摘　　要：对林口县青山林场23年生杂种子代测定林63个家系径生长进行分析的结果表明,日本落叶松×兴安落叶松、兴安落叶松×日本落叶松正反交在生长量上存在极显著差异,日本落叶松×兴安落叶松组在径生长量上要比兴安落叶松×日本落叶松组大。落叶松种间生长量也存在差异,径生长由慢到快依次为长白落叶松、兴安落叶松×兴安落叶松、兴安落叶松×日本落叶松、兴安落叶松×长白落叶松、日本落叶松、日本落叶松×长白落叶松、日本落叶松×兴安落叶松。The diameter growth of 23 -years -old hybrid progenies of 63 families was analyzed at Qingshan forest center of Linkou County. The result showed that there was some differences among the species of larch. The difference of the growth reached at the 1% significant level of Japanese larch x Larix gmelinii and Larix grnelinii x Japanese larch. The diameter growth of Japanese larch x Larix grnelinii was higher than Larix gmelinii x Japanese larch whether population or individual. However there was some specific combining ability of individual.
