Cumbo and the personnel at the Horticultural Crops Research Station, Clinton, NC. for help in maintaining and harvesting the trials. 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.

Brinestock Evaluation - 1995 Stage 3 Pickle Trial Todd C. Wehner and Rufus R. Horton, Jr.z Department of Horticultural Science North Carolina State University 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 and Douglas Behrend (Mt. Olive), John Tripp (Vlasic Foods), Tim Smith, Randy Martin and Phet Phonchanh (Dean Foods), and Curtiss Cates and John 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 Raleigh, Clinton, HMX 2468, HMX 3469, FMX-5021, WI6236Ax6625A, and Johnston. - The most bloater resistant cultigens were HMX 2468, Calypso, HMX 1463 and HMX 3471. - 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 Martin, 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). ________________________ zThanks to Mt.

Stage 1 Pickling Cucumber Trial 1995 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 10 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 13 July, and harvested 2 times, 5 and 11 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 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.

Correlation (Yield with SWI1) = 0.74** Correlation (Yield with SWI2) = 0.55** Stage 2 Pickling Cucumber Trial 1995 The stage 2 pickle trial was not run this year. Stage 3 Pickling Cucumber Trial 1995 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 1 May, and harvested 6 times (Mondays and Thursdays) between 22 June and 10 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 = 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: Medium L/D (Calypso class)- 1 Raleigh NC State Univ. 2 FMX-5020 Ferry-Morse 3 Sunre 3540 SunSeeds 4 FMX-4937 Ferry-Morse 5 UW 95C Univ.

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) = 0.90** Correlation (yield with ARI1) = -0.66** Stage 4 Pickling Cucumber Trial 1995 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 13 July, and harvested 6 times (Mondays and Thursdays) between 24 August through 11 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 = 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: Medium L/D (Calypso class)- 1 FMX-5020 Ferry-Morse 2 HMX 3469 Harris Moran 3 Sunre 3540 SunSeeds 4 Calypso NC State Univ. 5 HMX 2468 Harris-Moran 6 Vlasstar Asgrow Seed 7 XVC 12368 Asgrow Seed Long L/D (Regal class)- 1 Johnston NC State Univ. 2 Napoleon SunSeeds Table 22.

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) = -0.58** Slicing Cucumbers Stage 1 Slicing Cucumber Trial 1995 The stage 1 slicer trial was not run this year. Stage 2 Slicing Cucumber Trial 1995 The stage 2 slicer trial was not run this year. Stage 3 Slicing Cucumber Trial 1995 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 1 May, and harvested 7 times (Mondays and Thursdays) between 26 June through 17 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 = trace, 4 = first stem lesions, 9 = plant dead.

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) = 0.91** Correlation (marketable yield with ARI1) = -0.73** Stage 4 Slicing Cucumber Trial 1995 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 13 July, and harvested 7 times (Mondays and Thursdays) between 31 August and 21 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 = 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 Lightning Asgrow Seed 2 HMX 0431 Harris-Moran 3 Thunder Asgrow Seed 4 NCES1 population NC State Univ. 5 Poinsett 76 Cornell Univ. 6 Indy Petoseed 7 Dasher II Petoseed 8 NCEDS population NC State Univ.
