摘　　要：为了选育出适应性强、生长量高的华木莲优良单株,通过20多年的华木莲良种选育工作,采用优势木比较法对野生华木莲进行调查选优,采种、育苗、子代测定、对比试验等工作,以地径、胸径、树高、保存率等生长量指标进行了分析,选育出了宜林科华木莲1号。采用杉木、木荷与宜林科华木莲1号子代进行造林对比时,10年生的华木莲林分的保存率、平均胸径、平均树高分别达到82.5%、11.8 cm、12.6 m,且林相整齐,表明1号优株的F1代林分为速生林分。24个引种点的适应性区域试验表明宜林科华木莲1号具有较好的适应性。For breeding strong adaptability, high amount of plant growth, Sinomanglietia glauca＇ Yilinkehuamulian 1 ＇ was bred through the dominant tree comparison, progeny test and contrast test work after more than 20 years of selective breeding work. The forestation test of Cunninghamia lanceolata, Schima superba and S. glauca F1 showed that the preservation rate, average DBH and average tree high reached 82.5%, 11.8 cm, 12.6 m, respectively, in the ten-year-old old forest of S. glauca F1. The results also showed that the S. glauca is fast-growing tree species. The adaptability of regional test from 24 introduction points showed that S. glauca＇ Yilinkehuamulian 1 ＇ has good adaptability.
