In order to investigate the reaction of canola autumnal species to delayed cultivation, a research study was carried out in Karaj Research Institute of Modification and preparation of sapling and seed in 1385-86. The test was performed with factorial form of random complete block plan with three repetitions consistying of planting time in two levels (10 Mehr& 10 Aban) and numbers in five levels such as: Elite, Opera, SLM046, Orient and Okapi. Each land test consists of 6 lines with 4 meters length and 30 cm gaps. The space of plants is 5 cm that 2 side lines are margins.4 middle lines were contemplated for determination of phonologic plant stages and measurement of some properties such as: numbers of pods in plant, diameter of pods, numbers of pod in shrub, lengths of pod in shrub, number of seeds in pod shrub, weight of thousand seeds, yield of seed, percentage of oil in seed, yield of oil seed. It was observed that all testing properties were reduced in delayed cultivation except the percentage of oil in seed. Consequently, the yield of oil seed in delayed cultivation, that is economically important, showed a significantly reduction.
