maize mutant phenotypes

iojap iojap striping: ij1 converged to K55 inbred, showing loss of margin tissue (narrow, midribs) and diminished plant (Coe photo)

iojap Photo of sr3-N504A, (ij*-N504A) iojap mutant seedlings from segregating F2 progeny, with normals removed, showing broad sectors of white tissue, especially on leaf blade

iojap An iojap, ij*-N1143C, mutant seedling (left) showing broad white longitudinal stripes on leaves. The smaller green stripes are often lighter because they are the expression of single layers of cell.

iojap iojap striping: pale green iojap plant showing occasional dark green sectors; Extreme expression under cool growing conditions

iojap Two iojap, ij*-N1143C, mutant seedlings; one on left showing broad white stripes on leaf borders and the other is an almost white variant.

iojap First 2 leaves of a white striped ij2-N8 F2 mutant seedling showing broad white stripes on margins with much narrower stripes in the mid-section and tiny green stripes in the white area. Also note light marginal stripes on the 1st leaf of the seedling inadvertently selected as normal suggesting that it may actually be heterozygous and that this mutant is semi-dominant.
