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

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 - 1994
Stage 3 Pickle Trial

Introduction
Cucumbers from the third and fifth harvests of the 1994 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 Janet Turner (Mt. Olive), Ron Thomas,
Todd Bullock and John Tripp (Vlasic Foods), Tim Smith and Chad Andexler (Dean 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 AR 91-46,
Sumter, UW 94-D and FMX-4934.
- The most bloater resistant cultigens were AR 91-46, Sumter, Nautilus,
Wis. SMR 18, WI6236Ax6469A and UW 94-H.
- 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 Crocker, who was the most liberal in quality ratings
to Thomas, 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).

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 21, and harvested 6 times
(Mondays and Thursdays) between June 13 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 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).
y 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) = 0.94** Correlation (yield with ARI1) = -0.72**
Stage 4 Pickling Cucumber Trial
1994
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 5, and harvested 6 times
(Mondays and Thursdays) between August 18 and September 6.
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
The following cultigens performed well in their L/D size class,
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).
y 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) = 0.96** Correlation (yield with ARI1) = -0.76**
Slicing Cucumbers
Stage 1 Slicing Cucumber Trial
1994
The stage 1 slicer trial was not run this year.
Stage 2 Slicing Cucumber Trial
1994
The stage 2 slicer trial was not run this year.
Stage 3 Slicing Cucumber Trial
1994
Todd C. Wehner and Rufus R. Horton, Jr.
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 April 21, and harvested 6 times
(Mondays and Thursdays) between June 16 and July 5.
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 = 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:
1 Thunder Asgrow Seed
2 Speedway Petoseed
3 Dasher II Petoseed
4 General Lee Ferry-Morse
5 Slice Nice SunSeeds

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).
y 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) = 0.89**
Correlation (marketable yield with SWI2) = 0.89**
Correlation (marketable yield with ARI1) = -0.74**
Correlation (marketable yield with ARI2) = -0.79**
Stage 4 Slicing Cucumber Trial
1994
Todd C. Wehner and Rufus R. Horton, Jr.
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 July 5, and harvested 6 times
(Mondays and Thursdays) between August 22 and September 9.
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:
