- Abstract
The objective of this work was to study different adaptability and stability methodologies and verify that the joint use of these methodologies can provide greater reliability in the selection of Pennisetum sp. clones to the forage yield. It was evaluated eight Pennisetum spp. clones (Taiwan A-146 2.37, Taiwan A-146 2.27, Taiwan-146 2,114, Merker Mexico MX 6.31, Mott, HV-241, and 'Elephante B' and IRI-381). The methods used to study the adaptability and stability were Eberhart and Russell, Wricke and Lin and Binns. The HV-241 clone, despite its adaptability to favorable environments, showed the lowest yield stability. The best performing were Taiwan A-146 2.37 and 'Elefante B' genotype, however, the former is suitable for favorable environments and the latter to unfavorable environments. The evaluation of Pennisetum spp. clones through different adaptability and stability methodologies to the forage yield allowed for greater characterization of productive performance of the clones and can provide greater reliability to the selection.
