Abstract
This study was carried out to determine the yield, yield components and
oil ratio of some canola cultivars under semi-arid conditions. Trials were
established in the trial field of Department of Field Crops, Faculty of
Agriculture, Harran University in randomized complete blocks trial design as 3
replications. In the experiment, Licord, Es-Astrid, Embleme, Eldo, Elvis,
EGC-102, Licrown, Bristol, Es-Nectas and Es-Hydromel winter cultivars were
used. In the results of study; the highest seed yield was obtained from Elvis
cultivar (2270.3 and 2081.7 kg ha-1) in two years of the experiment.
According to the results of two years between the cultivars; the plant height
was from 125.13 to 146.57 cm, number of branches 3.83-5.76 (per plant-1),
number of pods 115.20-194.73 (per plant-1), number of seeds
21.00-27.30 (per pod-1), 1000 seed weight 3.07-3.78 g, oil ratio
27.16-44.96%, number of flowering days 157-169, and the number of maturation
days was from 198 to 214. Because of seed yield and especially oil ratio were
observed very high, Elvis variety can be recommended in conditions of less
rainfall areas with limited irrigation facilities.
