| 0 | PI 634546 | NPM-5 | Cenchrus americanus (L.) Morrone | Nebraska, United States | S9 | | | 2004 | DEVELOPED | | | | | | Breeding material | Maturity medium early, dwarf, tillering A4and germplasm 66-104 cm in height. Flowers 57-68 d after early June to early July plantings at Mead, NE. Pollen shedding counts indicate that 99-100% of plants are male fertile. Gives 61-93% male fertility restoration in hybrids with two A4 male sterile lines. Grain yields of 1600-2800 kg/ha have been recorded. Grain yields topcross hybrids with 2 seed parent lines were 64%, 22%, and 38% higher than in early, normal, and late plantings, respectively. Seed gray in color, variable in shape with a size range of 5.9-13.8 g/1000. Panicles range in size from 14-29 cm in length (21.6 cm mean) and 2.2-3.7 cm in diameter with good exertion and segregate for bristles. | 1651233 | PI 634546 |
