TEAF rust of corn, caused by Puccinia sorghi Schw., has -" developed in epiphytotic proportions in areas of the corn belt of the United States in some years. Nevertheless, total losses due to this disease are believed to be small. Conceivably this disease could become more important since the various rusts on corn have caused substantial yield reductions in other regions of the world. Inheritance studies of all known sources of rust resistance will be helpful to the plant breeder in the production of disease-resistant hybrids. Such studies are also necessary to develop an adequate understanding of the genetics of host-parasite systems. Published reports concerning inheritance of rust resistance in corn have dealt almost entirely with resistance controlled by single dominant genes. Rust resistance controlled by recessive factors is only briefly mentioned in the literature. This paper reports studies on the inheritance of resistance in two inbred lines where resistance is conditioned by recessive genes.
