Özet:

Aim of this study is determine to fresh ear yield and quality characters of sweet corn varieties which Vega, Challenger, Sentinel, HYRIX 39, and HYRIX 53 in two location in Turkey. The research was conducted on randomised blocks design  with four replication in Bafra and Tekkekoy location. The experiment was caried out evaluate the yield and quality performance of some sweet corn genotypes as well as demonstrate unfamiliar supersweet corn concept in Turkey. In the research were obserwed some yield component and quality characters such as flowering time, plant length, first cob length, grain yield, cob diameter, cob length, number of rows in the cob, amount of grains in row, number of marketable cobs per plant, wet cob harvest time, wet cob yield, grain cob ratio, grain moisture, dry grain yield. It was found that sweet corn genotype are significantly different in terms of yield and quality characteristics. The highest wet cob yield was 24.238 t ha-1 in Hybrix 39 super sweet.  Super sweet corn has an important potential in sweet corn cultivation due to high yield of dry grains and its high maintenance rate of sugar raito in the long term after harvesting. Statistical analysis showed that the effect of genotype and the environment, as well as their interactions,  had a significant impact on the yield of sweet corn hybrids. The presented results have demonstrated the poerformance of some sweet corn in Turkey. This work is intended to inspire similar studies using other sweet corn varieties and also to encourage the wide-scale production sweet corn in Turkey.
