Interpretive Summary:

Technical Abstract: Association of a cDNA sequence with a phenotype provides a powerful tool to enhance our understanding of biochemical pathways, regulatory sequences, and quantitative trait expression. More than a thousand maize mutants affecting seedling, whole plant, and kernel characteristics are available. As a first step toward defining corresponding cDNAs and phenotypes, 58 mutants have been placed relative to RFLP markers on chromosome 1S. There are 4 dominant and 54 recessive mutants of which 34 are seedling/plant and 24 are kernel phenotypes. Phenotypes include viviparous, high chlorophyll fluorescence, lethal leaf spot, pale green, defective crown, luteus, japonica, necrotic, tiny plant, bleached, virescent, white, striate, indeterminate, rough sheath, wide stripe, compact plant, zebra, zygotic lethal, and opaque, brown collapsed, defective, etched, pitted, or small kernel types. Initial bin placements were made relative to UMC Core Markers after which additional markers within bins were used on the remaining maize chromosomes.
