Six generations of six families were generated in 2011 and 2012. These genotypes were tested in a field experiment, conducted in Dardanos Research and Application Center, Canakkale, Turkey, in 2013. Data were collected on oil content and grain yield per plant and then analyzed by using Generation Mean Analysis method to determine the appropriate families for simultanous selection studies. We also calculated genetic effect estimations for these traits in the investigated genotypes. Results showed that there were significant differences among the families and generations for oil content and grain yield. The variation in oil content in the families was mainly controlled by additive gene actions. Simultaneous selection did not seem feasible in the tested families, though there was a good chance for considerable enhancement in some genotypes if the investigated traits were taken into account singlehandedly. Three families (A680x-IHO, IHOxB73 and IHOxHYA) showed potential for selection to enhance oil content, while two others (IHOxMo17 and Mo17xIHO) were promising for grain yield. Estimated genetic gains were in the range of 0.4% to 4.1% per cycle for oil content, and 17.7 g to 60.7 g per cycle for grain yield.eninfo:eu-repo/semantics/closedAccessadditive gene actiondominance gene actionselection responseZea maysA preliminary study for determination of the possibility of simultaneous selection for oil content and grain yield in maizeArticle601Q3WOS:0003780801000042-s2.0-84964901181Q3
