This table should be read in conjunction with the HGCA Recommended List of Winter Oilseed Rape for 2013/14

Conv = conventional open-pollinated variety   RH = restored hybrid                [ ] = limited data
# = Thorin, PX106, DK Sequoia and PX104 are semi-dwarf varieties that are believed to carry the Bzh dwarfing gene in the heterozygous state but this has not been verified in RL tests
