Combining ability among apomictic and sexual parents of Urochloa humidicola [PDF]

Grass and Forage Science, 2019
AbstractThe diallel cross constitutes an informative genetic design for choosing genitors and crosses in breeding programmes since it provides estimates of general (GCA) and specific (SCA) combining abilities. Because the breeding programme for Urochloa humidicola ([Rendle] Morrone & Zuloaga; syn. Brachiaria humidicola [Rendle] Schweick) at Embrapa

Adaptation, calibration, and validation of the agro-ecological zone model for Urochloa humidicola pastures [PDF]

Revista Ciência Agronômica, 2023
The agro-ecological zone model (AZM-FAO) is used to describe agricultural scenarios and the impact of climate risk on crops and, when adapted, can be used to simulate the yield of forage species under adverse conditions.
