从广东省杉木初级种子园中选出的39个优良无性系,其结实状况均不同,测定结果却均比初级种子园(对照)产量高出39.3%～64.0%。各无性系结实早,中期时单株球果产量分别介于0.1～4.7kg和0.7～11.3kg之间。经综合评定,从中筛选出23个结实多,种子品质好的优良亲本,其综合指标比初级种子园提高5.6%。所选的23个优良无性系,可作为广东省营建第一代种子园的材料。 The 39 elite clones selected from the Chinese fir primary seed orchards in Guangdong Province all showed different seed setting status, but the results were all 39.3% ~ 64.0% higher than that of the primary seed orchard (control). Seedlings of all clones in early and middle stages were between 0.1 ~ 4.7kg and 0.7 ~ 11.3kg respectively. After comprehensive evaluation, 23 elite parents with good seed quality and good seed quality were screened out, and its comprehensive index was 5.6% higher than that of primary seed orchard. Selected 23 excellent clones, can be used as construction of Guangdong Province, the first generation of seed orchard materials.
