摘　　要：在广西南宁和山西平遥两地分别种植6个微胚乳玉米杂交组合,测定其产量性状和含油率。结果表明,不同的杂交组合在异地种植的产量性状和含油率表现不尽相同。组合2在山西平遥的单穗重、单穗粒重、整粒含油率和胚含油率都最高,其次是在山西平遥种植的组合1,且组合1和组合2在山西平遥的大部分产量性状及含油率高于广西南宁,而其余4个组合在山西平遥种植的单穗粒重和整粒含油率远低于广西南宁。6 micro-endosperm maize cross combinations were planted separately in Nanning of Guangxi and Pingyao of Shanxi,and the yield traits and oil percentage were measured.The results showed that the yield traits and oil percentage of 6 combinations were different when planted in different places.The ear weight,kernel weight per ear,oil percentage of the combination 2 in Pingyao were the highest compared with the other treatments,then that of the combination 1 in Pingyao.The yield traits and oil percentage of the combination 1 and the combination 2 in Pingyao were higher than that in Nanning.While the kernel weight per ear and oil percentage of the other four combinations in Pingyao were lower than that in Nanning.
