摘要:

分别于1982、1989和1991年3次开展了老龄杉木无性系和杉木优良无性系互作为父母本的析因交配试验,共获得了58个交配组合,利用3片子代测定林历年的调查资料,进行了方差分析、数量遗传分析等,在此基础上初步提出了利用老龄杉木无性系作交配亲本时最好以杉木优良无性系作母本、老龄杉木无性系作为父本;选出建36、王台老龄杉木、闽清1老龄杉木和尤溪老龄杉木无性系4个优良的杉木交配母本,建36、三67和闽清1老龄杉木无性系3个优良的杉木交配父本;通过综合分析、评价,从参试的58个交配组合中选出各年都表现好的三54×闽1、王台×三66、闽1×锦8、闽2×建36、闽1×三67、尤溪×三67等6个交配组合,增产效果显著,这些优良交配组合既可作为杉木高世代种子园的建园材料,也可以通过群体无性化,提高繁殖系数,供生产应用,还可以作为高世代育种材料。

Abstract:

Factorial diallel matings were carried out in 1982,1989 and 1991 by using excellent clones of Cunninghamia lanceolata and some clones of old C. lanceolata as parents and 58 matches were obtained which were used to build 3 control-pollinated progenies tests. According to the analysis of variance and quantitative genetics for control-pollinated progenies tests,the preliminary result was that it was a good choice to use excellent clones of C. lanceolata as female parents and to use clones of old C. lanceolata as male parents. Four excellent female parents including Jian36,Wangtai,Minqing1 and Youxi and 3 excellent male parents including Jian36,San67 and Minqing1 were selected respectively. Based on the comparative analysis and evaluation of the performances of 58 matches,6 excellent matches including San54×Min1,Wangtai×San66,Min1×Jin8,Min2×Jian36,Min1×San67 and Youxi×San67 were selected. They were very striking in production and could be used for advanced generation seed orchard or applied in vegetative propagation. These matches also could be used for advanced generation breeding.
