Inheritance and Morphological Traits of a Double Recessive Dwarf in Watermelon, Citrullus lanatus (Thunb.) Mansf.1

Year: 1975

Type: article

Abstract: When 2 mutant dwarf watermelons were crossed, the F 1 was of normal vine type, indicating that these genes for dwarfness were non-allelic. The F 2 segregated 9:3:3:1, with the double recessive a plant form hitherto unreported. The designated genotype of this digenic recessive dwarf is dw 1 dw 1 dw 2 dw 2 . It has much shorter internodes than either parent, the crown branching characteristic of 1 parent and the naked bud characteristic of the other, and it was later in maturity than either parent. Breeding lines derived from double recessive plants show promise of horticultural value as cultivars for the home garden and intensive commercial culture with the possibility of a mechanized harvest.
