Table 3. Genetic diversity of the genome in R population and the selected population.

Chr	π-Ra	π-Sb	DRc
A	0.370	0.364	1.55%
C	0.368	0.358	2.70%
AC	0.369	0.361	2.10%

Chr represent the chromosome; A, C and AC represent the A and C subgenome, and the whole genome of rapeseed, respectively.

^aThe average value of genetic diversity (π) for the R population.

^bThe average value of genetic diversity (π) for the the selected population.

^cThe decrease ratio of genetic diversity.
