摘要
An intelligent genetic breeding and seed production system for crop cross breeding and hybrid seed production, and an application thereof. The system comprises a GAT system carrier. The carrier comprises five functional element expression cassettes: a plant male fertility restoration genetic element expression cassette, used for restoring the male fertility of a recessive genic male sterile mutant; a plant pollen abortion genetic element expression cassette, used for clearing GAT containing pollen and maintaining a heterozygous state or a hemizygous state of a GAT maintainer line; a chemical herbicide positive selection expression cassette, used for gene transformation and impurity removal and purification for the GAT maintainer line; a chemical herbicide negative selection expression cassette, used for clearing pollen and seed escape of a herbicide-sensitive GAT maintainer line and impurity removal and purification for a GAT sterile line; and a seed screening element expression cassette, used for mechanical sorting of seeds. The system can be used for cross breeding and hybrid seed production of plate recessive genic male sterile materials, thereby obtaining new varieties of plants having high quality, high yield, wide adaptability and high resistance, and seeds thereof.
