摘要： 通过对雄全同株类型薄皮甜瓜品种单性花转育的研究,表明单性花性状受显性基因控制,转育F1均表现为雌雄异花同株,回交后代出现雌雄异花同株和雄全同株的分离,经卡方检测,分离比例符合1:1.经杂交1代,回交2代的转育,后代果实性状逐渐趋于薄皮甜瓜品种,性状表现优良,通过自交,可选育出薄皮甜瓜单性花自交系,用于杂一代制种上.

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.
