2008 Pumpkin Powdery Mildew
Resistance Variety Trial
University of Tennessee
Extension
Annette
Wszelaki, Vegetable Extension Specialist, and Craig Canaday,
Plant Pathologist
Objective:
To evaluate powdery mildew
resistance, yield, and fruit and stem characteristics, as
well as postharvest storability of experimental and
commercially available jack o' lanterns for production in
Tennessee.
What did we find?
The top yielder by weight
was an experimental variety from
Hollar Seeds called
HSR4710. It yielded an average of 43.8 tons/acre with 95%
marketable fruit and an average fruit size of 15 pounds.
The top yielder by number was also an experimental variety
from Hollar Seeds
called HSR4721. This variety averaged over 8,000 fruit per
acre with 98% marketable fruit and an average weight of 8
pounds per pumpkin.
Rounding out the top five are Camaro (Hollar
Seeds), Spartan (Seedway)
and Magic Wand (Harris
Moran).
Charisma, Magic Lantern and 20 Karat Gold had the highest
percentage of unmarketable fruit - all over 20%.
Pankow’s Field and Howden were two of the lowest yielding
varieties in the trial. Both are susceptible to powdery
mildew.
