¹ Trakya Tarımsal Araştırma Enstitüsü, Edirne DOI : 10.21566/tarbitderg.281882 - This research was carried out to determine of yield and yield components of some advanced rapeseed (Brasicca napus L.) varieties in Trakya Agricultural Research Institute-Edirne conditions.The experiments were established in randomized complete block design with 8 varieties in four replications. The research lasted for two growing seasons from 2012 to 2014. As a material totally 8 genotypes` 4 advanced lines` TK- 05-10, TK-05-12, TK-05-14, TK-05-20 and 4 certified standard varieties` Süzer, Excalibur, Elvis, NK-Petrol winter rapeseed varieties are used in the experiment. Observations and evaluations were made for grain yield/ha, seed oil content %, oil yield/ha, 1000 seed weight, full plant emerge date, cold tolerance, plant height, branch number, capsule number in per plant, seed number per capsule, capsule crack %, first flowering date, plant lodging, and percent seed moisture in harvest. According two growing season results of this research in Edirne conditions, it has been found statistically significant (0.01%) seed yield differences among advanced lines and certified varieties. Whole flowering date 9 to 17 April, physiological maturity date 3 to 10 June, plant height 170 to 190 cm, capsule number per plant 126 to 164, seed number per capsule 22-26, pods cracking 0 to 5%, and seed yield per hectare 2860 to 3503 kg were changed among eight rapeseed advanced lines and varieties.
