通过对长白落叶松２５６个优良基因型的评定，筛选出种子产量优良的无性系７个；材积生产优良的无性系２０个；综合优良无性系１８个；优良家系１２个；最佳杂交组合１０个；反交效应好的组合有８个；一般配合力好的有２个。经对参试家系进行多点造林分析，划分出６种生产类型。即高产稳产型。中产稳产型、低产稳产型和高产非稳产型、中产非稳产型、低产非稳产型。 Through the evaluation of 256 excellent genotypes of Larix olgensis, 7 clones with excellent seed yield were screened out; 20 clones with excellent yield were produced; 18 with excellent clones; 12 with excellent families; and the best hybrid combinations with 10 A; combination of good anti-cross effect there are eight; with a good general co-2. After analyzing the multi-point afforestation of the pedigree, six kinds of production types were divided. That is, high and stable production. The middle-class stable production, low-yield stable and high-yield unsteady, middle-yield unsteady, low yield unsteady.
