Even though maize ( Zea mays L.) seed has a relatively long storage life, improvement for this characteristic is desirable. My objective was to determine if the seed deterioration caused by an accelerated aging process could be reduced in maize populations using a recurrent selection breeding method. The C o , C 1 , C 2 , and C 3 cycles of two populations were evaluated. Evaluation for differences among cycles of selection was made on seed aged at 42 C and 100% R. H. for either 9 or 10 days. In one population, germination in the C 3 cycle was nearly double that of the C 0 cycle. Progress in the other population was less.
