Using new techniques and applying them to sunflower’s problems – what should we do next?

Brent Hulke Abstract: This presentation was part of a larger panel discussion with a largely non-scientific audience that included commodity marketers and farmers of sunflower. About 200 people were in attendance. Marker-assisted technologies were explained in lay terms to the audience. Their weaknesses and strengths were discussed. A few of the projects that the sunflower […]

Using interspecific hybrids with Helianthus tuberosus L. to transfer genes for quantitative traits into cultivated sunflower, H. annuus L.

Brent Hulke and Donald Wyse Abstract: Interspecific hybrids in sunflower have been used historically as sources of disease resistance. Backcrossing for several generations is required to introgress genes from hexaploid species to annual sunflower (Helianthus annuus L.). A result of this repeated backcrossing is the rapid loss of genes from the donor parent. This article

Advances in the development of sunflower germplasm with resistance to both Sclerotinia stalk rot and head rot – 2007

Thomas Gulya Jr. and Brent Hulke Abstract: Sclerotinia diseases remain the most significant of all diseases on both oilseed and confection sunflower production in the U.S. In 2007 Sclerotinia stalk rot and head rot affected 30% and 26%, respectively, of fields surveyed in North Dakota, South Dakota, Minnesota, Kansas, Colorado and Texas. Stalk rot and
