摘要
根据１９８９～１９９３年贵州黎平东风林场杉木种子园无性系开花物候数据，评价了种子园无性系开花同步水平，探讨了开花物候对种子园配子贡献、自交率和子代基因型值的影响，提出了根据开花结实习性综合估算基因型值的基本模型。
According to the data of flowering phenology among clones from Chinese fir seedorchard of Dongfeng forest farm in Liping county,Guizhou province,the degrees of reproductivesynchronization between all mating pairs of clones in seed orchard were measured.The effects offlowering phenology on gamete contribution of clones,the proportion of self-pollination and ge-netic values of progenies were discussed,and the mathematical methods used in estimation of ge-netic values on the basis of flowering characteristics of clones in seed orchard were provided。
