2014 University of Delaware Seedless Watermelon Variety Trial Gordon Johnson & Emmalea Ernest University of Delaware Elbert N. & Ann V. Carvel Research and Education Center 16483 County Seat Highway Georgetown, DE 19947 (302) 856-7303 [email protected] [email protected]
Introduction The 2014 Seedless Watermelon Variety Trial included 25 varieties from ten participating companies. The purpose of this trial is to evaluate seedless watermelon varieties for yield, quality and maturity.
Materials and Methods Location Field 12 D&E at the University of Delaware Research and Education Center Farm, Georgetown, DE. Cultural Practices Field was fertilized and limed according to soil test results (1 ton/A calcitic lime + 200 lbs/A 0-0-60). Prefar (bensulide) at 6 qt/A + 50 lbs/A of nitrogen (30% UAN) was applied after the beds had been shaped and before black plastic mulch and trickle irrigation were laid on 7’ centers. There were 25 entries in the trial this year. Plants were seeded in the greenhouse on April 15, 2014 and transplanted to the field on May 20 and 21, 2014. Field plots were one row (7 ft) wide and 30 ft long. Plots were arranged in a randomized complete block design with three replications. In-row spacing was 3ft or 10 plants per plot. Two plants of the in-row pollenizer variety ‘Accomplice’ and two plants of the in-row pollinizer ‘Sp-6’ were planted in each plot in the following arrangement: s A s s s 6 s s s A s s s 6. “A” designates Accomplice, “6” designates Sp-6 and “s” designates the seedless plants. The border rows next to the drive rows, which separated the replications, were planted in the triploid variety ‘SS 9651’, with the Accomplice and Sp-6 as the pollenizers, in the same arrangement as the experimental plots. ‘SS 9651’ has a solid medium green rind and was easily distinguishable from the trial entries. A the request of the entering seed company, the variety ‘Secretariat’ was planted with 4 plants per plot of the in-row pollinizer ‘ACE’ instead of Accomplice and Sp-6. An application of Gramoxone 2 qt/A +Sandea (halosulfuron) 0.75 oz/A + Sinbar (terbacil) 4 oz/A + Dual 1 pt/A + 1% Crop Oil was made to the row middles on May 30 with a hooded sprayer. Vines were turned before this application as they had just started to run off of the plastic. Plots were fertigated with 60 lbs/A of N on June 18 (32% UAN) and again on July 10 (30% UAN)

Applications for disease and insect control were as follows: 5-27: Assail 5 oz/A 6-2: Chlorothalonil 3 pt/A 6-13: Chlorothalonil 3 pt/A, Inspire Super 16 oz/A, Warrior II 2 oz/A 6-20: Chlorothalonil 3 pt/A 6-27: Chlorothalonil 3 pt/A, Tebuconazole 8 oz/A, Quadris 16 oz/A, Warrior II 2 oz/A 6-27: Select 8 oz/A for grass 7-4: Chlorothalonil 3 pt/A, Bifenthrin 6.4 oz/A, Oberon 8 oz/A, Pristine 18 oz/A 7-11: Chlorothalonil 3 pt/A, Inspire super 16 oz/A 7-18: Mancozeb 3 lb/A, Pristine 18 oz/A, Phostrol 4 pt/A, Bifenthrin 6.4 oz/A 7-25: Chlorothalonil 3 pt/A, Quadris 16 oz/A 8-2: Chlorothalonil 3 pt/A, Tebuconazole 8 oz/A 8-8: Chlorothalonil 3 pt/A, Inspire super 16 oz/A, Ranman 2.75 oz/A 8-15: Chlorothalonil 3 pt/A, Pristine 18 oz/A, Bifenthrin 6.4 oz/A 8-22: Chlorothalonil 3 pt/A, Ranman 2.75 oz/A Harvest Fruit were harvested two times: on August 6 & 7 and on August 19 & 20. The weight of each watermelon harvested was recorded individually. Five marketable watermelons from each plot were cut and evaluated for presence of hollow heart and soluble solids levels. Soluble solids were measured using a hand-held refractometer and hollow heart cracks were rated as absent (0), present but fruit is marketable (1) or present rendering fruit unmarketable (3).
Results Total yield, marketable yield excluding misshapen culls and fruit less than 9 lbs (Marketable Yield I) and marketable yield excluding misshapen culls, fruit less than 9 lbs and fruit over 24 lbs (Marketable Yield II) are reported in Table 1 in both pounds per acre and fruit per acre for each variety. The highest yielding varieties in the trial in terms of Marketable Yield I in lbs/A were Wolverine, Exclamation, Nun01009, Captivation, Crunchy Red, Premont, ORS 12166, Sweet Polly, Fascination and SV 0258 WA. Total Marketable Yield I of each variety, as well as Marketable Yield I in for each of harvests, are reported in Table 2 in lbs/A and in Table 3 in fruit/A. Table 4 reports the percent of total harvest for each harvest. This year, the first harvest was much later than typical for this trial (78 DAT versus the usual ~60 DAT) and the yield at first harvest was higher than usual. The first harvest was probably delayed because of cool weather in the early part of the season and stress from heavy disease pressure this year. We harvested a second time, two weeks after the first harvest. Typically we harvest this trial at least three times, but this year there was a lot of disease pressure, especially from Phytophthora fruit rot in the field and we chose to stop data collection after two harvests. Table 5 lists the varieties according to average fruit weight and gives the percentage of fruit in each of four weight classes: 60 count (9.0-13.5 lbs), 45 count (13.6-17.5 lbs), 36 count (17.621.4 lbs) and 30 count (>21.5 lbs). Fascination, Exclamation, Premont, Maxima, Tri-X 313, ZG0409, Wolverine and SV 0258WA produced the largest fruit. Troubadour produced the highest percentage of melons in the 60 count category. Wolverine produced the highest
2
percentage of melons in the 45 count category. Fascination produced the highest percentage of melons in the 36 count category. Premont produced the highest percentage of melons in the 30 count category. Table 6 lists the varieties according to their soluble solid measurements. Soluble solids averages are based on a 15-fruit sample (5 fruit per replication). There were significant differences in soluble solids among the varieties. All of the varieties had average soluble solids of over 10%. Table 7 lists the varieties according to the percent of fruit with hollow heart. Hollow heart averages are based on a 15-fruit sample (5 fruit per replication). There was some hollow heart observed in the trial this year. The varieties that were most affected were Sweet Gem, Sweet Polly, SWT 7829, SV 0258 WA, Fascination and Premont. No hollow heart was observed in Troubadour, HMX 1915, Crunchy Red, Captivation and Exclamation. Photographs of the varieties included in the trial are in Appendix A.

Introduction The 2014 Seedless Watermelon Variety Trial included 25 varieties from ten participating companies. The purpose of this trial is to evaluate seedless watermelon varieties for yield, quality and maturity.
Materials and Methods Location Field 12 D&E at the University of Delaware Research and Education Center Farm, Georgetown, DE. Cultural Practices Field was fertilized and limed according to soil test results (1 ton/A calcitic lime + 200 lbs/A 0-0-60). Prefar (bensulide) at 6 qt/A + 50 lbs/A of nitrogen (30% UAN) was applied after the beds had been shaped and before black plastic mulch and trickle irrigation were laid on 7’ centers. There were 25 entries in the trial this year. Plants were seeded in the greenhouse on April 15, 2014 and transplanted to the field on May 20 and 21, 2014. Field plots were one row (7 ft) wide and 30 ft long. Plots were arranged in a randomized complete block design with three replications. In-row spacing was 3ft or 10 plants per plot. Two plants of the in-row pollenizer variety ‘Accomplice’ and two plants of the in-row pollinizer ‘Sp-6’ were planted in each plot in the following arrangement: s A s s s 6 s s s A s s s 6. “A” designates Accomplice, “6” designates Sp-6 and “s” designates the seedless plants. The border rows next to the drive rows, which separated the replications, were planted in the triploid variety ‘SS 9651’, with the Accomplice and Sp-6 as the pollenizers, in the same arrangement as the experimental plots. ‘SS 9651’ has a solid medium green rind and was easily distinguishable from the trial entries. A the request of the entering seed company, the variety ‘Secretariat’ was planted with 4 plants per plot of the in-row pollinizer ‘ACE’ instead of Accomplice and Sp-6. An application of Gramoxone 2 qt/A +Sandea (halosulfuron) 0.75 oz/A + Sinbar (terbacil) 4 oz/A + Dual 1 pt/A + 1% Crop Oil was made to the row middles on May 30 with a hooded sprayer. Vines were turned before this application as they had just started to run off of the plastic. Plots were fertigated with 60 lbs/A of N on June 18 (32% UAN) and again on July 10 (30% UAN)

The weight of each watermelon harvested was recorded individually. Five marketable watermelons from each plot were cut and evaluated for presence of hollow heart and soluble solids levels. Soluble solids were measured using a hand-held refractometer and hollow heart cracks were rated as absent (0), present but fruit is marketable (1) or present rendering fruit unmarketable (3).
Results Total yield, marketable yield excluding misshapen culls and fruit less than 9 lbs (Marketable Yield I) and marketable yield excluding misshapen culls, fruit less than 9 lbs and fruit over 24 lbs (Marketable Yield II) are reported in Table 1 in both pounds per acre and fruit per acre for each variety. The highest yielding varieties in the trial in terms of Marketable Yield I in lbs/A were Wolverine, Exclamation, Nun01009, Captivation, Crunchy Red, Premont, ORS 12166, Sweet Polly, Fascination and SV 0258 WA. Total Marketable Yield I of each variety, as well as Marketable Yield I in for each of harvests, are reported in Table 2 in lbs/A and in Table 3 in fruit/A. Table 4 reports the percent of total harvest for each harvest. This year, the first harvest was much later than typical for this trial (78 DAT versus the usual ~60 DAT) and the yield at first harvest was higher than usual. The first harvest was probably delayed because of cool weather in the early part of the season and stress from heavy disease pressure this year. We harvested a second time, two weeks after the first harvest. Typically we harvest this trial at least three times, but this year there was a lot of disease pressure, especially from Phytophthora fruit rot in the field and we chose to stop data collection after two harvests. Table 5 lists the varieties according to average fruit weight and gives the percentage of fruit in each of four weight classes: 60 count (9.0-13.5 lbs), 45 count (13.6-17.5 lbs), 36 count (17.621.4 lbs) and 30 count (>21.5 lbs). Fascination, Exclamation, Premont, Maxima, Tri-X 313, ZG0409, Wolverine and SV 0258WA produced the largest fruit. Troubadour produced the highest percentage of melons in the 60 count category. Wolverine produced the highest

percentage of melons in the 45 count category. Fascination produced the highest percentage of melons in the 36 count category. Premont produced the highest percentage of melons in the 30 count category. Table 6 lists the varieties according to their soluble solid measurements. Soluble solids averages are based on a 15-fruit sample (5 fruit per replication). There were significant differences in soluble solids among the varieties. All of the varieties had average soluble solids of over 10%. Table 7 lists the varieties according to the percent of fruit with hollow heart. Hollow heart averages are based on a 15-fruit sample (5 fruit per replication). There was some hollow heart observed in the trial this year. The varieties that were most affected were Sweet Gem, Sweet Polly, SWT 7829, SV 0258 WA, Fascination and Premont. No hollow heart was observed in Troubadour, HMX 1915, Crunchy Red, Captivation and Exclamation. Photographs of the varieties included in the trial are in Appendix A.
