While Sclerotinia head and basal stalk rot and downy mildew have long caused problems for the sunflower (Helianthus annuus L.) production industry, Phomopsis stem canker is a disease that is a growing issue in the United States. Our goal was to provide germplasms that contain resistance to one or more of these problematic fungi while also upholding necessary agronomic traits, including high yield and tolerance to imidazolinone herbicides. RHA 485 (Reg. no. GP-356, PI 690018) and RHA 486 (Reg. no. GP-357; PI 690019) are restorer inbred germplasms developed by pedigree method and testcross evaluation. RHA 485 has high-yield potential with high-oil content and low Phomopsis and Sclerotinia head rot incidences in the field. RHA 486 possesses high-yield potential, resistance to Phomopsis (average incidence near 0%), and low incidence of Sclerotinia basal stalk rot. HA 487 (Reg. no. GP-358, PI 690442) is a maintainer inbred line that has potential for high yield, with Sclerotinia head rot scores that are comparable to the best available checks. These lines were released by the USDA-ARS, Fargo, ND, to fill the need for germplasms with resistance to multiple diseases in addition to other important agronomic traits.
To test inferences derived from previous research in personality and creativity, 61 undergraduates were given a variety of personality measures and a group of 28 Ss were exposed to an authoritarian speech to see whether the speech would increase their liking of hostile humor. Although the authoritarian speech did not influence humor preferences, the personality correlates of complexity-simplicity preferences were consistent with research by Barron (1963) and others. Number of points on the polygons correlated .90 with subjective ratings of complexity by males and .92 with subjective ratings of complexity by females. Implications are discussed, including whether or not symmetry may be equated with simplicity and asymmetry with complexity.
The banded sunflower moth is one of the most pervasive insect pests of sunflower (Helianthus annuus L.) in North America, in large part due to its ability to overwinter in cold climates. The goal of this research is to provide germplasm containing resistance to infestation by the banded sunflower moth while retaining valuable traits, such as imidazolinone herbicide tolerance and high oleic acid content in the seed oil, along with suitable agronomic performance for the northern Great Plains climate and other similar climates where the banded sunflower moth is prevalent. HA 489 (Reg.no. GP-370, PI 691858) is a maintainer inbred germplasm developed by pedigree selection and testcross evaluation that can fill this need. HA 489 has high oleic acid composition, exhibits tolerance to imidazolinones, and provides resistance to banded sunflower moth infestation. This line was released by the USDA-ARS, Fargo, ND, to fill the need for sources of host-plant resistance to important insect pests.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
