The tested lines originated from breeding programmes of different breeders. Each set of cultivars was tested in a different year from 2001 to 2004 in multi-location trials with four replicates. There was no consistency in yield superiority of DH or PD lines and in all four sets the differences between the means of DH and PD groups were insignificant.
