Abstract Submission Instruct 2012

This is a call for papers to be presented at the 96th Annual Meeting of The Potato Association of America. This meeting will be held August 12-16, 2012 at the Crowne Plaza Denver International Airport Convention Center, Denver, Colorado, USA.

PAA invites submission of papers dealing with all facets of the potato industry. A special grower-oriented session is planned for Monday during the symposium on Phosphorus and at least one of the oral presentation sessions where presentations dealing with PVY will be solicited. Applied research and extension-oriented submissions are encouraged for this half-day session. Graduate students who are PAA members are encouraged to enter the “Frank L Haynes Graduate Student Research Competition”. Members are required to submit abstracts for papers they wish to present, whether orally, as a poster, or in the Frank L Haynes Graduate Student Research Competition. Prior to submitting your abstract, please carefully read and follow the formatting guidelines outlined below.

At the annual meeting, all oral paper presentations will be of a uniform 15-minute length. Authors should plan a 12- to 14-minute presentation with the balance of time devoted to questions. Computer projectors will be available for PowerPoint presentations. Please bring your PowerPoint presentation (2007 or earlier version) on a portable USB drive. Display boards (48” x 36”) will be provided for the poster papers.

The abstracts for all papers (oral, poster and Graduate Student Competition) presented at the Annual Meeting will be published in a post-meeting issue of the American Journal of Potato Research. Abstracts of papers listed in the meeting program, but not presented, will not be published in the AJPR.

Abstracts will be accepted until April 16, 2012. Submit abstracts as an e-mail attachment to loretta.mikitzel@gnb.ca with “PAA Abstract” as the e-mail subject. You will receive an email acknowledging receipt of the abstract. Abstracts submitted after that date will be returned to the author.

Cultivar improvements for powdery scab resistance in the Colorado Cultivar Development Program

Davidson, Robert D., Andrew J. Houser, and David G. Holm. Colorado State University, SLV Research Center, 0249 East Rd. 9 North, Center, CO 81125, USA.

Powdery scab caused by the pathogen Spongospora subterranea has become a significant pest of concern for many Colorado potato producers. Because of this situation, the Colorado Cultivar Development Program has embarked on an approach to build resistance into many of the newer releases to both root galling and tuber symptom development. Using a greenhouse screening technique, numerous advanced selections have been evaluated for disease development. Currently, four of the newest russet selections have demonstrated excellent resistance to both root galling and tuber symptoms. These russets have shown essentially zero root galling incidence and no tuber symptoms. There have been dramatic improvements in the resistance of red skinned clones with several selections showing 40% less tuber symptom severity and up to 80% less unmarketable tubers than the control cultivars. The root galling index is equal to or substantially better than the controls as well. Finally, much work has been conducted on specialty type cultivars. These tend to be more susceptible to powdery scab because of their skin characteristics. Several advanced selections are demonstrating excellent resistance to tuber symptom development, but demonstrate less impact on root galling. There has been a 50 to 100% reduction in unmarketable tubers and 40 to 80% improvement in severity scores when compared to the controls. However, the root galling index has remained similar to the controls in most cases. By providing better sources of resistance to the producers, they should be in a position to better manage this disease and continue to provide high quality potatoes for the market.
