摘　　要：系谱分析表明 ,尺八大麦、萧山立夏黄、沧州裸大麦、矮秆齐、浙皮 1号和盐辐矮早 3是我国大麦育种的主要矮源。 2 0世纪 5 0年代以来我国育成的大麦矮秆和半矮秆品种 (系 ) ,主要是以它们为矮秆亲本的 6大衍生系统组成 ,分别占 14 .5 %、2 1.4 %、11.4 %、5 .7%、7.5 %和 7.5 %。其中尺八大麦、萧山立夏黄和沧州裸大麦主要在 80年代以前使用 ,而矮秆齐、浙皮 1号和盐辐矮早 3则是 80年代大量使用的矮源。在这 6个矮源中 ,前 4个携带相同的矮秆基因uz,位于大麦 3H染色体长臂之上。The pedigrees of 332 dwarf and semi dwarf varieties and entries bred since 1950 in China were collected and analyzed. The results showed that varieties of Chibadamai, Xiaoshanlixiahuang, Cangzhouluodamai, Aiganqi, Zhepi1 and Yanfuaizao3 were the main dwarfing gene sources in China's barley breeding. Most of modern varieties and entries were the derivatives of the 6 dwarf land-races and cultivars and they accounted for 14.5%, 21.4%, 11.9%, 5.7%, 7.5% and 7.5% respectively. Among them Chibadamai, Xiaoshanlixiahuang and Cangzhouluodamai were used in barley breeding from 1950 to 1980, but Aiganqi, Zhepi1 and Yanfuaizao3 began to be used in 1980. Besides, Chibadamai, Xiaoshanlixiahuang, Cangzhouluodamai and Aiganqi carried the same dwarfing gene uz which located, on the long arms of their 3H chromosomes respectively.
