摘要: To study the origin of dwarfing genes used in barley breeding in China, pedigree data of more than 350 dwarf and semi-dwarf cultivars and entries developed since 1950 were collected. The results showed that 68.4% of them were derivatives of just six accessions: 'Chibadamai' (CBDM), 'Xiaoshanlixiahuang' (XSLXH), 'Cangzhouluodamai' (CZLDM), 'Aiganqi' (AGQ), 'Zhepi 1' and 'Yanfu Aizao 3' (YFAZ 3). Therefore, these six accessions are considered the main donors of dwarfing genes to barley cultivars bred in China. 'CBDM', 'XSLXH' and 'CZLDM' are landraces and were used between 1950 and 1980. 'AGQ', 'Zhepi 1' and 'YFAZ 3' are released cultivars used since 1980. 'CBDM', 'XSLXH', 'CZLDM' and 'AGQ' carry the same dwarfing gene uzu on chromosome arm 3HL. 'Zhepi 1' and 'YFAZ 3' likely are mutations at the sdw 1 locus.
