Determination Of Yield And Yield Components Of Some Rapeseed (Canola) Varieties In Edirne Conditions

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.
