Posters and Oral Presentations


We would like to invite all graduate students and postdocs to submit a poster for the National Association Plant Breeders meeting.

Advanced graduate students and post-docs are encouraged to compete for three 15-minute invited speaker slots. The NAPB Education Committee will rank eligible abstracts and select up to three winners. The winners will be reimbursed with a full travel scholarship to the meeting.

In addition to the oral presentation competition, there will be a poster competition at the meeting organized by the NAPB Education Committee. They will evaluate and acknowledge up to six outstanding posters with awards. Each poster presenter will have the option to give a one-minute elevator talk during the meeting (limited slots available). To be eligible for the competitions, the presenting author must either be a graduate student or a post-doctoral researcher who earned his/her PhD between 2013 and 2015.  Each registrant is encouraged to submit a research poster, which will be displayed at the meeting, regardless of their eligibility for the competitions.

In order to present a poster, the presenting author must do the following by June 10, 2016

  1. Register for the meeting
  2. Complete the Abstract submission and data sheet
  3. Receive an email indicating that the abstract has been approved

Poster Information

  1. Maximum dimensions per poster: 48 inches high x 42 inches wide
  2. Poster boards will have Velcro backing, so please bring Velcro to affix posters to boards.
  3. Recommendations:
    • Presenters - include a small picture of yourself on your poster so that interested viewers can recognize you if they have questions for you.
    • Provide a one-page handout of your poster for interested viewers to take home.
    • Practice delivering a succinct summary of your project.
  4. No electrical outlets, tables, or chairs will be provided for poster displays.
  5. Recommendations to enhance the readability of posters include using 2- to 3-inch title lettering, numbered figures, and at least 14-point caption text. In general, the most effective posters lean toward simplicity, not complexity.

An increasing interest in the antioxidant capacity of vegetables has led to the development of novel potato clones. However, little is known about the effect of production environment on antioxidant levels in potato. The main purpose of this study was to determine the effect of genotype  and  environment  on  antioxidant  activity  of  potato  tubers.  In  this  study,  three replications of 22 high antioxidant breeding clones (developed by C. Brown) and three controls (Yukon Gold, Russet Burbank, and Snowden) were planted in four environments: organic (no irrigation), organic (irrigation), conventional (central sands), and conventional (northern Wisconsin). Samples of freshly harvested tubers were diced into 1 cm cubes (including the pel), frozen in liquid nitrogen, and stored at -80°C until analysis. In addition, tuber samples were stored  at  5.6°C  for  four months  and  processed  similarly.  The  TEAC  (Trolox  equivalent antioxidant capacity) assay for evaluating antioxidant levels in human tissue was adapted for tuber tissue. Antioxidant activity was determined for all clones at all sites for both fresh and stored tubers. Antioxidant activity of fresh tubers at all locations was higher in 2006 than in 2005. Cooler late-season temperatures in 2006 may have been responsible for the increased levels of antioxidants.   Stored tubers had higher levels of antioxidant activity than fresh tubers, with a larger storage effect in 2005, when antioxidant levels in fresh tubers were lower. There was no consistent effect of production system (organic versus conventional) on antioxidant activity in tubers.  For the specialty potato clones we evaluated, antioxidant levels were generally highest in potatoes grown in high-yielding production environments, and they increased during storage. Therefore, potatoes with high nutritional value, in terms of antioxidant activity, can be produced using conventional production and storage systems.
