| 摘 要： | 对杉木初级种子园17个优树自由授粉子代的测定表明,优树子代间在苗期和幼林期存在着显著的生长差异.造林3年时,庆元10、遂昌1、三明74—55、桐庐104个子代高生长显著高于当地优良林分子代(对照),可获得8.69%的平均遗传增益.并反映出湘、闽中心产区优树子代一般优于本省子代,本省优树子代经度愈西,纬度愈南,生长愈佳的地理效应趋势.

| Abstract: | Seedling test of progenyfrom free pollination in Cunninghamia lanc-eolata/Xue Ding-fu* et al// Journal of Jiangsu Forestry Science & Technology. -1990, 17 (4) .-13-16, 30
The progeny test of Chinese fir obtained from free pollination of 17 elites m the primary orchard shown that there are obvious growth differ-ances between elite progenies, both in seedling stage and young tree stage. After planted 3 years, the height growth of 4 elites, named Qin-yuan 10, Suichang l, Sanming 74-55, and Tonglu 10 is large than that of local proyenances, the mean genetic gain is reach 8.69%. Meamwhile, the progeny of elites in Hunan and Fujian is better than that in Zhejiang
