ABSTRACT

This research was carried out to determine of yield and yield components of some rapeseed (Brasicca napus L.) varieties in Trakya Agricultural Research Institute-Edirne conditions.

The experiments were established in randomized complete block design with 9 varieties in four replications. The research lasted for three growing seasons from 2003 to 2006. As a material Egc-102, Embleme, Elvis, Likord, Licrown, Bristol, Eldo, Jura ve Capitol 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, 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 to three-years results of this research in Edirne conditions, it has been found statistically significant (%0.01) seed yield differences among 9 varieties. First flowering date 4-14 April, physiological maturity date 7-9 June, plant height 125 cm-150 cm, capsule number per plant 119-129, seed number per capsule 22-26, capsule cracking 1-10%, and seed yield per hectare 2023-2847 kg were found among nine rapeseed varieties.

Key words: Rapeseed (Brasicca napus L.), variety, yield, oil, and adaptation.
