Deletion Mutagenesis and Identification of Causative Mutations in Maize.

Abstract excerpt

We describe a method for gamma-irradiation of mature maize seeds to generate mutants with opaque endosperm and reduced kernel fill phenotypes. We also describe methods for mapping mutants and identifying causal gene mutations. Using this method, a population of 1788M2 families and 47 Mo17 × F2s showing stable, segregating, and viable kernel phenotypes was developed. For molecular characterization of the mutants,...
