of plants are male fertile. Gives 61-93% male fertility restoration inhybrids with two A4 male sterile lines. Grain yields of 1600-2800 kg/hahave been recorded. Grain yields topcross hybrids with 2 seed parentlines were 64%, 22%, and 38% higher than in early, normal, and lateplantings, respectively. Seed gray in color, variable in shape with asize range of 5.9-13.8 g/1000. Panicles range in size from 14-29 cm inlength (21.6 cm mean) and 2.2-3.7 cm in diameter with good exertion andsegregate for bristles.PI 634547. Pennisetum glaucum (L.) R. Br.Breeding. NPM-6. GP-40. Pedigree - Derived from intermating 37 A4R4parental breeding lines. Maturity medium early, dwarf, tillering, 85-100cm in height. Flowers 58-69 d after early June to early July plantingsat Mead, NE. Pollen shedding counts indicate that 93-96% of plants aremale fertile. Gives 63-81% male fertility restoration in hybrids withtwo A4 male sterile lines. Grain yields of 1700-2700 kg/ha have beenrecorded. Grain yields topcross hybrids with 2 seed parent lines were25%, 27%, and 30% higher than in early, normal, and late plantings,respectively. Seed gray or white in color, variable in shape with a sizerange of 5.3-17.4 g/1000. Panicles range in size from 17-28 cm in length(22.5 cm mean) and 2.1-3.5 cm in diameter and have good exertion.The following were developed by Ismail Dweikat, University of Nebraska, 279Plant Sciences, Agronomy and Horticulture Department, Lincoln, Nebraska68583, United States.
