We evaluated for agronomic performance and grain
quality under organic and conventional agriculture ten
open-pollinated populations, potentially valuable for
maize bread or bakery use (Table 1). Five of these
open-pollinated populations (Donostia, Meiro, Rebordanes,
Sarreaus, and Tuy) have been improved for
grain yield or flour yield during one or three cycles.
The breeding program for Donostia was carried out in
the experimental field of NEIKER (A´ lava) and
consisted on evaluating 100 S1 families and recombining
the 20 S1 families with the higher ability for
making ‘‘talo’’, a kind of maize bread. One cycle of
selection was carried out. The breeding program for
Meiro, Rebordanes and Sarreaus was carried out in the
