摘　　要：于2022年在福建省漳平五一国有林场杉木第3代种子园中,对88个建园亲本无性系的冠幅,雌、雄球花和单株球果产量进行调查和分析。结果表明:88个无性系亲本10年生时冠幅的平均值为3.75 m,变异系数平均值为5.97%;单株雌花数量平均值为1088个,变异系数平均值为58.82%;单株雄花数量平均值为1777个,变异系数平均值为59.14%;单株球果产量平均值为2573个,变异系数平均值为31.97%。雌、雄花量的变异系数最大,均接近60%;冠幅生长的变异系数最小,低于6%。相关分析结果表明,雌、雄花量间的相关性不显著,雌花花量与单株球果产量间的相关系数值最大,冠幅与单株球果产量间的相关系数值次之,雄花量与单株球果产量的相关系数值最小。第3代种子园亲本生长结实性状变异分析将为选择冠幅、雌雄球花数量或单株球果产量均综合表现稳定的无性系提供依据。The crown width,male and female cones,and single plant cone yield of 88 established parent clones were surveyed and analysed in the third generation Chinese fir seed orchard of Wuyi State Owned Forest Farm in Zhangping,Fujian Province.The results were as follows:at 10 years old,the average of crown width of the 88 parents clone was 3.75 m,and the average of variation coefficient was 5.97%;the average number of female flowers per plant was 1088,the average of variation coefficient was 58.82%;the average number of male flowers per plant was 1777,the average of variation coefficient was 59.14%;the average yield of cones per plant was 2573,the average of variation coefficient was 31.97%.The variation coefficient of female and male flower quantity was the highest,both close to 60%,while the variation coefficient of crown width growth was the lowest,below 6%.The relation research showed that the correlation of flower quantity between male and female was not significant,the correlation coefficient between female flower quantity and single plant cone yield was the highest,followed by the correlation coefficient between crown width and single plant cone yield,and the correlation coefficient between male flower quantity and single plant cone yield was the lowest.Based on the crown growth,flower number of male and female,and cones yield per plant of 88 clones,the clones with stable crown growth,flower number of male and female,and cones yield per plant were sorted and selected,which would provide excellent materials for the construction of higher generation seed orchard.
