Abstract
A phenotypic trait elicited by B chromosomes in maize (Zea mays L.) is reported. Plants with five or more B chromosomes often display an aberrant phenotype characterized by longitudinal white leaf stripes and/or narrow leaves. This phenotype intensifies with increasing numbers of B chromosomes and is the first case of a qualitative phenotypic trait attributable to B chromosomes reported in maize. Possible explanations for this striped leaf phenotype are considered.
