Estudo da estabilidade fenotípica de nove genótipos de soja (Glycine max L. Merril) pelo uso de regressão linear segmentada
Palabras clave:
estabilidade fenotípica, genótipos de soja, regressão linear, interação genótipo-ambiente, ambientes favoráveisResumen
The data from nine varieties tested at forty-three environments indicated that the use of piecewise linear regression allowed identification of varieties with diffe- rent performances over unfavorable and favorable environments. However, it was not effective to reduce the deviation from regression, as compared to the use of simple linear regression.
