Abstract: The survey of cabbage varieties released during 1982—2012 in China were overviewed
and summarized. Their parents’ origination and combination rule were analyzed based on the pedigree data.
The results showed that there were 108 flat-head varieties，88 round-head varieties and 23 pointed-head
varieties among all the 219 cabbage varieties released，which included 183 hybrids，accounting for 83.56%.
The hybrid proportion reached 96.74% in recent 10 years. The analysis of 176 varieties with known
parental origination indicated that all the varieties were combined with 261 parental lines，which could be
traced to 171 original resources，i.e. 67 domestic landraces and 104 alien accessions. In all the original
resources，the number of‘Heiye Xiaopingtou’derived varieties was the most（38），followed by‘Beijing
Zaoshu’（27）. The pedigree analysis showed that the combinations with two parents from different
geographical area or having great botanical characteristic difference always had strong heterosis. The rule
of parental selection and combination was revealed based on the parental characteristic of several major
varieties in China. Pedigree of foundation parents‘Beijing Zaoshu 01-20’and‘Heiye Xiaopingtou 21-3’
were drawn in this study.
