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") 9.00
No.3 (1 1/2 - 2") 5.80
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

The cost of planning these trials, doing the field work, running the data analysis,
and summarizing the results for this report was approximately $22,000 each for the
pickling and slicing cucumber trials (not including the costs for cooperators at
other locations).

Pickling Cucumbers
Brinestock Evaluation - 1990
1993 Stage 3 Pickle Trial

Introduction
Cucumbers from the third and fifth harvests (June 28 and July 5, respectively)
of the 1990 stage 3 spring pickling cucumber trial were each placed in one
brine tank at Mt. Olive Pickle Co. on June 29 and July 6. The tanks were purged
with nitrogen to remove excess carbon dioxide from the brine.
Methods
The 21 cultigens (cultivars and breeding lines) were evaluated for fruit quality
(shape, external color, texture, seedcell size, and lot uniformity), firmness,
bloaters, and other defects on January 16, 1990. Quality was evaluated by 9
judges: Sonny Coghill, Lawrence Crocker, Phil Denlinger, and Janet Turner (Mt. Olive),
Jerry Ferrell and Tim Smith (C. F. Cates), Ron Thomas (Vlasic Foods), Blake Johnson
(Asgrow Seed), and George Hughes (private consultant). Fruit quality was evaluated
using a rating (approximating 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 damage in a sample of 10 grade 3B fruits. Firmness
was measured by punching 10 grade 2B fruits with a Magness-Taylor tester
(having a 5/16" diameter tip).
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 show few significant differences among cultigens.
Other Cultigens Tested
We also had the opportunity to evaluate several new experimentals in grower
trials, which are shown below, along with a check. The quality of Ark.H-19
was worse than the others, with color, texture, and seedcell problems.

Stage 1 Pickling Cucumber Trial
1991
Todd C. Wehner and Rufus R. Horton, Jr.
Experiment Design
1. Two replications of 14 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 lbs/A (N-P-K) broadcast preplant and
30-0-0 lbs/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 17, and harvested once-over on June 10
(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
1991
The stage 2 pickle trial was not run this year.
Stage 3 Pickling Cucumber Trial
1991
Todd C. Wehner and Rufus R. Horton, Jr.
Experiment Design
1. A randomized complete block with 3 replications of 28 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 lbs/A (N-P-K) broadcast preplant and
30-0-0 lbs/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 17, and harvested 6 times (Mondays and Thursdays)
between June 3 and June 20.
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, and could be advanced to the next stage:

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,
21 is worst).
Correlation (yield with SWI1) = 0.96**
Correlation (yield with SWI2) = 0.95**
Correlation (yield with ARI1) = -0.44**
Correlation (yield with ARI2) = -0.60**
Stage 4 Pickling Cucumber Trial
1991
Todd C. Wehner and Rufus R. Horton, Jr.
Experiment Design
1. A randomized complete block with 3 replications of 21 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 lbs/A (N-P-K) broadcast preplant and
30-0-0 lbs/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 19, and harvested 6 times (Mondays and Thursdays)
between August 23 and September 10.
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, and could be tested next year:

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,
21 is worst).
Correlation (yield with SWI1) = 0.96**
Correlation (yield with SWI2) = 0.95**
Correlation (yield with ARI1) = -0.79**
Correlation (yield with ARI2) = -0.83**
Slicing Cucumbers
Stage 1 Slicing Cucumber Trial
1991
The stage 1 slicer trial was not run this year.
Stage 2 Slicing Cucumber Trial
1991
The stage 2 slicer trial was not run this year.
Stage 3 Slicing Cucumber Trial
1991
Todd C. Wehner and Rufus R. Horton, Jr.
Experiment Design
1. A randomized complete block with 3 replications of 21 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 lbs/A (N-P-K) broadcast preplant and
30-0-0 lbs/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 17, and harvested 6 times (Mondays and
Thursdays) between June 6 and June 24.
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 cultivars and lines performed well, and could be advanced
to next year's trials:

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).
z 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, 30 is worst).

Stage 4 Slicing Cucumber Trial
1991
Todd C. Wehner and Rufus R. Horton, Jr.
Experiment Design
1. A randomized complete block with 3 replications of 21 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 lbs/A (N-P-K) broadcast preplant and
30-0-0 lbs/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 19, and harvested 6 times (Mondays and
Thursdays) between August 27 and September 13.
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 cultivars and lines performed well, and could be advanced to next year's trials:

z SWI is a simple index calculated by averaging the performance of a cultigen
for yield; earliness; fruit shape, color, and overall potential; and disease
resistance. The index was calculated using 2 different methods of weighting
the traits (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,
14 is worst).
