THE production of heritable changes in the maize genome is an important part of maize genetic research. Chromosome breaks, deficiencies, duplications, translocations, inversions, gene mutations, and transposon insertions all have their place. There are unique and efficient ways to produce each, as described in Stadler and Roman (1948), Sax (1957), Nuffer (1957), Sparrow (1961), and McClintock (1951). Special attention should be given Stadler’s (1946) descriptions of methods of studying mutation; the implications of seed vs. pollen treatment in relation to the ontogeny of the germ cells are discussed by several authors (Coe and Neuffer 1978; Johri and Coe 1983; Coe et al. 1988). Reviews of mutagenic agents, techniques, applications, and consequences are presented in Bird and Neuffer (1985) and Neuffer and Chang (1989).
