Summer (Stage 4) 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 16 July, and harvested 5 times
(Mondays and Thursdays) between 27 August through 10 September.
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 10 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:
1 Patton (3528) SunSeeds
2 Calypso NCState Univ
3 Raleigh NCState Univ
4 Arabian Seminis
5 HMX-0469 Harris Moran
6 Vlaspik Seminis
7 Cross Country (4318) Harris Moran

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) = -0.79**
