Discovery and Genetic Study of New Male Sterile in Maize

In this research,we obtained a great deal of sterile plants from the offspring of transgenic Bt maize by agrobacterium.Obtained stable male sterile inbreds when this materials were pollinated by acceptor inbred lines of 18 red.The sterile stability was observed in 2 locations,for 2 years and 3 generations.In order to analyse the kind of male sterile,many normal inbred lines were used to cross with this mutant.The main results are as the follow: the male sterile mutant is stable,inheritable in different years and different locations.It attributes to cytoplasmic male sterility.The appearance of male sterile mutant is the conclusion of somaclona variation.
