Some of the salient findings of genetic studies on maize carried out over a period of twenty-two years since 1939 are herein presented. This period is divisible into two. In the first fourteen years, genic analyses of 27 mutant characters were mainly made at the Hokkaido University. In this period, 55 genes were analyzed, and linkage relationships of 39 out of these 55 were ascertained. Mapping of 18 of these loci on the maize chromosome map established was possible (Table 1). In the subsequent eight years, 1953 to the current year, researches were on the characteristics of oriental maize in relation to the expression of heterosis. This work was done at the National Institute of Agricultural Sciences, Hiratsuka.
