Abiotic stress factors such as drought and high temperature cause large yield losses in corn cultivated fields in the world and in Turkey. In this study; effects of water stress on some maize genotypes on the differences between tassel and silking flowering time, and anthesis-silking interval. The study was conducted in the southern Turkey's Harran Plain climat e and soil conditions during the main crop corn growing season of 2015 and 2016. Three hybrid maize cultivars and 17 maize pure lines were used in the study. The study was conducted according to split plots experimental design with three replicates. Main plots were water deficit (100% control and 50%) and sub plots were maize genotypes. The difference between, tassel flowering time, silking flowering time and anthesis-silking interval (ASI) were examined. According to results, high temperatures and applied water stress affected plants negatively in both trial years. Compared to 100% (control), tassel flowering and Silking flowering time delayed while anthesis-silking interval (ASI) increased under water deficit and high temperature stress conditions.
