The objective of this work was to evaluate the performance of intervarietal corn (Zea mays) hybrids with topcross crosses between landrace populations, and to confirm whether genetic dissimilarity between populations is correlated with the heterosis of the intervarietal hybrids in the field. Nine topcross hybrids were evaluated with their tester 'BRS Planalto', and the following landrace populations were used as parents: Argentino Branco, Dente de Ouro, Amarelão, Criolão, Caiano Rajado, Branco Oito Carreiras, Branco Roxo Índio, Cateto Branco, and Argentino Amarelo. The tester 'BRS Planalto' and the topcross hybrids Branco Oito Carreiras x 'BRS Planalto' and Criolão x 'BRS Planalto' showed higher per se potential for grain yield. The topcross hybrid Branco Oito Carreiras x 'BRS Planalto' showed a better performance for number of grains per row, grain weight, and ear diameter, whereas Criolão x 'BRS Planalto' displayed a better performance for the number of grains per row and ear length. Greater estimates of genetic distance did not necessarily result in greater heterosis values and were exclusively correlated with grain ear length. Therefore, it is not possible to predict the effects of high heterosis on grain yield, based on the genetic distance between the populations involved in the crosses. |

ABSTRACT: Until now there are few early soybean cultivars with adequated characteristics of productivity and plant height available to the economical soybean crop in the Cerrado Region. The yearly cultivars, besides to permit a better farm planning for planting and harvesting, thy also allow the use of no-tillage technique with two crop systems such as soybean before corn, sorghum or sunflower. BRS Rosa is a early cultivar (112 days of cicle) originated from the cross between FT Guaira X FT Estrela, resulting from a group work including Embrapa Cerrados, Embrapa Soja plus a significant finantial support of Cerrados Fundation. In the final testes to cultivars releasing, BRS Rosa was superior then the test cultivars such as FT 2000 and Emgopa 316. This cultivar is recommended to be cropped in Cerrado fertile soils of Goias State and Federal District. |
