To study the origin ofdwarfing genes used in barley breeding inChina, pedigree data of more than 350 dwarfand semi-dwarf cultivars and entriesdeveloped since 1950 were collected. Theresults showed that 68.4% of them werederivatives of just six accessions:`Chibadamai' (CBDM), `Xiaoshanlixiahuang'(XSLXH), `Cangzhouluodamai' (CZLDM),`Aiganqi' (AGQ), `Zhepi 1' and `Yanfu Aizao3' (YFAZ 3). Therefore, these sixaccessions are considered the main donorsof dwarfing genes to barley cultivars bredin China. `CBDM', `XSLXH' and `CZLDM' arelandraces and were used between 1950 and1980. `AGQ', `Zhepi 1' and `YFAZ 3' arereleased cultivars used since 1980. `CBDM',`XSLXH', `CZLDM' and `AGQ' carry the samedwarfing gene uzu on chromosome arm3HL. `Zhepi 1' and `YFAZ 3' likely aremutations at the sdw 1 locus.[PUBLICATION ABSTRACT]
