摘　　要：在黑龙江、吉林和辽宁3省7个试验点对杂种落叶松13个处理播种育苗,用Eberhart和Russell模型等5种方法进行苗期稳定性分析,并筛选生长好且稳定性高的处理。结果表明,1年生和2年生高生长表现出极显著的正相关,Pearson和Spearman相关系数分别为0.535和0.536,2年生各地点处理间均差异极显著(P<0.01),各地生长较快的家系:草河口为日本落叶松Larrix kaempferi5×兴安落叶松Larrix gmelinii12,兴安落叶松9×日本落叶松76-2;错海为日本落叶松5×长白落叶松Larrix olgensis77-3,日本落叶松5×长白落叶松78-3;富锦为兴安落叶松9×日本落叶松76-2,兴安落叶松5×兴安落叶松9;吉林为兴安落叶松12×兴安落叶松2,兴安落叶松7×日本落叶松77-2;林口为兴安落叶松12×兴安落叶松2,兴安落叶松5×兴安落叶松9;尚志为日本落叶松5×兴安落叶松9,日本落叶松5×长白落叶松77-3;铁力为兴安落叶松5×兴安落叶松9,兴安落叶松7×日本落叶松77-2。AMMI模型方差分析表明,处理间、地点间以及处理×地点差异极显著(P<0.01),方差分量分别为16.00%,56.25%,27.75%。AMMI模型、George模型和高稳系数法适合评价苗期高生长的稳定性。家系日本落叶松5×长白落叶松78-3,日本落叶松11×兴安落叶松2,兴安落叶松9×日本落叶松76-2和兴安落叶松5×兴安落叶松9生长好且稳定性高,兴安落叶松12×兴安落叶松2,日本落叶松5×兴安落叶松9,日本落叶松5×长白落叶松77-3和日本落叶松3×兴安落叶松9家系在部分地区生长好。Thirteen treatments of hybrid larch（Larix spp.） were sown and raised in nurseries at seven sites in Heilongjiang,Jilin,and Liaoning Provinces.Pearson＇s and Spearman＇s correlation analyses between one-year old and two-year old trees were conducted.Also,seedling stage stability was analyzed,and treatments with high stability and good growth were tested with five models：Eberhart Russell,the additive main-effect and multiplicative interaction（AMMI）,the George C.C.Tai,HSC,and Shukla.Results showed significant positive correlations between one-year old and two-year old for Pearson＇s（r = 0.535） and Spearman＇s（r = 0.536） correlation analyses.For two-year old trees,using the AMMI ANOVA,differents of treatments at each location were extremely significant（P0.01） with variance components for treatments = 16.00%（P0.01）,locations = 56.25%（P0.01）,and treatment × location = 27.75%（P 0.01）.Four treatments（Larix kaempferi 5 × L.olgensis 78-3,L.gmelinii 9 × L.kaempferi 76-2,L.kaempferi 11 × L.gmelinii 2,and L.gmelinii 5 × L.gmelinii 9） showed good growth and high stability;whereas four treatments（L.gmelinii 12 × L.gmelinii 2,L.kaempferi 5 × L.gmelinii 9,L.kaempferi 3 × L.gmelinii 9,and L.kaempferi 5 × L.olgensis 77-3） grew well in some areas.
