Posters
Each registrant is encouraged to submit a research poster, which will be displayed throughout the
meeting. Abstracts of posters submitted to mjhavey@wisc.edu by August 2, 2010 will be
included in proceedings of the meeting.
Abstract Preparation
1. The abstract must contain the following information.
Centered on the page:
o Title of abstract (all in capital letters). Do not use bold face.
o Names and institutional affiliations of authors (first name or initials, followed by
last name). An asterisk should indicate the presenting author.
Left and right justified, single-spaced:
o Abstract body, including significance of the work, objectives, methods, results, and
conclusions. Do not include references.
2. The abstract must be submitted as an MS Word for Windows or Adobe PDF file.
3. The entire document (title, author names, and body) must be at least one-half page and no
more than one page (8.5 by 11 inches) long with 1-inch margins, and single-column
layout using 12-point Times New Roman font.
4. An example of the correct abstract form is one the next page.
PLEASE FOLLOW THE TEMPLATE BELOW
Abstract Submission
1. Abstracts must be submitted by e-mail. Your submission will be acknowledged by e-mail
within 3 days of receipt. Questions concerning the status of submitted abstracts should be
sent to mjhavey@wisc.edu. In order to be included in the proceedings of the meeting,
abstracts must be received by August 2, 2010.
2. Send your abstract as an e-mail attachment to mjhavey@wisc.edu. In the subject line,
type "Abstract for PBCC meeting." Send your online submission from the same e-mail
address where you want to receive the confirmation reply.
Poster Presentations
1. Poster space will be 44” x 44”, and posters will be mounted using thumbtacks. No
electrical outlets, tables, or chairs will be provided for poster displays.
2. Recommendations to enhance the readability of posters include using 2- to 3-inch title
lettering, numbered figures, and 14-point caption text.
3. Please print out your poster before coming to the meeting.
NEW RELEASES FROM THE USDA ONION BREEDING PROGRAM

The United States Department of Agriculture (USDA) onion-breeding program, under the
direction M.J. Havey, is focused on development of populations, inbreds, and genetic stocks
from divergent germplasms. Three recent releases from the USDA program include B8667,
SKI-1, and OH-1. Inbred B8667 A&B is round in shape, dark red with color extending through
the internal rings, firm, with good scale retention and excellent storage quality when produced on
muck soils. This inbred has a soluble-solids content of 13.4% and is relatively pungent at 10.7
µM pyruvate per ml. The A line is a BC7. The long-day onion synthetic population ‘Onion
Haploid (OH)-1’ is a responsive control for programs interested in extracting gynogenic haploids
of onion. Plants from the relatively responsive inbreds B2923B and B0223B were evaluated for
gynogenic haploid production, and selected highly responsive plants were self-pollinated. S1
bulbs from the most responsive families were intercrossed in cages. Bulbs of this synthetic
population are yellow with good storage quality, and produced on average 12 gynogenic haploids
for every 100 flowers plated. All plants in OH-1 should be homozygous recessive at the malefertility restoration (Ms) locus, although this has not been evaluated. The long-day onion
synthetic population SKI-1 A&B was selected from ‘Sapporo-Ki’, an open-pollinated population
grown on the Japanese island of Hokkaido with relatively high frequencies of both S cytoplasm
and dominant alleles at Ms. This synthetic combines the earliness of Sapporo-Ki with
maintenance of cytoplasmic-male sterility. The cytoplasmic male-sterile A line is a BC5. Bulbs
of this synthetic population are yellow, very early maturing in Wisconsin, and have good storage
ability.
