林木种源试验研究已有160多年的历史了,而最近三十年来发展较快。据初步统计,现在几乎世界上所有从事人工林经营的国家,都开展了乡土和引进树种的种源研究,研究的树种已超过100个。引种研究与种源选择相结合,使引种工作获得新的活力。在种源研究基础上,种子园研究逐步完善起来。用优良种源中的个体进行杂交育种,丰富了基因资源,大大提高了育种成效。一、新中国林木种源研究的发展情况 Forest provenance research has been 160 years of history, and the rapid development in recent thirty years. According to preliminary statistics, almost all the countries that engage in plantation management in the world have conducted provenance studies of native land and imported tree species and have studied more than 100 tree species. Introducing research and provenance selection combine to make the introduction of new vitality. On the basis of provenance research, seed garden research gradually improved. Breeding of hybrids with individuals from fine provenances enriches genetic resources and greatly improves breeding effectiveness. First, the development of new China forest provenance
