Narrative
Tift 40 is a perennial at Tifton, GA (USDA zone Ba). It was significantly taller than 'Princess Caroline' in six of seven tests at three locations in GA (Tifton, Griffin, and Blairsville). The 2011 plants of Tift 40 were significantly shorter, probably due to the severe 2010-11 winter. Tift 40 is very vigorous from new planting, but of all the sister lines from the cross, it appears to be the most cold susceptible. Plant canopy diameter was significantly wider for Tift 40 than 'Princess Caroline' In only three of seven tests in GA. Tift 40 has an attractive reddishfpurple color and was equal in color to 'Princess Caroline' in three of seven tests and had significantly better color In four tests. Helminthosporium leaf spot is known to affect some genotypes in this species but, this disease has not been observed at Tifton or Griffin, GA on Tift 40. Leaves of Tift 40 are significantly longer, wider, and have more leaf area than leaves of 'Princess Caroline'. The long drooping leaves give Tift 40 and attractive appearance. Culm-leaf angle was significantly less for Tift 40 compared to 'Princess Caroline. Tift 40 is pollen and seed sterile. No pollen or seed has been observed on plants flowering in the greenhouse during the winter (short days). Tift 40 survived -6 'C for one night and 21 nights below 0 'C in the field during the 2009-10 winter at Tifton. It did not survive -7 OC for one night and 24 nights below 0? C in the field during the 2010-11 winter at Tifton. It has not survived the winter temperatures at Griffin or Blairsville, GA.

Pedigree
Description:
In 2003, red tetraploid (2n = 4x = 28} pearl millet (Pennisetum glaucum, 04-94) was crossed with SC 1125-2 [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. 05-40 was the 4oth plant selected in 2005 from the 2004 cross. It has been tested as 05-40 or simply as 40 or Tift 40 since 2006.
