本文在落叶松种间和长白落叶松种源选择的基础上,开展了56株优树自由授粉子代评比工作。对4年生各家系树高显著性测定表明,在1％水准上家系间差异达极显著,优于对照树高的有34个家系,占家系总数的59.6％。通过家系的表型来评定母本的遗传品质,表现出母本具有较优良的遗传特性。初步为第一代无性系种子园和新建第一代无性系改良种子园以及将子代测定林改建为实生苗种子园提供依据和物质基础。
Based on the selection of provenances of Larix gmelinii and Larix gmelinii, 56 excellent trees were selected for free pollination. The significant tree height determinations of four-year-old families showed that there was a significant difference in the pedigree at the 1% level, with 34 pedigrees superior to the control tree, accounting for 59.6% of the total pedigrees. The genetic quality of the female parent was evaluated by the phenotype of the pedigree, showing that the female parent had better genetic characteristics. Initially for the first generation clonal seed orchard and the new first-generation clonal improved seed orchard and offspring test forest converted into seedling seed orchard to provide the basis and material basis.
