A Apetalous Gynoecious Mutant in Watermelon
A gynoecious (gy) mutant was previously described in watermelon (Jiang and Lin, 2007; Fig. 1). This original gy mutant will eventually produce some perfect flowers which will allow the genotype to be selfed and maintained. A apetalous gynoecious mutant was observed from gynoecious line ‘Mi Guo’ grown in the winter nurseries in Sanya, Hainan in […]
A New Dwarf Mutant dw-4 in Watermelon
A spontaneous dwarf mutant was discovered from inbred watermelon line ‘5-6y’. Genetic study showed that the dwarf mutant is genetically stable and the dwarf trait is inherited as a single recessive gene. Allelism test showed that the new dwarf gene is not allelic to the two known dwarf genes dw-1 and dw 2. The allelism […]
Green-Fleshed Watermelon Contains Chlorophyll
Many popular and technical reports on watermelon flesh colors ignore green, an uncommon color. The earliest report of this color mutant that we were able to find dates back more than one hundred years. In this report, inheritance of pink-fleshed vs. green-fleshed genes in watermelon was explored and resulted in fruit intermediate in character, the […]

2007 Gene List for Watermelon
by Todd C. Wehner Department of Horticultural Science, North Carolina State University, Raleigh, NC 27695-7609 Introduction Watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai) is a major cucurbit crop that accounts for 6.8% of the world area devoted to vegetable crops (FAO, 2002). Watermelon is grown for its fleshy, juicy, and sweet fruit. Mostly eaten fresh, they […]
