Selection of Successive Progean Mutants by Space Flight in Purple Alfalfa

As a new physical inducement, space inducement, has been used in many kinds of plants materials. On the basis of the selection of the first generation alfalfa plants, further selection of several mutants with promising agronomic traits have been used in plant breeding programs. To understand the mutagenic effects of space flight on alfalfa seeds, the genomic changes in consecutive generation plants developed from these seeds, the mutation in morphological traits and genomic polymorphism on plants developed from these seeds and their selected progenies were investigated in this study.
