The aim of the study was to determine specifically adapted sunflower hybrids based on 2007 testing network grain yield results, and also to show economic gain obtained by minimizing crossover interaction (COI) and utililising specific adaptation. Twenty commercial sunflower hybrids and 16 locations were included in testing. SREG (sites regression) analyses were done for the set of all tested locations, set of locations with aboveaverage mean yield and set of locations with below-average mean yield, to obtain GGL biplot with which-won-where patterns. When giving recommendations for growing sunflower hybrids, their adaptability examined in past years via GGL biplot methodology must be taken into account. Based on the results of GGL biplot comparative analyses, the specifically adapted hybrids identified were: Duško for Rimski Šančevi, Kikinda, Bačko Gradište, Bačka Topola set of above-average mean yield (better) locations, and for Neuzina, Neštin, Vršac set of below-average mean yield (poorer) locations; Bačvanin for Kula Vitovnica, Đurđin, Zaječar, Zrenjanin set of poorer locations; Branko for Kula location. Significant economic gain was obtained when cropping these three specifically adapted hybrids, in comparison to cropping those not adapted to particular locations.
