Abstract: A method for enhancing induction efficiency of corn haploid is disclosed, which belongs to the technical field of genetics. In the method disclosed by the disclosure, the tropical induction line is used as a female parent, the temperate induction line is used as a male parent, hybrid seeds among the temperate and tropical induction lines are generated by hybridizing and assembling, the hybrid vigor among the temperate and tropical induction is used for improving the agronomy and yield traits of the conventional induction line, so that the requirements of the corn haploid induction line as the male parent on plant height, pollen quantity, fertility period and the like are met, which has important significance for large-scale popularization and application of the corn double haploid (DH) technology.

Abstract: A high-power-microscope-assisted identification method of maize haploid plants is provided, the method is implemented by a device including a high power microscope, a main frame disposed on an objective table of the high power microscope and a computer and includes four procedures of sample information input, automatic testing of a batch of samples, automatic analysis and comparison, and automatic generation of data results. Vertical sliding grooves are symmetrically formed in the main frame, and a vertical supporting plate is disposed at an upper end of the main frame. Horizontal sliding grooves are symmetrically formed in the vertical supporting plate, and a horizontal supporting plate is disposed on the vertical supporting plate.
