains at Blairsville (lows of -15 ?C in 2009-1 O and 2010-11 winters).

Pedigree
Description:
In 2003, red tetraploid (2n = 4x = 28) pearl millet (Pennisetum glaucum, 04-94) was crossed with SC 125-2 [a Merkeron napiergrass (P. purpureum, 2n = 4x = 28) x PS 262 (P. squamulatum, 2n =Bx= 56) interspecific hybrid]. One vigorous plant (04-26-1) was selected in 2004. In 2004, 'Princess' napiergrass (2n = 4x = 28) was pollinated with 04-26-1. 05-11 was the 11th plant selected in 2005 from the 2004 cross. It has been tested as 05-11 or simply as 11 or Tift 11 since 2005.
