Abstract: We have completed the first cycle of RRS in the tropical and subtropical yellow gene pools. The best S2 lines were increased for seed distribution. In pool 25 and 26, to determine combining ability of the S2 lines selected by RRS, 10 best S2 were chosen to make the testcrosses with two inbred lines and the opposite pool. A half of the highland gene pools were planted and advanced to S1. Enhancement of donor germplasm sources and their testcross evaluations were performed for tropical and subtropical yellow flint and dent pools. Yellow flint and dent donor sources were developed for tropical gene pools: 17, 18, 25, and 26. Latin American germplasm regeneration project has continued, receiving the regenerated accessions from Mexico, Venezuela, Ecuador, and Peru. CIMMYT regeneration was focused on Chile, Argentine, and Brazilian accessions. Accessions evaluation was conducted with the accessions from Argentine. The regeneration and germplasm evaluation was slightly less than what was desired. Seed distribution was met as requested. The number of seed packets prepared for distribution was less as compared to those in the previous years.
