Registration of oilseed sunflower germplasms RHA 461, RHA 462, RHA 463, HA 465, HA 466, HA 467, and RHA 468 with diversity in Sclerotinia resistance, yield, and other traits

peer-reviewed journal publication, Sunflower /

Brent Hulke, Guojia Ma, Lili Qi, Thomas Gulya Abstract: Sclerotinia head and stalk rots [caused by Sclerotinia sclerotiorum (Lib.) de Bary] are among the most devastating diseases in sunflower (Helianthus annuus L.). Breeding for resistance to these diseases is complicated by the quantitative inheritance of the resistance, for which there are few genes of major […]

Registration of oilseed sunflower restorer germplasms RHA 476 and RHA 477, adapted for short season environments

peer-reviewed journal publication, Sunflower /

Brent Hulke, William May Abstract: Northward expansion and double crop use of sunflower (Helianthus annuus L.) is limited by the lack of commercial hybrids with early maturity. We seek to provide the sunflower industry with new, early maturing restorer inbred germplasms with high yield potential and favorable agronomic and seed oil traits, specifically resistance to

Genetic Architecture of Capitate Glandular Trichome Density in Florets of Domesticated Sunflower (Helianthus annuus L.)

peer-reviewed journal publication, Sunflower /

Qing-Ming Gao, Nolan C. Kane, Brent S. Hulke, Stephan Reinert, Cloe S. Pogoda, Silas Tittes, Jarrad R. Prasifka Abstract: Capitate glandular trichomes (CGT), one type of glandular trichomes, are most common in Asteraceae species. CGT can produce various secondary metabolites such as sesquiterpene lactones (STLs) and provide durable resistance to insect pests. In sunflower, CGT-based

Plant-herbivore and plant-pollinator interactions of the developing perennial oilseed crop, Silphium integrifolium

peer-reviewed journal publication, Silphium /

Jarrad Prasifka, Rachel Mallinger, Brent Hulke, Steven Larson, David Van Tassel Abstract:  Sampling in Kansas and North Dakota documented the plant-herbivore and plant-pollinator interactions of the developing perennial oilseed crop, Silphium integrifolium Michx. The larva of the tortricid moth, Eucosma giganteana (Riley), was the most common floret- and seed-feeding pest in Kansas, with infested heads

Lab Picnic!

Uncategorized /

Last weekend, our extended lab family held a picnic at Oak Grove Park, where we grilled, played frisbee golf, and rode Brian’s tandem bike. Despite a few frisbees hitting Anna and a parked car, and taking a permanent swim in the river, the get-together was a success!

Somatic Embryogenesis from Corolla Tubes of Interspecific Amphiploids between Cultivated Sunflower (Helianthus annuus L.) and Its Wild Species

peer-reviewed journal publication, Sunflower /

Xuelin Fu, Lili Qi, Brent Hulke, Gerald Seiler, Chao-Chien Jan Abstract: Somatic embryogenesis in vitro provides an efficient means of plant multiplication, facilitating sunflower improvement and germplasm innovation. In the present study, using interspecific amphiploids (2n=4x=68) between cultivated sunflower and wild perennial Helianthus species as explant donors, somatic embryos were induced directly from the surface of corolla
