| 摘 要： | 以长柱头型番茄雄性不育系TL431为母本，以花药闭合型番茄雄性不育系T69为父本配制杂交组合，对杂交后代进行6代系谱选择，创造出花药闭合且柱头伸出药筒的新型番茄雄性不育系（PSL）N431-69，该雄性不育系具有柱头外露容易授粉、不育度达100%、能够自交保存等优点。进行番茄杂交制种不但省时省力，而且能够保证杂交种子纯度。

| Abstract: | A new tomato(Lycopersicon esculentum Mill.)male sterile line was created by crossing tomato positional male sterile line TL431 as female parent and indehiscent anther male sterile line T69 as male parent.The hybrid progeny was selected by mass and pedigree selecting method of 6 generations and created a new tomato male sterile line(PSL)which have long stigma and indehiscent anther.This new tomato male sterile line has lots of virtue,such as:easy to accept pollen,sterility degree to be 100% and to be maintained easily by artificial pollination,etc.This new tomato seed production technology can not only save time and energy,but also guarantee the purity of hybrid seed. |
