In this study, 19 genotypes in 2012 and 27 genotypes in 2013 were used as research materials. The experiments were conducted in the trial field of GAP International Agricultural Research and Training Center in Diyarbakir with randomized complete block design with three replicates in 2012–2013. The findings of the experiment in 2012 were as follows: plant height (245.0–343.8 cm), first ear height (89.5–144.5 cm), tasseling period (72.7–80.3 day), grain/ear ratio (84.7–88.7%), 1000 grain weight (283.2–365.0 g), moisture (10.6–13.1%), hectoliter weight (76.93–81.43 kg), crude oil ratio (3.07–4.17%), crude protein ratio (9.03–11.23%), starch ratio (70.27–72.63%), grain yield (936.1–1307.7 kg/da). In 2013 the yield parameters were as follows: plant height (260.7–363.2 cm), first ear height (96.5–169.0 cm), tasseling period (63.0–74.3 day), grain/ear (78.6– 91.4%), 1000 grain weight (247.0–395.0 g), moisture (8.10–11.8%) and grain yield (685.4–1318.9 kg/da). As a result; P31G98, DKC6589, ADA 523, ADA-9.7, SASA-95, SASA-84, SASA-71, SASA-87, ADA-11.19, SASA-75, ADA-11.17, ADA-11.20, ADA-11.7, SASA-96 genotypes gave relatively higher yields as main crop production in Diyarbakir conditions.
