Description
Summary:The objective of this study was to analyze the adaptability and the stability in apomictic genotypes of the genus Paspalum across the main characters of forage interest evaluated in different years and locations. The experiment was conducted in the years 2010 and 2011 in the municipalities of Eldorado do Sul and Augusto Pestana, RS, Brazil, in a randomized complete block design with three replications. Analyses of adaptability and stability were calculated by the Traditional and the Eberhart and Russel method. The genotypes of P. guenoarum Baio anda Azulão shows high biomass production but adapted to favorable environments and reduced stability. The genotypes of P. lepton 28C show the total dry mass specific adaptability to unfavorable environment and in the dry leaf adaptability with stability
