A Preliminary Evaluation on the Selection of Superior Clones of Idesia polycarpa

Taking 20 clones of Idesia polycarpa as the research object,the excellent clones were evaluated and screened by analyzing the difference of growth,fruiting,oil content and other characters.The results showed that there were significant differences in panicle characters,fruit phenotype and fruit oil content among different clones.There was a significant correlation between cluster size and cluster weight.Six excellent clones were selected by principal component analysis,and the selection rate was 30%.The selected clones had the characteristics of high oil content,high seed yield and strong tree body.The selected superior clones provided a good material basis for breeding fine seeds or varieties in Sichuan.
