title: Corn Seeds Affected by Heavy Cosmic Ray Particles.
abstract: Corn seeds of a special genetic stock were recovered from two satellite flights and the plants grown from them were examined for abnor malities. Some evidence for a slight increase in chromosomal deletions was observed, which was predicted from the flux of heavy cosmic ray primary particles. Nothing unexpected was observed.
