About This Report
The data contained in this publication are made available to interested persons so
that they will be informed as to the nature and scope of our cucumber breeding
program. Since the results of the trials are based on one year's data, they
should be interpreted cautiously. Genotype ¥ environment interactions make it
likely that the performance of any given cultigen (cultivar or breeding line) will
be significantly different in other trials. Often, cultigens that perform well
for yield, earliness, fruit quality, or disease resistance in one trial will
perform significantly worse in other trials.
Other factors, known only to the researchers, may complicate the interpretation of
the results, making it difficult for others to interpret differences from one year
to the next. For example, the effect of seed lot, pollenizer, harvest labor,
irrigation, fertilizer, pollinating insects and weather patterns may cause some
test plots in the field to receive better or worse treatment than average.
Therefore, we urge caution in interpreting these data. Conclusions drawn by the
reader will be more accurate if they are of a general nature. For example, note
which cultigens performed in the top third for yield, rather than which one was at
the very top.
Pricing schemes
Value of production figures were obtained by assigning the following prices
for the marketable grades:
Price
Grade per cwt
No.1 (< 1 1/16") $16.00
No.2 (1 1/16 - 1 1/2") 8.00
No.3 (1 1/2 - 2") 4.80
No.4 (> 2") 0.00
The pricing system is the one currently in use in North Carolina (averaged over
the spring and summer crops) and is revised annually. The same pricing systems
are applied to all production in a particular year even though commercial prices
for summer production are usually higher than for spring production.
Progression of breeding lines through trials:
Stage 1 trial Stage 2 trial Stage 3 trial Stage 4 trial
2 replications --> 1 replication --> 3 replications --> 3 replications
1 harvest 6 harvests 6 harvests 6 harvests

The cost of planning these trials, doing the field work, running the data
analysis, and summarizing the results for this report was approximately $48,000
for the brinestock, pickling and slicing cucumber trials. Printing and binding
charges were approximately $3.00 per report.

Pickling Cucumbers
Brinestock Evaluation - 1993
1993 Stage 3 Pickle Trial

Introduction
Cucumbers from the third and fifth harvests of the 1993 stage 3 spring
pickling cucumber trial were each placed in one brine tank at
Mt. Olive Pickle Co. The tanks were purged with nitrogen
to remove excess carbon dioxide from the brine.
Methods
The cultigens (cultivars and breeding lines) were evaluated for
fruit quality (shape, external color, texture, seedcell size,
and lot uniformity), firmness, bloaters, and other defects
in October. Quality was evaluated by judges from industry:
Sonny Coghill, Lawrence Crocker, Phil Denlinger, and
Janet Turner (Mt. Olive), Todd Bullock and John Tripp (Vlasic Foods),
and Curtiss Cates (Addis Cates Co.).
Fruit quality was evaluated using a rating system
(that approximated letter grades) from 1 to 9, where
9 = A+, 8 = A, 7 = A-, 6 = B+, 5 = B, 4 = B-, 3 = C, 2 = D, 1 = F.
Bloaters and defects were measured as percentage of fruits with damage
in a sample of 20 grade 3B fruits. Firmness was measured by punching
10 grade 2B fruits with a Magness-Taylor tester (having a 5/16" diameter tip).
All cultigens were randomized, replicated and coded to prevent bias
and provide a measure of error variance.
Results
The cultigens are presented in order by decreasing fruit quality in
Table 1, and are ranked for resistance to bloaters and defects in
Tables 2 and 3, respectively. Fruit texture and firmness rankings
are in Table 4. The average quality ratings assigned by each judge
in the test are presented in Table 5, showing how lenient each judge
was relative to the others. Due to insufficient replication, the
bloater data showed few significant differences among cultigens.
Summary
- The cultigens with best fruit quality in brinestock were UW 93-D,
Calypso, Eureka, Vlasset and PC-4.
- The most bloater resistant cultigens were Calypso, UW 93-E,
Atlantis, Neptune, Cross Country, Alexander, Pik-Rite, PSR 10588 and UW 93-D.
- As usual, brinestock firmness (from the punch test) was only
partially correlated with texture (subjective rating from the judges),
so the two traits are measurements of different aspects of cucumber
fruit firmness.
- Judges ranged from Coghill, who was the most liberal in quality ratings
to Bullock, who was the most conservative. Analysis of variance
indicated significant differences among judges for the way they
rated fruit quality. However, interaction of judge with cultigen
was non-significant (all judges gave good cultigens high, and
bad cultigens low quality ratings).

Stage 1 Pickling Cucumber Trial
1993
Todd C. Wehner and Rufus R. Horton, Jr.
Experiment Design
1. Two replications of pickle cultivars and breeding lines
(collectively referred to as cultigens) were grown.
2. Plots were single 5 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 July 1, and harvested once-over on August 23
(when the check plots had approximately 10% oversized fruits).
Results
The following cultigens performed well, and could be advanced to the next stage:

Stage 2 Pickling Cucumber Trial
1993
The stage 2 pickle trial was not run this year.
Stage 3 Pickling Cucumber Trial
1993
Todd C. Wehner and Rufus R. Horton, Jr.
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 April 28, and harvested 6 times
(Mondays and Thursdays) between June 10 and July 1.
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 = trace,
4 = first stem lesions, 9 = plant dead.

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) = 0.79** Correlation (yield with ARI1) = -0.62**
Stage 4 Pickling Cucumber Trial
1993
Todd C. Wehner and Rufus R. Horton, Jr.
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 July 1, and harvested 6 times
(Mondays and Thursdays) between August 12 and 30.
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 = trace,
4 = first stem lesions, 9 = plant dead.
Results

z SWI is a simple weighted index calculated by averaging the performance
of a genotype 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).
y ARI is the average ranking of each genotype 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) = 0.86** Correlation (yield with ARI1) = -0.43**
Slicing Cucumbers
Stage 1 Slicing Cucumber Trial
1993
Todd C. Wehner and Rufus R. Horton, Jr.
Experiment Design
1. Two replications of 24 cultivars and breeding lines
(collectively referred to as cultigens) were grown.
2. Plots were single 5 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 July 1, and harvested once-over on August 26
(when the check plots had approximately 10% oversized fruits).
Results
The following cultigens performed well, and could be advanced to the next stage:
1 Sprint 440 Asgrow Seed
2 Dasher II PetoSeed
3 Coolgreen Asgrow Seed

Stage 2 Slicing Cucumber Trial
1993
The stage 2 slicer trial was not run this year.
Stage 3 Slicing Cucumber Trial
1993
Todd C. Wehner and Rufus R. Horton, Jr.
Experiment Design
1. A randomized complete block with 3 replications of 31 slicer 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 April 27, and harvested 6 times
(Mondays and Thursdays) between June 14 and July 1.
Data Collection
1. Fruit were weighed after sorting into No. 1, No. 2 and cull
(nubs and crooks) grades according to U.S.D.A. standards.
2. Fruit length, diameter and weight were recorded for 3 fruit per plot.
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 = trace,
4 = first stem lesions, 9 = plant dead.
Results
The following cultigens performed well in their length class,
and could be advanced to the next stage:
