Miniature germ was reported by J. B. Wentz (J. Hered. 15:269-272). This stock was never included in the Coop. A similar phenotype was found as a mutant in one of the breeding cultures and segregation indicated a single factor. Seed size is essentially normal but germ size is reduced to one-fourth or one-third of normal. In the sand bench mg seedlings are somewhat delayed in emergence. Under field conditions mg plants attain normal size and are fully viable. No linkage data are available but this should prove to be a useful seed trait.
