Abstract: In the chinese sorghum production the application cytoplasm has A1 and the A2 two kind of types. The male-sterile line cell nucleus has the Kafir nuclear system, the kaoliang nuclear system, trend Kafir nuclear system and the Shallu nuclear system. The r-line idioplasm mainly is the kaoliang and trend kaoliang type.The heterosis use model mainly is the Kafir×kaoliang, the kaoliang×kaoliang, trend Kafir×trend kaoliang, the Shallu×trend kaoliang. The plant improves miadle highly by the high stalk, causes the output to raise large. The male-sterile line improve should by the Shallu and the Kafir or the Shallu hybrid primarily, the r-line improve should by the kaoliang and Hegari or the kaoliang hybrid primarily, may maintain two kisses the heredity difference, in order to compounds the high yield hybrid.
