| Abstract | ||
| Â Seed and oil yield, yield components, agronomic traits and oil percentage of 18 canola spring genotypes were evaluated in a two year experiment with different climate conditions at Agricultural Research Station of Gonbad during 2002â2004. The experiment was a randomized complete block design with four replications. The results of combined analysis showed that the effect of year was significant on the number of days from emergence to physiological maturity, resistance to lodging, the number of grains per pod, 1000 seed weight and seed and oil yield at the 1% level. In the second year of the experiment, decrease in the number of days from emergence to physiological maturity resulted significant decrease in 1000 seed weight, however existence of good climate condition, greater sunshine during flowering and seed formation periods resulted in increase in seed and oil yield (because of the decrease in lodging and increase in the number of seed per pod). The seed yield of the second and the first year of experiment were 3318 and 2359 kgha-1, respectively. The 1000 seed weight of Hyola 401 and Hyola 420 hybrids were more than those of other genotypes. The 1000 seed weight of Foreign Hyola 401, Safiabad Hyola 401, Borazjan Hyola 401 and Hyola 420 hybrids were 4.59, 4.64, 4.52 and 4.72 g, respectively. Option 500 had the highest oil percent (45.61%).The Hyola 420 hybrid had the highest seed (3560 kgha-1) and oil (2049 kgha-1) yield. Regarding of high yield and good vegetative characters, it seems that this hybrid and Hyola 401 can be recommended for planting in east part of Golestan. Â | ||
