Five different rapeseed genotypes were tested. The following traits were
considered: seed yield, seed germination, seed oil content, 1000 seed weight
and seed protein content and they were used to determine whether there is
significant or nonsignificant correlation. Highest average results were
determined in genotype G-3 (yield 2.544 kg; germination 90%; 1000 seed
weight 4,30 g; oil content 45,31% and protein content 19,83%) while G-5
(1.838 kg; 87%; 3,50 g; 44,77% and 17,28%) had the lowest average result of
observed parameters. Highly significant positive correlations were found
while comparing seed yield with 1000 seed weight (0.753**) and protein
content (0.726**). High significant positive correlation were also
determined comparing seed germination with 1000 seed weight (0.832**) and
protein content (0.892**). Also high significant correlation was determined
comparing 1000 seed weight and protein content (0.812**). Positive
significant correlations were found by comparing seed yield and seed
germination (0.644*). Path analysis indicated highest significant positive
direct effect of 1000 seed weight (0.716**) and protein content (0.666**) on
seed yield. High but negative significant value had seed germination
(-0.645**). In the study of indirect effects on seed yield, none of
significant effects were determined. The study of direct effects on oil
content showed that the seed germination had high significant positive
effect (-1.296**) on oil content. Significant but hot high effect has seed
yield (0.556*). In other two traits it was determined negative high
significant effects (1000 seed weight - 0.797** and protein content -
0.717**) on seed oil content. The existence of indirect significant effects
on oil content in four cases was determined.
