Currently, oilseeds are of particular importance among agricultural crops and
constitute the second food reserves in the world after cereals. Camelina is a medicinal-oil plant that
is able to grow in different weather and soil conditions and compared to other oil seed plants, it
needs less water, fertilizers, pesticides and more resistance to cold. On the other hand, the
temperature during the flowering and seed setting period is considered a very important indicator
for estimating the yield potential of camellia seeds.
Separate simple variance analysis of the data of both environments showed that with
the delay in planting and occurrence of heat stress, plant height, stem diameter, number of branches,
number of pods per plant, number of seeds per pod, thousand seed weight, seed yield, Oil percentage,
oil yield and chlorophyll content decreased. In the date of conventional planting, the grain yield in
line 1 (496.08 gr) was more than other lines, and in the conditions of heat stress caused by the delay
in planting, lines 41 and 44 (224.15 and 201.59 gr) had the highest grain yield. Under normal
conditions, the correlation between seed yield and oil yield traits (r=0.973**), number of pods per
plant (r=0.816**), thousand seed weight (r=0.546**), diameter bottom (r=0.557**), middle
diameter (r=0.538**), stem top diameter (r=0.500**) and the number of sub-branches (r=0.407)
means It was positive. Under stress conditions, grain yield with oil yield traits (r=0.956**), stem
middle diameter (r=0.717**), stem top diameter (r=0.720**), stem bottom diameter (* *r=0.693),
number of seeds in Khorjin (r=0.624**), thousand seed weight (r=0.515**) and chlorophyll b
(r=0.409) showed a positive correlation. The results of the stepwise regression showed that in the
normal environment, three attributes of the number of spikelets per plant, the weight of 1000 seeds
and the number of seeds per spikelet were entered into the model as influential traits, which finally
justified 96% of th
