The objective of this study was to directly compare total biomass yields among a diverse group of maize hybrids where shoot maturation was delayed in two ways: either by crossing genetically diverse temperate-adapted inbreds with photoperiod-sensitive inbreds of largely tropical origin, or by overexpression of the maize Glossy15 gene in different temperate-adapted hybrids. Biomass and nitrogen accumulation in stover and grain were evaluated for these genotypes in field trials on nitrogen-limiting (no supplemental fertilizer) or nitrogen-sufficient soils (200 kg N fertilizer per hectare). The results obtained demonstrate that use of either photoperiod-sensitivity genes or Glossy15 can variably delay shoot maturation and reduce harvest index in a wide diversity of temperate-adapted backgrounds.
