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:
Spring Summer
Grade $/cwt $/cwt
No.1 (< 1 1/16") $16.50 $17.25
No.2 (1 1/16 - 1 1/2") 8.50 9.25
No.3 (1 1/2 - 2") 5.75 6.50
No.4 (> 2") 0.00 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
spring season summer season

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 - 1998
Stage 3 Pickle Trial

Introduction
Cucumbers from the third and fifth harvests of the 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, Bob Quinn, and Tim Smith (Mt.
Olive), Jacob Ezzell and Walter Williams (Dean Foods), Curtiss Cates and
John Cates (Addis Cates Co.), Wayne Downes and Dave Hall (B & G Foods),
Steve Apol (Bicks Pickles), and Richard Wojciak (SunSeeds).
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 Clinton, Vlasstar,
Calypso, WI6842Ax6760B, Cross Country, UW 98 Q and UW 98 R.
- The most bloater resistant (free of balloon and lens bloating) cultigens
were Vlasstar, Calypso, UW 98 Q, Cross Country, WI6842Ax6760B, Raleigh,
and Shenandoah.
- 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 Apol, who was the most liberal in quality ratings to
Hall, 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 ratings, and bad cultigens low ratings).

Stage 1 Pickling Cucumber Trial
1998
Experiment Design
1. A randomized complete block with 2 replications of pickle cultivars
and breeding lines (collectively referred to as cultigens) was grown.
2. Plots were single 4 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 1 June, and harvested twice, 20 and 27 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.

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).
Correlation (Total yield with SWI1) = 0.83**
Correlation (Total yield with SWI2) = 0.75**
Stage 2 Pickling Cucumber Trial
1998
The stage 2 pickle trial was not run this year.
Stage 3 Pickling Cucumber Trial
1998
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 30 April, and harvested 6 times
(Mondays and Thursdays) between 15 June and 2 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) = 0.93**
Correlation (Yield with ARI1) = -0.72**
Stage 4 Pickling Cucumber Trial
1998
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 6 July, and harvested 4 times
(Mondays and Thursdays) between 20 August through 8 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 Vlaspik Seminis Veg.
2 Calypso NC State Univ.
3 Shenandoah Harris Moran
4 SRQP-1888 SunSeeds
5 Patton SunSeeds
6 XPH-1901 Seminis Veg.

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) = 0.92**
Correlation (Yield with ARI1) = -0.70**
Slicing Cucumbers
Stage 1 Slicing Cucumber Trial

The stage 1 slicer trial was not run this year.
Stage 2 Slicing Cucumber Trial
1998
The stage 2 slicer trial was not run this year.
Stage 3 Slicing Cucumber Trial
1998
Todd C. Wehner and Tammy L. Ellington
Experiment Design
1. A randomized complete block with 3 replications of 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 30 April, and harvested 6 times
(Mondays and Thursdays) between 22 June through 9 July.
Data Collection
1. Fruits 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, 1-2 = 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 Panther SunSeeds
2 Daytona Seminis Veg.
3 Greensleeves Harris Moran
4 Dasher II Seminis Veg.
5 General Lee Harris Moran
6 Jade 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 (Marketable yield with SWI1) = 0.96**
Correlation (Marketable yield with ARI1) = -0.74**
Stage 4 Slicing Cucumber Trial
1998
Todd C. Wehner and Tammy L. Ellington
Experiment Design
1. A randomized complete block with 3 replications of 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 6 July, and harvested 3 times
(Mondays and Thursdays) between 24 August through 11 September.
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, 1-2 = 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 (Marketable yield with SWI1) = 0.94**
Correlation (Marketable yield with ARI1) = -0.74**
