Tift 15 has an attractive reddish/purple color and was equal in color to 'Princess Caroline' in three of six tests and significantly better color in three tests. Helminthosporium leaf spot is known to affect some genotypes in this species but, this disease has not been observed at Tifton or Blairsville, GA on Tift 15. Leaves of Tift 15 are significantly longer but similar in width, and leaf area compared to leaves of 'Princess'. There was no significantly difference in culm-leaf angle Tift 15 and 'Princess'. Tift 15 is pollen and seed sterile. No pollen or seed has been observed on plants flowering in the greenhouse during the winter (short days). Tift 15 survived -6 ?C for one night and 21 nights below 0 ?C in the field during the 2009-10 winter at Tifton. It also survived -7 ?C for one night and 24 nights below 0?

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 05-15 or simply as 15 or Tift 15 since 2005.
