TRIPLOID WATERMELON CULTIGEN EVALUATION
SPRING 2000

The concept oftriploid (seedless) watermelons was described first in the U.S. literature by Kihara
(1951) based on experimentation that began in 1939 in Japan. Seed for planting seedless
watermelons results from a cross between a tetraploid female parent, developed by treating diploid
lines with colchicine or by other means, and a diploid (normal) male parent. The resulting triploid
plants are sterile and do not produce viable seed. However, small, white rudimentary seeds develop
which are eaten along with the flesh just as immature seeds are eaten in cucumber.

Fruit enlargement in seeded fruit, including watermelon, is enhanced by growth-promoting
hormones produced by the developing seed. Growth hormones are lacking in seedless watermelons
so those agents must be provided by pollen. Since flowers on triploid plants lack sufficient viable
pollen to induce normal fruit set, diploid seeded watermelons are interplanted with triploids to serve
as pollenizers. An adequate bee population is necessary to insure that sufficient transfer of pollen
occurs. Seedless fruit (from triploid plants) tend to be triangular shaped without sufficient
pollination.

Although the procedure for production of seedless watermelons has been known for almost 50 years
and commercial varieties have been available for over 20 years, the interest in and acreage of
seedless watermelons has remained small in Florida until recently. Erratic performance, poor seed
germination, high seed costs, and inadequate varieties resulted in the lack of interest in seedless
watermelon production in the past, but most of these deterents have now been overcome. It is
estimated that seedless watermelon production now represents about 30% of the total production in
Florida.

Specialty vegetables are in high demand and seedless watermelons offer an attractive alternative for
discriminating consumers and the food service industry. Seedless watermelons are being actively
promoted by marketing organizations and seed companies to stimulate demand. At the same time,
new varieties are being developed that are superior to those previously available. Seedless
watermelons have been evaluated at this location annually since 1988 (Maynard and Gilreath, 1988;
Maynard 1989-1997 and Maynard and Wittman, 1998, 1999).

The objective of this trial was to evaluate the performance oftriploid watermelon cultigens under
west-central Florida conditions.

MATERIALS AND METHODS

Seeds of 50 triploid watermelon varieties or experimental lines (Table 1) were planted in a peat-lite
growing mix in planter flats (1 1/4 x 1 1/4 x 2 1/4 in. cells) on 27 January. The watermelon
transplants were grown by a commercial plant grower.

Soil samples from the experimental area obtained before fertilization were analyzed by the
University of Florida Extension Soil Testing Laboratory (Hanlon and DeVore, 1989): pH = 7.1
(target pH is 6.0) and Mehlich I extractable P = 160 (very high), K = 28 (low), Mg = 96 (high), Ca
= 854 (adequate), Zn = 11.3 (adequate), Cu = 6.6 (adequate), and Mn = 5.9 (adequate) ppm.

The EauGallie fine sand was prepared in early February by incorporation of 0-0.8-0 lb. N-P205-K20
per 100 linear bed feet (lbf). Beds were formed and fumigated with methylbromide:chloropicrin,
67:33 at 2.3 lb/100 lbf. Banded fertilizer was applied in shallow grooves on the bd shoulders at 3.1-
0-4.3 Ib N-P20-K20/100 lbf after the beds were pressed and before the black polyethylene mulch was
applied. The total fertilizer applied was equivalent to 148-40-206 lb N-P205-K20/A. The final beds
were 32-in. wide and 8 in. high, and were spaced on 9-ft centers with four beds between seepage
irrigation/ drainage ditches which were on 41-ft centers.

The transplants were set in holes punched in the polyethylene at 3-ft in-row spacing on 29 February.
The replicated plots were 27 ft long and had nine plants each and were repeated three times in a
randomized, complete block design. Diploid watermelons that were being evaluated were direct
seeded in beds on each side of two triploid watermelon beds on 22 February to serve as diploid
pollenizers. Plant stands recorded just before vines grew together showed no significant differences
among plots. Weed control in row middles was by cultivation and applications of paraquat.
Pesticides were applied as needed for control of silverleaf whitefly endosulfann and imidacloprid),
gummy stem blight (chlorothalonil and azoxystrobin), and lepidopterous larvae (Bacillus
thuringiensis, spinosad, and methomyl).

Watermelons were harvested on 15-25 May and 30 May 15 June. Marketable (U.S. No. 1 or
better) fruit according to U.S. Standards for Grades of Watermelons (U.S. Dept. Agr., 1978) were
separated from culls and counted and weighed individually. Fruit 10 lbs and larger were assumed
to be marketable. Tetraploid fruit, where they occurred, were not included in the marketable
category because they are not seedless. At least six fruit from each entry at each harvest were used
to determine soluble solids (a measure of sweetness) with a digital, hand-held refractometer, polar
and equatorial dimensions, rind thickness, flesh color, and the incidence and severity ofhollowheart
were noted. Cell separations, however slight, were noted as hollowheart, even though the fruit might
be commercially acceptable. Where possible, the resulting data were subjected to analysis of
variance and mean separation was by Duncan's multiple range test.











RESULTS AND DISCUSSION

Temperature (Table 2) during the experimental period from 22 February to 15 June was near normal
in March, April, and May, the principal growing months. Rainfall was less than normal every
month and sparse in early June.

Early yield, as represented by the first of two harvests, varied from 33 cwt/acre for Liliput (Hazera
SW-1) to 219 cwt/acre for DPSX 4586 (Table 3). Other entries, except Liliput, had yields similar
to those of DPSX 4586. Average fruit weights at the first harvest ranged from 9.9 lbs for Hazera
6009 (a minimelon) to 21.5 lbs for Tribute. Soluble solids concentrations varied from 11.4% in
XWT 8706 to 14.5% in EX 4590249 at the first harvest. The percentage of fruit sampled having
hollowheart at the first harvest ranged from 0 in 'Tri-X-Shadow' and DPSX 4573 to 100% in
W5052.

Total yields (Table 3) ranged from 398 cwt/acre for 'Liliput' to 1056 cwt/acre for 'Sunday Special'
(EMR-507). Only seven other entries produced yields significantly similar to those of 'Sunday
Special'. Average fruit weight for the entire season varied from 10.0 Ibs for 'Liliput' to 21.4 lbs
for W5052. The number of fruit per plant ranged from 1.8 for 'Revolution' to 4.0 for 'Sunday
Special'. Soluble solids concentrations varied from 12.7% for RWM 8089 to 14.8% for EX
4590249. Accordingly, soluble solids in all entries far exceeded the 10% specified for optional use
in the U.S. Standards for Grades of Watermelons to describe very good internal quality (U.S. Dept.
Agr., 1978). The incidence of hollowheart in the fruit sampled ranged from 0 ;n 'Tri-X-Shadow'
to 88% in W5052.

The distribution of fruit into weight classes is shown in Table 4. When triploid fruit are packed in
cartons, there is an advantage in having a high proportion of fruit in the 14 to 18 lb category. DPSX
4571, DPSX 4572, DPSX 4573, DPSX 4586, 'Freedom', 'Gem Dandy', 'Genesis', RWM 8096,
SCS-91E3, 'Slice n' Serve', SSX 835, 'Sugar Shack', 'Summer Sweet 5244', 'Summer Sweet 5544',
SWT 6703, SWT 8705, 'Trident', 'Tri-X-Palomar', 'Tri-X-Shadow', XWT 7703, and XWT 8707
produced over 40% of their fruit in this weight range. Fruit are graded into two or more sizes when
they are shipped in bins. Large fruit are useful for food service or as a precut product. For example,
W5052 produced 46% of its fruit weighing more than 18 lbs whereas many entries produced smaller
fruit.

SUMMARY

Seedless watermelon variety trials have been conducted at this location each spring season since
1988. The highest yields ranged from 507 cwt/A in 1996 (Maynard, 1996) to 1 i86 cwt/A in 1999
(Maynard and Wittman, 1999). In spring 1999, 1056 cwt/acre was the highest yield which greatly
exceeded the 821 cwt/A average high yield during the entire period.

Variety shape and rind patterns, based on observations in this trial, are shown in Table 1. Varieties
producing oval to oblong fruit may be more suitable for boxing than varieties producing round
melons. Generally, the striped melons are more attractive for the U.S. market than those with dark
stripes on a very dark green background, or those with a solid dark green rind.











Based on results of this and previous trials, triploid hybrids, in alphabetical order, that should
perform well in Florida include 'Constitution', 'Freedom', 'Genesis', 'King of Hearts', 'Millionaire',
'Revere', 'Summersweet 5244', 'Summersweet 5544', 'Tri-X-313' and 'Tri-X-Carousel', Tri-X-
Palomar, and Tri-X-Shadow. 'Triton', a yellow-flesh variety should be evaluated for that niche
market. Other varieties may perform well on individual farms.
