Watermelon Varieties for Florida

GqWJ-Elms. trom :
Field trials of-watearmelon varieties hav\een cond ted on Astatula
fine sand at the Agricultural Researc cCkfiter, Leesb rg since 1969.
Direct-seeded plants were spaced aj;'4 feet A4frows 10 feet apart.

Several fertilizer programs have\been f',oowed during" .'te seven-year
period. Over the years 120 to 14, pounds of N a 1iO0 and 100 to
160 pounds of P205 were applied per acre. PFri t'd "icronutrients
were applied at a rate of 25 to 35 pounds- per acre each year. None
of the land could be considered newly sBtne '*'termelons had been
grown on the land wit.'iJn the past 6 t, ---years.

'Charleston Gray'. 'Jubilee', and 'Crimson Sweet' continue to be the
three most important -. .-"ial varieties grown in Florida. Acreage
of 'Crimson Sweet' and 'Jubilee' has increased somewhat in recent
years and often a premium of one-half to one cent per pound is paid
for these varieties.

Recently, Fusarium wilt has caused serious losses in many fields of
'Charleston Gray' and 'Jubilee'. In 1971 and 1972, tests for wilt
resistance in 'Jubilee' from commercial seed stocks indicated a
lower level of resistance than that in the original "breeder" seed.
Loss of wilt resistance in 'Jubilee' was most likely the result of
seed being increased in areas with low or no selection pressure for
Fusarium wilt. Increases of 'Jubilee' seed from breeder stocks were
made available to commercial seedsmen in 1972 and registered seed
(one generation removed from foundation seed) is available to
growers. In most cases better wilt resistance will be found in
plants from this "registered" seed than from standard commercial
seed. However, at least one seed company has selected for wilt
resistance in 'Jubilee'.

Old standard watermelon varieties and many new inbred and Fl varieties
have been evaluated since 1969. All Fl hybrids tested were very
susceptible to Fusarium wilt and planting in Florida is not recom-
mended. The hybrids included in tests were 'Top Yield', 'Sweetmeat',
'Triple Sweet Seedless', 'Tri X-313', 'Family Fun', 'Royal Charleston',
and 'Summer Festival'. Other varieties which lack wilt resistance
are 'Garrisonian', 'Florida Giant', 'Petite Sweet', 'Klondike Blue
Ribbon', and 'Peacock'. Marketable yield of 'Charleston Sweet' has
been low due to a large number of misshapen fruit. 'Louisiana
Queen', 'Summit', 'Calhoun Gray' and 'Smokylee' all have a high
level of resistance to Fusarium wilt. However, internal quality of
'Louisiana Queen' and 'Summit' is poor. Under optimum conditions

'Calhoun Gray' produces good quality fruit but moderate stress
conditions result in poor fruit quality. 'Smokylee' fruit have
excellent flesh quality including high sugar levels and fine
texture but white seed, susceptibility to sunburn, and difficulty
in determining proper harvest time have limited commercial plantings.
'Allsweet' has a level of wilt resistance comparable to that of
'Crimson Sweet' as well as excellent internal appearance and quality;
however, it matures too late for most commercial growers in Florida.
'Sweet Princess' fruit have a somewhat higher quality than 'Charleston
Gray' but yield is generally lower. Seed of 'Sweet Princess' are
quite small and it has been difficult to obtain an early, uniform
