摘　　要：以吉林省白山市露水河林业局清水河林场内39个4年生核桃楸家系为材料,对其树高、地径进行调查并分析。结果表明:树高和地径在不同家系间、不同区组间、不同区组×家系间均达到极显著差异(P<0.01)水平。所有核桃楸家系的树高平均值为0.71 m,地径平均值为1.87 cm;树高与地径的变异系数分别为36.62%和36.36%;树高与地径的遗传力分别为0.80和0.81。相关分析结果表明,树高与地径呈极显著正相关关系。利用综合评价法,以10%的入选率选出优良家系4个。In this study,394-year-old Juglans mandshurica families in Qingshui Forest Farm,Lushuihe Forestry Bureau,Baishan city,Jilin Province were taken as materials,tree height and ground diameter were investigated and analyzed.The results showed that tree height and ground diameter were all significantly different between different families,between different groups,and between different groups×families(P<0.01).The mean of tree height and ground diameter of all J.mandshurica families were 0.71 m and 1.87 cm,respectively.The variation coefficients of tree height and ground diameter were 36.62%and 36.36%,respectively.The heritability of tree height and ground diameter were 0.80 and 0.81,respectively.The correlation analysis results showed that there was an extremely significant positive correlation between the tree height and ground diameter.Using the method of comprehensive evaluation,4 excellent families were selected with a selection rate of 10%.
