- Abstract
Six mutant cms HA 89 lines, cms PI 432513 from a native American variety, and the French cms PET1 in an HA 89 background were compared in replicated yield trials at Fargo, ND and Casselton, ND in 2003 and 2004. Data collected included lodging %, days to flower, days to maturity, plant height, head diameter, yield, test weight, seed moisture content, and oil concentration. Differences among the eight cms lines for lodging, days to maturity, head diameter, yield, and oil % were not significant. The other traits were significant among lines, but most of them were not significantly different from cms HA 89, with a maximum days to flower of 2 days later, plant height up to 9 cm taller, test weight from 2.8 kg/hl less to 1.2 kg/hl more, and 1000 seed weight from 2.6 g less to 6.0 g more. The six new cms lines are therefore considered agronomically equal to the French cms PET1. F1 hybrids of these eight cms lines pollinated with oilseed restorer, RHA 274, and confectionery restorer, RHA 294, were also evaluated in separate yield trials. A similar interpretation for the parental cms lines can be made for the hybrids. The use of one oilseed restorer RHA 274, and one confectionery restorer RHA 294 contributed to the significant differences in days to flowering, plant height, test weight, 1000 seed weight, and oil %. However, the F1 deviations involving the new cms lines from cms HA 89 are within the acceptable levels of most breeding programs. Based on our results, the seven new cms appear equal to, if not better than, the French cms PET1 cytoplasm for hybrid sunflower production. Since new restoration lines will not be required, the new cms lines could be quickly utilized by the sunflower industry.
