Abstract:
It was studied to transfer the character of single-sex flower to orientaLmelon with double-sex flower through crossing.T he study showed that the character of single-sex flower was controlled by dominant gene.F1hybrid of crossing expressed single-female flower and single-male flower.Some of hybrids of crossing a-gain with orientaLmelon expressed single-female flower and single-male flower, while others expressed single-male flower and double-sex flower.T hese hybrids had a 1B1 parting proportion in two different kinds by V2-measure.The fruit of the hybrid that was gained through crossing once and recrossing twice was increasingly similar to orientaLmelon and had improved qualities.T he hybrid can be cultivated to become a crossing-self sys-tem with the charactersof single-sex flower and orientaLmelon, which wilLbe used as a mother to make crossing seeds.
