Selection of variety with high potential yield and adaptability is one of the most effective
ways to increase corn production. This research was carried out according to the
randomized complete blocks experimental design with 10 corn genotypes (five sweet corn,
four flint corn, and one dent corn) in 2022 and 2023 years under Erzurum conditions. The
differences among the genotypes were significant in terms of all the characteristics
investigated, except plant number per hectare. As average of years, the days to silking of
the genotypes was between 63.3-78.0 days, days to maturity for fresh ear harvest 98.2-
110.0 days, plant number per hectare 86969-89585, ear number per plant 1.10-1.83,
chlorophyll value (SPAD unit) 45.2-55.6, maximum quantum yield at PSII (Fv/Fm) 0.716-
0.784, green mass yield 75337-108544 kg/ha, kernel number per ear 231.9-692.0, fresh ear
yield 15312-25465 kg/ha, grain protein content 10.4-16.2 %. The highest green mass yield
was obtained from Simpatico-KWS, the highest fresh ear yield from Khan F1, the highest
kernel protein content from Challenger F1 and Karaçam genotypes. Only silage or corn for
fresh consumption can be produced in Erzurum Plain conditions due to the short vegetation
period and low average temperatures. Crow damage during the germination-emergence
period and the first frost in autumn may a risk for corn production.
