Initial Exploration about Creation of New Tomato Male Sterile Line and Its Seed Production Technology

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.
