T HE knowledge that farm seeds maintain their viability over a long period of years may assist in solving the seed situation in years of drouth or of complete crop failure. Little is known of the viability of seeds after storage for several years under arid conditions. The data reported in this paper are from a study carried on with seeds stored for periods varying from ~ to ~ S years. The literature on storage of farm seeds was reviewed in a previous paper by the authors3 and will not be discussed here. Previous results have shown that seeds of wheat, oats, and barley exhibit a gradual decline in germination rate for a ~o-year period. At the end of this time their germination was approximately ~o% lower than when ~ year old. Germination of Rosen rye and Wisconsin Black soybeans decreased more rapidly. About ~o% of their original germination was lost in a S-year period. Germination of Black Amber sorghum dropped only 2% in 5 years. Yellow dent corn germinated well for the first S years but decreased rapidly after the sixth year. The results reported in this paper are a continuation of the previous work reported by the authors.
