摘　　要： 通过对全国10省(区、市)25个华山松种源32年选择研究,首次取得了对华山松种源研究的大量系统数据,确定了适宜种源,为宜昌市发展华山松提供了科学依据。结果表明:最适宜昌山区造林的是重庆城口和贵州威宁的种源,现实遗传增益比湖北巴东种源材积提高38.8%;比其它23个种源平均值材积提高23.3%;比25个种源平均值材积提高21.4%。 Lots of research data was obtained for the first time by means of selection study on 25 Pinus ar- mahdi provenance for 32 years in 10 provinces. In addition, appropriate provenance was determined, which provided scientific basis for developing Pinus armandi of Yichang. The results showed that the suitable prov- enance in Yichang mountain area was that of Chengkou in Chongqing and Weining in Guizhou. The actual genetic gain increased by 38.8% than that of Badong provenance, by 23.3% in average than that of other 23 kinds of provenance, and by 21.4% than that of 25 provenances.
