Abstract Production of cool-season cereals is conducted in dry areas in our country. In these areas, the most important factors having effect on yield are total precipitation and distribution of precipitation in year. In certain years and regions, autumn drought happens because of this precipitation disorder. When this happens, deep sowing is necessary for seed to find moisture and germinate. The factor determining sowing depth is coleoptile length. In this study, ıt was aimed to determine coleptile length of some cultivars of barley (Kalaycı97, Çıldır02, İnce04, Özdemir05), milling wheat (Bezostaya1, Gerek79, Sönmez01, Müfitbey), durum wheat (Kunduru1149, Yelken2000, Dumlupınar, Ç1252), and triticale (Tatlıcak97, Presto, Karma2000, Alperbey). The seeds underwent surface sterilization were sown on blotting papers in sterilized petries. Coleoptile length of the seeds germinated at 20 °C in incubator was measured at the end of the 8th day. Coleoptile length differences for species and cultivars were found statistically significant (p<0,01). According to the results of the analysis, while the longest coleoptile was found in milling wheat (70 mm), the shortest coleoptile was found in triticale (53 mm) among the species. For cultivars, while Kunduru 1149 has the longest coleoptile with 80 mm, the shortest koleoptile was found in Tatlıcak97 (triticale cultivar) with 45 mm.
