以引自云南香格里拉的4年生45个丽江云杉家系为研究对象，在甘肃省小陇山林科所经过苗圃测定4 a，观测各家系的苗高、当年新梢长、一级侧枝数、主梢上的芽数、南北冠幅、顶轮侧枝总长，并对家系间6个生长性状指标进行了分析，采用综合选择法评选优良家系。结果表明：丽江云杉家系间6个生长性状的变异系数较高，变幅在11．64％～39．14％；各性状间均存在极显著差异，遗传力较大；主要生长指标苗高与其它生长指标都存在极显著的相关；多性状综合评选，选出8个优良家系，这些家系的苗高实际增益为18．67％～60．01％，遗传增益为17．93％～57．61％。

The experimentwas conducted to study the seedling height ,the length of newshoot , the numberof first order lateral branches , the bud number of leading shoot, the norths-outh crown width and the preserving rate of total length of top wheel lateral branch with four-year Picea likiangensi of 45 families for four years at Xiaolongshan Forestry Institute in Gansu Prov-ince.Six growth character indexes were analyzed by using the comprehensive method of choice selection good family.Six growth characters of variation coefficient were higher, ranging from 11.64%to 39.14%.Various characters were very sig-nificant differences and the heritability was also highter.Seedling height and other growth indexes had significant correla-tion.By combined character selection eight good families were selected, these genealogical seeding high of practical gain were 18.67%-60.01%, and the genetic gain were 17.93%-57.61%.
