Inheritance and Morphology of Two Dwarf Mutants in Watermelon1

Abstract: An inheritance study of 2 dwarf mutants in watermelon showed that dwarfness in each form is due to single, non-allelic, recessive genes designated dw-1 and dw-2. Dwarfness in dw-1 and dw-2 plants was primarily attributed to reduced length of internodes, but there was also some reduction in the number of internodes in the dwarfs compared to the normal plants. The shorter internodes in dw-1 dwarfs were due to both fewer and shorter cells than in the internodes of vine forms. In the dw-2 dwarf most of the reducti… Show more

“…Three strains of watermelon were used in this study: WB-2, 'Sugar Baby', and dwarf 'Sugar Baby' [(SB(<7w-2)]. WB-2 is an inbred monogenic recessive dwarf, conditioned by the dw-2 gene (13). SB (dw-2) was obtained by backcrossing WB-2 to 'Sugar Baby' and using 'Sugar Baby' as the recurrent parent for 4 successive generations.…”

“…Crops with dwarf traits, including short internodes, short main stem length and bush-type growth habits, have been reported in watermelons (Citrullus lanatus L.), such as dw-1, dw-1 s, dw-2, dw-3, and dw-4 (Liu and Loy 1972;Huang 1995;Yang 2010). The rst dwarf watermelon was a mutation from the standard vining watermelon inbred line WB-2, which contained a recessive dw-1 gene and exhibited short internodes resulting from abnormal internode cells (Mohr 1956).…”
