180, and 191 cm, respectively, compared with 185 cm for the check hybrid cmsHA 292/RHA 310. Days from planting to flowering of hybrids with RHA 329 to RHA 334 were 70, 69, 67, 72, 71, and 72 days, respectively, compared with 71 days for the check hybrid cmsHA 292/RHA 310. Percentage of achenes passing over a 50/160 cm (20/64 in.) round hole screen for hybrids with RHA 329 to RHA 334 were 73, 46, 54, 73, 63, and 57%, respectively, compared with 76% for the check hybrid cmsHA 292/RHA 310. All hybrids had distinct black and white achene color and striping, and were equal to the check hybrids in percentage of kernel. These lines produced hybrids that were significantly more uniform in height and flowering, and had more upright head positions than the check hybrids. Limited quantities of seed of each germplasm source are available from the Seedstocks Project, Agronomy Department, North Dakota State University, Fargo, ND 58105.
