摘要
本文通过对马尾松优树自由授粉子代田间对比试验,经多性状多层次的统计分析表明:优树子代的高、径生长性状表现能预测干形、生长势、花粉量、冠形指标,年生长期的长短对表型值影响显著。在85个优树子代中,选出23个优良家系。利用主分量值和遗传距离聚类的综合评选法,反映出子代在生长、形质两方面的优良特性。
Field comparison experiments on filial generations from free pollination of good trees of Masson' s pine and multi-character and multi-level statistical analyses have shown that the trunk form, growth vigour, pollen amount and canopy indexes can be estimated according to growth phenotypes in height and diameter of filial generations of fine trees, and that the length of annual growth period has a remarkable effect on phenotypic alues. 23 good families have been selected out of 85 filial generations.
