GENERAL INTRODUCTION
LIST OF FIGURES
Figure 1. Cultivar Charleston Gray, released in 1954 by C.F. Andrus. Resistant to Fusarium wilt,
anthracnose, and sunburn..............................................................................................................17
Figure 2. Cultivar Allsweet, released in 1970 by C.V. Hall. Resistance similar to 'Charleston
Gray', but higher fruit quality........................................................................................................18
Figure 3. Watermelon seeds covered by an additional layer of fleshy pericarp in Egusi cultivars,
as induced by the eg gene..............................................................................................................19
Figure 4. Watermelon seeds size: 1 = tomato (watermelon seeds of the size of tomato seeds), LL
ss tsts or ll ss tsts; 2 = small (or short) (~5 mm), LL ss or ll ss; 3 = medium (~7 mm),
LL SS; and 4 = large (or long) (~10 mm), ll SS. ..........................................................................20
REVIEW OF INHERITANCE OF RIND PATTERN IN WATERMELON
Figure 1. Cultivars Thurmond Gray and California Klondike used by Porter in 1937 in the first
reported study of the inheritance of dark vs. light green rind colors in watermelon................29
Figure 2. Cultivars Japan 6 and China 23 used by Weetman in 1937 to determine the inheritance
of the lined and netted rind patterns (p and P alleles, respectively) in watermelon..................30
Figure 3. Cultivars Long Iowa Belle and Round Iowa Belle used by Weetman in 1937 to
determine the inheritance of the mottled rind pattern (a.k.a. Iowa Belle or IB-type) and
regulated by the m gene in watermelon........................................................................................31
Figure 4. Cultivars Crimson Sweet (fruit on the left) and China 23 (fruit on the right) showing a
similar netted phenotype. 'Crimson Sweet, pending verification of the inheritance of
the netted phenotype, could be the new type line in substitution of 'China 23' for future
genetic studies and breeding work................................................................................................32
