雌雄異花同株菠菜品系之選育

Abstract

菠菜花性分為雌株、純雄株、營養雄株及雌雄異花同株四種，一般未經選拔品種雌雄株比約1:1及少量雌雄異花同株。雌雄異花同株品系具有較雄株晚抽苔，產量高，有利於單株選拔留種並可以快速提高優良品種的雌性率等優點。 Extreme male, vegetative male, female and monoecious plants are four types of flower sex of spinaches. In an open pollinated cultivar, the ratio of male and female plants is in general 1:1, with a few monoecious plants. The advantages of a monoecious line include later bolting and higher yield as compared to male plants.
