摘　　要：以杂交育种获得的38份种质为材料,以当年春梢作为穗条,采用随机区组高接换冠试验,研究不同种质间自然座果率、单株产果量、鲜果含油率、单株产油量的差异。结果表明:38个种质间的自然座果率、单株产果量、鲜果含油率,单株产油量差异极显著。以单株产油量为指标,初步筛选出高产新种质8份,其年平均产油量为0.6 kg/株以上。其中以C18单株产油量最高,为1.11 kg;C16、C38单株产油量也较高,分别为1.02 kg、0.93 kg。In this article,38 varieties obtained by hybridization as material,current spring shoots as scion, through engrafting in crown of a tree by randomized block test,the fruit setting rate,individual fruit yield,fruit oil content and individual oil production of were study.The result showed that the fruit setting rate,individual fruit yield,fruit oil content and individual oil production of 38 varieties were extremely different.Eight new varieties with high individual oil production were preliminary selected,their annual individual oil production reached more than 0.6 kg;the individual oil production of C18 ,C16 and C38 reached 1.11 kg,1.02 kg and 0.93 kg respectively.
