| 摘 要： | 本文讨论了落叶松遗传改良的可能性及其潜力。其主要论点是:(1)落叶松(兴安落叶松、长白落叶松)种源间差异显著,种源遗传力较高;(2)落叶松个体选择效果明显.12～13年生的子代测定表明,家系间差异显著,遗传力很高,按家系选择可获得较大的遗传增益;(3)落叶松种间杂交优势明显、稳定,在F_2代申表现突出。

| Abstract: | This paper discusses the possibility and potentiality of Larch (Larix gmelinii,L. olgensis)genetic improvement. The difference between Larch provenances is significant and the provenance heritability may be improved; the effect of the individual and family is obvious,and hertabitity is strong,and can have genetic gain according to family selection, interspecific crossing vigor of Larch is very obvious and stable in F_2 generation. |
