  • Patent number: 9894867
    Abstract: A novel maize variety designated X00H389 and seed, plants and plant parts thereof are produced by crossing inbred maize varieties. Methods for producing a maize plant by crossing hybrid maize variety X00H389 with another maize plant are disclosed. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into X00H389 through backcross conversion and/or transformation, and to the maize seed, plant and plant part produced thereby. This invention relates to the maize variety X00H389, the seed, the plant produced from the seed, and variants, mutants, and minor modifications of maize variety X00H389. This invention further relates to methods for producing maize varieties derived from maize variety X00H389.

  • Patent number: 7294774
    Abstract: An inbred maize line, designated PHBAB, the seeds and plants of inbred maize line PHBAB, methods for producing a maize plant, either inbred or hybrid, produced by crossing the inbred maize line PHBAB with another maize plant, and seed and plants produced therefrom. The invention also relates to methods for producing a modified PHBAB maize plant that comprises in its genetic material one or more transgenes or backcross conversion genes and to the transgenic and backcross conversion maize plants produced by these methods. This invention also relates to methods for producing other inbred and hybrid maize lines derived from inbred maize line PHBAB and to the inbred and hybrid maize lines so produced.
