| 摘 要： | 以59个白桦(Betula platyphylla Suks.)自由授粉家系子代测定林为研究对象,对树高、胸径、纤维长度、纤维宽度、纤维长宽比、苯醇抽提物含量和综纤维素含量7个性状进行了差异显著性分析和多重比较分析,运用选择指数法开展了白桦纸浆材优良家系选择,并对这些入选家系作了遗传增益估算.结果表明:这些性状在家系间差异达到极显著水平,各性状家系遗传力为0.52～0.92;遗传变异系数除树高(20.71%)较大外,其它性状皆小于5%.对7个性状进行了多重比较并绘制了散点图,发现选择的性状标准不同,选择出的优良家系也不尽相同.进一步运用等权重的指数选择方法综合选择出了7个生长和材性兼优的家系.入选家系各性状的遗传增益为0.24%～9.52%,生长性状的遗传增益大于材质性状的遗传增益.

| Abstract: | A study was conducted to discuss the significant differences in tree height,diameter at breast height(DBH),fiber length,fiber width,ratio of fiber length to width,benzene-alcohol extractive content and holocellulose content between 59 filial generations derived from open-pollinated Betula platyphylla families,and multiple comparisons were also made.According to the selection index method,superior families for pulpwood purpose were selected on the southern slope of Xiaoxing'an Mountains,and the genetic gains... |
