Improvement for Accelerated Aging Response of Seed in Maize Populations1

  1. Gene E. Scott2

Abstract

Abstract

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 Co, C1, C2, and C3 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 C3 cycle was nearly double that of the C0 cycle. Progress in the other population was less.
