摘要
对 2 1 7个福建省杉木优良无性系 4个年度的测定结果进行了分析 ,并对各生长性状的遗传参数进行了估算。结果表明 ,各主要生长性状的差异在无性系间均达到显著或极显著水平。通过遗传测定 ,从 2 1 7个优良无性系中评选出 2 3个速生优良无性系 ,与杉木第 1代种子园子代相比 ,入选的优良无性系具较高的生产力水平和增产效果 ,适宜于在福建省北部或其他生态条件相近的地区推广应用。表 5参
The genetic test of 217 super clones of Chinese fir in Fujian Province in four years were analyzed in this paper.The geneticparameters of growth related traits were also estimated.The results showed that the difference of main growth related traits among clones were significant.Twenty three super clones of Chinese fir were selected from 217 clones according to this genetic test,which have higher productive level and genetic gain than that of progeny from first generation seed orchard and therefor fit for the application in north of Fujian Province and similar ecological condition related areas.
