摘　　要：山茱萸为传统珍贵中药材,长期处于野生和半野生状态,种内性状变异十分复杂。通过在自然资源中进行优良单株初选、复选和无性系测验等育种程序,筛选出果大皮厚,干出皮率高,加工性能好等综合性状优良的10个无性系,早期(4～7a)产量(干皮)超过71个参试无性系平均值的24 66%～82 44%;另选出特早熟及高含糖量无性系各1个,其中11个无性系于2002年通过浙江省林木良种审定委员会审定,并进行命名。As a precious traditional Chinese medicine,Cornus officinalis has been in wild or semi-wild conditions for a long time and the genetic variations within its species are very complicated.Through breeding procedures including preliminary selection,reselection and clonal tests of superior individual trees from natural resources,10 superior clones,which are large in fruit size,thick in sarcocarp and high in the percentage of dry sarcocarp and good in processing properties,have been selected.Their yields(of dry sarcocarp)at early stage(4～7 years) are 24.66%～82.44% higher than the average value of 71 tested clones.In addition,a specially early-maturing clone and a clone containing more sugars have been singled out.Eleven clones out of these clones pass the examination and appraisal conducted by the Examination and Appraisal Committee of Zhejiang Province for Superior Forest Species and Varieties in 2002 and are denominated.
