Abstract:
    The invention relates to a method for breeding corn cross system. Wherein, it comprises (1), selecting at least 20 SSR primers with polymorphism on the basic material S0 generation; each isopathic couple of chromosomes has at least two SSR primers whose genetic distance is at least 50cm; (2), using at least six couples of SSR primers, selecting single one of S1 generation that purified combined on said six SSR primers, while SSR primers are at least at six couples of isopathic chromosomes; (3), using at least 14 SSR primers expect from the ones in step (20, selecting S2 generation, to obtain the S2 single one purified combined on said 14 SSR primers, as the core cross system.
