摘要
对帽儿山10年生白桦种源试验林中的帽儿山、东方红和乌伊岭3个优良种源的30个家系进行调查研究。结果表明:不同家系在树高、胸径、材积和纤维素含量上均存在显著差异。对各性状进行遗传参数估算、主成分分析和不同的聚类分析,最终筛选出东方红14、帽儿山9和帽儿山14共3个纤维材优良家系,这3个家系纤维素质量分数的遗传增益分别为5.08%、4.35%和4.16%,材积遗传增益分别为23.96%、22.85%和21.55%。
A survey was conducted on 30 families of three fine provenances （Maoershan, Dongfangbeng, Wuyiling） in a provenance trial stand of 10-year-old Betula platyphylla in Maoershan Experimental Forest Farm, Shangzhi City. Remarkable differences in diameter at breast height, tree height, stem volume and cellulose content were found between different families. Three fine families, Dongfanghong No. 14, Maoershan No. 9 and Maoershan No. 14, were screened out by means of genetic parameter estimation, principal component analysis and cluster analysis. The genetic gains in cellulose content and stem volume for Dongfanghong No. 14, Maoershan No. 9 and Maoershan No. 14 were 5.08%, 4.35% , 4.16% and 23.96%, 22.85% , 21.55%, respectively.
