Spring (Stage 3) Pickling Cucumber Trial
2001
Todd C. Wehner and Tammy L. Ellington

Experiment Design
1.   A randomized complete block with 3 replications of pickle cultivars
     and breeding lines (collectively referred to as cultigens) was grown.
2.   Plots were single 20 ft. rows with 5 ft. alleys at each end.
3.   Rows were on raised 18" beds spaced 60" apart (center to center).
4.   Fertilizer consisted of 80-80-80 lb/A (N-P-K) broadcast preplant and
     30-0-0 lb/A (N-P-K) sideplaced at the 2 to 4 leaf stage.
5.   Curbit was applied preemergence at the rate of 1 lb. a.i./A.
6.   The trial was planted 21 May, and harvested 6 times
     (Mondays and Thursdays) between 5 and 23 July.

Data Collection
1.   Firmness was measured on 3 Grade 3 fruits using a Magness-Taylor tester
     with a 5/16" tip.
2.   Length/Diameter ratio was calculated by measuring 5 Grade 2 fruits.
3.   Quality ratings were from 1 to 9, with 1 = worst, 9 = best.
4.   Disease ratings were from 0 to 9, with 0 = no disease, 1-2 = trace,
     3-4 = slight, 5-6 = moderate, 7-8 = severe, 9 = plant dead.

Results
The following cultigens performed well, and could be advanced
to the next stage:

z SWI is simple weighted index calculated from the performance of a cultigen for
  yield; earliness; fruit shape, seedcell size and overall impression; and disease
  resistance.  The index is calculated with 2 different methods of weighting each
  trait (10 is best, 1 is worst).
ARI is the average ranking of each cultigen for yield, earliness, fruit quality
  and disease resistance.  The index is calculated with 2 different sets of
  secondary traits added in with the primary traits (1 is best).
Correlation (Yield with SWI1) = 0.95**
Correlation (Yield with ARI1) = -0.59**
