Abstract
Abstract The intervarietal hybrid ‘UENF 506-11’ was derived from full-sib maize families in the 11th cycle of reciprocal recurrent selection. It produces a grain yield of 7.57 tons ha-1, and is recommended for cultivation in the North and Northwest regions of the Rio de Janeiro State.
Highlights
Maize (Zea mays L.) is a cereal of great economic and social importance, cultivated in almost all agricultural regions of the world and used in human and animal nutrition and, more recently, as a source of biofuel
Much of the yield potential of this crop in the country is the result of significant advances in breeding programs, which have progressively improved agronomic traits related to grain yield, disease resistance and adaptability to adverse conditions
The farmers grow open-pollinated varieties and hybrids developed for other regions of Brazil
