Brent S. Hulke, Qing-Ming Gao, Michael E. Foley Abstract: One of the primary goals for the oilseed sunflower (Helianthus annuus L.) industry is to provide novel oil products for human consumption. One oil profile of particular interest is high oleic and low saturated fat, because it combines high oxidative stability of the oil with a reduction […]
Lili Qi, Zahirul Talukder, Brent Hulke, Michael Foley Abstract: Downy mildew, which is caused by fungus Plasmopara halstedii (Farl.) Berlese & de Toni, is one of the most important diseases that affect sunflower production globally. Two downy mildew resistance genes, PlArg and Pl8, were discovered in the late 1980s. Over two decades, PlArg is still
Our lab is proud to announce the release four oilseed sunflower germplasms: RHA 478, 479, 480, and HA 481. RHA 478 is an imidazolinone tolerant, Sclerotinia head and basal stalk rot resistant, high oleic F8-derived F9 restorer oilseed sunflower line. RHA 479 is a Sclerotinia head rot and Phomopsis stalk canker resistant F8-derived F9 restorer

Jarrad Prasifka, Brent Hulke Abstract: The banded sunflower moth, Cochylis hospes Walsingham (Lepidoptera: Tortricidae), is a significant seed-feeding pest of sunflowers in North America. Though some wild Helianthus spp., interspecific crosses, and H. annuus cultivars (that precede hybrid sunflower breeding) have low susceptibility to banded sunflower moth, no apparent effort has been made to evaluate
Our lab is proud to have released a new restorer oilseed germplasm, RHA 477 as of November 18th. RHA 477 is a F7-derived F9 restorer oilseed sunflower line selected from the cross RHA 468/R-7009. RHA 468 is an imidazolinone herbicide tolderant, downy mildew resistant, oilseed restorer line (by USDA and NDAES), while R-7009 is the

This summer we had field locations in Courtland, MN; Glyndon, MN; Galchutt, ND; Mandan, ND; and Oakes, ND. The field locations made up about 25 acres that we completed our research on. Some of the highlights from our summer were: Testing out our new seed indexer for planting Laying out 9 miles of drip tape

One of our big projects this summer was funded by Genome Canada, and involved us having a dryland trial and a flood trial out near Oakes, ND. In order to set up the flood trial, we had to manually lay irrigation drip tape (totaling about 9 miles!) to simulate the flood environment. Below is a
