Estimating the term…
A novel maize variety designated X03P558 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 X03P558 with another maize plant are disclosed. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into X03P558 through backcrossing or genetic transformation, and to the maize seed, plant and plant part produced thereby are described. Maize variety X03P558, the seed, the plant produced from the seed, and variants, mutants, and minor modifications of maize variety X03P558 are provided. Methods for producing maize varieties derived from maize variety X03P558 and methods of using maize variety X03P558 are disclosed.
A seed of hybrid maize variety X03P558, representative seed produced by crossing a first plant of variety PH48AR with a second plant of variety PH48B8, wherein representative seed of the varieties PH48AR and PH48B8 have been deposited under NCMA Accession Numbers 202004028 and 202004029, respectively.
A seed of hybrid maize variety X03P558 further comprising a single locus conversion, wherein a plant grown from the seed comprises a trait conferred by the single locus conversion, and wherein the seed is produced by crossing a first plant of variety PH48AR with a second plant of variety PH48B8, wherein the first plant, the second plant or both further comprise the single locus conversion, and wherein representative seed of the varieties PH48AR and PH48B8 without the locus conversion have been deposited under NCMA Accession Numbers 202004028 and 202004029, respectively, and wherein the seed produces a plant having otherwise all the physiological and morphological characteristics of maize variety X03P558 when grown under the same environmental conditions.
A method for producing a hybrid maize variety X03P558 seed further comprising a locus conversion, the method comprising crossing a first plant of variety PH48AR with a second plant of variety PH48B8, representative seed of the varieties PH48AR and PH48B8 having been deposited under NCMA Accession Numbers 202004028 and 202004029, respectively, wherein at least one of the varieties PH48AR and PH48B8 further comprises the locus conversion.
