The scientific aims of our study were to determine the representativeness and discriminating ability of the test sites and to identify good test sites for selecting generally and specifically adapted sunflower hybrids. Correlations among test sites, revealed by biplot and with Spearman’s nonparametric rank correlation coefficients for each pair of test sites, were compared. Discriminating but nonrepresentative test sites in our study were represented by Aleksa Šantić ( °C average temperature, mm precipitation, and h of sunshine) and Rimski Šančevi ( °C average temperature, mm precipitation, and h of sunshine), based on a biplot analysis of the 2006 testing network. Sombor ( °C average temperature, mm precipitation, and h of sunshine) was also a discriminating but nonrepresentative test site, based on a biplot analysis of the 2007 testing network. A test site that was both discriminating and representative was Kikinda ( °C average temperature, mm precipitation, and h of sunshine), based on a 2007 biplot analysis. Sombor and Kikinda could be suitable test sites for selecting specifically and .
