  1. Inbred lines (315)
    1. Field corn (249): Yellow (191), White (24) y Special (34)
    2. Popcorn (15)
    3. Sweet corn (51): sweet su1 (38), improved sweet su1 se1 (5) y supersweet sh2 (8)
  2. Varieties
    1. Field corn (247): Populations (220): American (18), Spanish [Galician (93), rest of  Spain (37) and Spanish landraces (43)], Portuguese (18) and other origins (11); y Synthetics (27)
    2. Popcorn populations (27)
    3. Sweet corn (30): Populations (16) y Synthetics (14)

Maize Selection Programs

Some of the maize selection programs developed in the Misión Biológica de Galicia (CSIC) include:
  • Cycles of selection for yield improvement under corn borer attack
  • Cycles of selection for improved tolerance
  • Selection assisted by moleculars markers

Or genetic resources with modified morphological or biochemical features as:
  • Divergent cycles for the length of the internode basal ring
  • Divergent cycles for diferulate content in the pith
