Technical Abstract: The USDA-ARS and the University of Georgia at Tifton, GA, cooperatively developed and released in December 2003 pearl millet (Pennisetum glaucum) parental line Tift 454. Tift 454 is used as the A1 restorer parent to produce TifGrain 102. Tift 454 was derived from a pollen shedding plant (2n=2x=14) selected from among 111 pearl millet plants in 1980 from a Tift 23 D2A1 [cytoplasmic-nuclear male sterile (cms) pearl millet] x MN23 [2n=6x=42 pearl millet x napiergrass (P. purpureum)] interspecific hybrid cross. Tift 454 was selected in the F13 generation in 1998. In each generation plants were selected for complete fertility restoration of the A1 cytoplasm, plant uniformity, agronomic characteristics and combining ability with other genotypes. Seeds of Tift 454 are brownish-grey. Plants are 0.8 to 1.0 m in height at maturity and are at 50% anthesis in 54 to 57 d after planting. Tift 454 (2n=2x=14) has one or more A’ –genome chromosomes from P. purpureum which are homologous to the A-genome chromosomes of pearl millet. Tift 454 shows high resistance to two root-knot nematodes, Meloidogyne areniaria and M. incognita.
