New maize germplasm introductions in Brazil

Através de uma rede nacional foram avaliados 51 ensaios, visando escolher populações de milho do CIMMYT com potencial no Brasil. Os resultados obtidos mostraram que os materiais pool 21, pool 22, pool 25, pool 26, Suwan DMR, Tuxpeno-1, Mezcla Tropical Blanco, Blanco Cristalino-1, Ant. x Ver. 181, Mezcla Amarilla, Amarillo Cristalino, Amarillo Dentado, Amarillo Subtropical, Antigua x Rep. Dominicana e Eto x Illinois foram os que mais se destacaram nos ensaios. Assim, estão disponíveis, aos programas de milho do Brasil, estas novas populações de milho, de porte baixo e ciclo precoce a intermediário. Na indicação dos "pools" e "Suwan DMR" considerou-se somente a produtividade.In 1976 many sources of new germplasm considered to have potential in Brazil were selected and introduced from CIMMYT. This material was evaluated in 51 experiments throughout Brazil in a network of national trials to determine its genetic potential. On the basis of these results, the following germplasm have potential in Brazil: Pool 21, 22, 25 and 26, Suwan DMR, Tuxpeno 1, Mezcla Tropical Blanco, Blanco Cristalino 1, Antigua x Vera Cruz 181, Mezcla Amarilla, Amarillo Cristalino, Amarillo Dentado and Subtropical, Antigua x Rep. Dominicana and Eto x Illinois. They were selected based upon high mean yield, earliness and low plant and ear height, except for Pools and Suwan DMA which were only considered for high mean yield
