| Abstract | ||
| In order to compare the yield, yield components, oil percent and vegetative characters of canola cultivars in Gonbad, 23 genotypes of spring rapeseed were planted at Agricultural Research Station of Gonbad during 2000-2002. The experiment was a randomized complete block design with 4 replications. The results of combined analysis showed that effect of year, cultivar and interaction between year and cultivar were significant on the number of days from emergence to flowering, physiological maturity, duration of flowering and seed yield at the 1% level. Cultivars Hyola 308 and Syn-3 had the lowest and Dakini had the highest number of days from emergence to flowering and physiological maturity. The interaction was significant because of different temperature in two years of the experiment. The effect of cultivar was significant on number of pods per plant and number of seeds per pod at the 1% level. Hyola 401 Hybrid produced the highest number of pods per plant and Profit and Rafaela cultivars produced the highest number of seeds per pod. The effect of year was significant on 1000 seed weight at the 1% level. Year did not significiant1y affect oil percent, whereas cultivars differed significantly in oil yield. Profit, Option 500 and Hyola 401 had the highest oil percent. The mean of seed yield in the second year of experiment was more than that of the first year. The seed yield in the second year and first year of the experiment were 3658 and 3015 kgha-1, respectively. Hyola 401 hybrid produced the highest seed yield (4479 kgha-1) and oil yield (2042 kgha-1). | ||
