摘　　要：在黑龙江、吉林以及辽宁省8个地点对杂种落叶松21个处理进行了区域化试验,用Eberhart和Rus-sell模型等4种方法对5年生树高进行稳定性分析,并筛选出生长好且稳定性高的处理。结果表明:5年生树高和胸径各地点处理间差异均极显著。各地树高和胸径生长较好的家系分别为:北安,日5×兴9、日3×兴9;草河口,日5×长77-3、兴10×日13、兴5×兴9;错海,日12×兴9、日5×兴9、兴10×日13;富锦,日5×兴9、兴7×日77-2、兴6×和6;吉林,日3×石51、日5×长78-3、兴10×日13;林口,日5×长78-3、兴7×日77-2、兴6×和6;尚志,日5×长77-3、日5×兴9;铁力,日3×兴9、日5×兴9、兴10×日13、兴7×日77-2.5。5年生树高多点联合方差分析表明:处理间、地点间以及处理×地点差异均极显著。秩次分析法与Shukla模型适合评价杂种落叶松生长的稳定性。家系日5×长78-3、日5×兴9、兴5×兴9生长好且稳定性高,家系日5×长77-3、兴6×和6、兴7×日77-2生长好但不稳定。Regional test of twenty-one treatments on hybrid larch was conducted in eight areas in Heilongjiang,Jilin,and Liaoning Provinces.Stability of five-year-old trees at juvenile stage was analysed and the treatments with high stability and fast growth were tested by the Eberhart Russell model,the additive main-effect and multiplicative interaction（AMMI） model,Shukla model and Ranking analysis.Results showed that the difference in tree height and diameter at breast height（DBH） of hybrid larch trees in each area between different treatments was extremely significant.The families with favorable tree height and DBH in the eight areas were Larix kaempferi 5 × L.gmelinii 9 and L.kaempferi 3 × L.gmelinii 9 in Beian,L.kaempferi 5 × L.olgensis 77-3,L.gmelinii 10 × L.kaempferi 13 and L.gmelinii 5 × L.gmelinii 9 in Caohekou,L.kaempferi 12 × L.gmelinii 9,L.kaempferi 5 × L.gmelinii 9 and L.gmelinii 10 × L.kaempferi 13 in Cuohai,L.kaempferi 5 × L.gmelinii 9,L.gmelinii 7 × L.kaempferi 77-2 and L.gmelinii 6 × he 6 in Fujin,L.kaempferi 3 × shi 51,L.kaempferi 5 × L.olgensis 78-3,L.gmelinii 10 × L.kaempferi 13 in Jilin,L.kaempferi 5 × L.olgensis 78-3,L.gmelinii 7 × L.kaempferi 77-2 and L.gmelinii 6 × he 6 in Linkou,L.kaempferi 5 × L.olgensis 77-3 and L.kaempferi 5 × L.gmelinii 9 in Shangzhi,L.kaempferi 3 × L.gmelinii 9,L.kaempferi 5 × L.gmelinii 9,L.gmelinii 10 × L.kaempferi 13 and L.gmelinii 7 × L.kaempferi 77-2 in Tieli.Multi-point ANOVA analysis showed that the differences in tree height between different treatments,areas and the combination of treatment and area were extremely significant.Ranking analysis and Shukla model are suitable for evaluating the growth stability of hybrid larch.The growth and stability of L.kaempferi 5 × L.olgensis 78-3,L.kaempferi 5 × L.gmelinii 9 and L.gmelinii 5 × L.gmelinii 9 are optimal,while L.kaempferi 5 × L.olgensis 77-3,L.gmelinii 6 × he 6 and L.gmelinii 7 × L.kaempferi 77-2 grow well but have poor stability.
