Abstract: A novel maize variety designated X90T989 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 X90T989 with another maize plant are disclosed. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into X90T989 through backcrossing or genetic transformation, and to the maize seed, plant and plant part produced thereby are described. Maize variety X90T989, the seed, the plant produced from the seed, and variants, mutants, and minor modifications of maize variety X90T989 are provided. Methods for producing maize varieties derived from maize variety X90T989 and methods of using maize variety X90T989 are disclosed.

Abstract: A novel maize variety designated 4ZZIX1570 and seed, plants and plant parts thereof are provided. Methods for producing a maize plant comprise crossing maize variety 4ZZIX1570 with another maize plant are provided. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into 4ZZIX1570 through backcross conversion and/or transformation, and to the maize seed, plant and plant part produced thereby are provided. Hybrid maize seed, plants or plant parts are produced by crossing the variety 4ZZIX1570 or a locus conversion of 4ZZIX1570 with another maize variety.
