The Hulke Lab has released three additional oilseed sunflower germplasms: RHA 485, RHA 486, and HA 487. These lines have been developed to provide similar diversity for resistance to Sclerotinia head and basal stalk rot and Phomopsis canker in a high yielding genetic background, as well as downy mildew resistance! These germplasms are available for industry and public researchers as well. Please contact Brent Hulke for further details.
