中国林学会林木遗传育种分会于1991年11月14～19日在贵阳市召开了学术报告会。出席大会代表有139名。会上收到论文150多篇。首先进行了大会交流。开始由林木遗传育种专业委员会主任张培杲先生介绍了1986～1991年我国林木遗传育种工作取得的成就和进展情况。5年来选择和收集了针阔叶优树3万多株,选育优良种源、家系和无性系近2000个,主要造林树种无性繁殖技术有所突破,并确定了其最短决选年龄(早期预测),缩短了育种年代;基因的分离和转入也取得可喜成效。在此基础上,建立了各种试验林4834.05公顷,其中15个树种的种源试验林705多公顷,
The Chinese Academy of Forestry Branch of Forest Genetics and Breeding held an academic report in Guiyang from November 14 to November 19, 1991. There were 139 representatives attending the conference. At the conference received more than 150 articles. First of all, the conference was held. Beginning with Mr. Zhang Peixuan, director of Forest Genetics and Breeding Committee, introduced the achievements and progress made in the field of tree genetic breeding in China from 1986 to 1991. Over the past five years, more than 30,000 coniferous and broad-leaved trees have been selected and screened, and nearly 2,000 elite breeding provenances, families and clones have been selected and breached. A breakthrough has been made in the clonal propagation of the main afforestation species, Forecast), shortening the breeding age; gene separation and transfer also made gratifying results. On this basis, a total of 4834.05 hectares of various experimental forests were established, of which, more than 705 hectares of provenance forests of 15 tree species,
