| 摘 要： | The preliminary assessment of progeny test in a seed orchard of Eucalyptus globulus Labill.ssp.globulus at Yipinglang State Farm of Yunnan Province in China was conducted.The trial was composed of 21 replications,with 2 trees on each plot,15 plots in each incomplete block,and 18 incomplete blocks in each replication,laid out in a α-design of 270 open-pollinated families.The families were of three categories (natural populations,local land race and seed orchard).They were further subdivided into 11 regions.The data from an assessment of growth,stem form and other characteristics of the young trees after being planted 2 years were analyzed.Results are as follows:the different categories differed significantly in their growth,with the families from seed orchards being the best.Regions also differed significantly in their growth.The families from the regions of Westem Victoria,Eastern Victoria and all three seed orchards were better than others.The tamilies from Yunnan had the best frost tolerant and its survival was the highest.For growth,stem form and fungal tolerance,the families from Yunnan were similar to that from Southern Tasmania and Eastem Tasmania.Two-tree plots were strongly recommended over singletree plot designs for large-scale progeny trials.

| Abstract: | The preliminary assessment of progeny test in a seed orchard ofEucalyptus globulus Labill ssp.globulus at Yipinglang State Farm of Yunnan Province in China was conducted. The trial was composed of 21 replications, with 2 trees
on each plot, 15 plots in each incomplete block, and 18 incomplete blocks in each replication, laid out in aa-design of 270 open-pollinated families. The families were of three categories (natural populations, local land race and seed
orchard). They were further subdivided into 11 regions. The data from an assessment of growth, stem form and other characteristics
of the young trees after being planted 2 years were analyzed. Results are as follows the different categories differed significantly
in their growth, with the families from seed orchards being the best. Regions also differed significantly in their growth.
The families from the regions of Western Victoria, Eastern Victoria and all three seed orchards were better than others. The
families from Yunnan had the best frost tolerant and its survival was the highest. For growth, stem form and fungal tolerance,
the families from Yunnan were similar to that from Southern Tasmania and Eastern Tasmania. Two-tree plots were strongly recommended
over singletree plot designs for large-scale progeny trials.
