摘要
对日本落叶松种子园59个自由授粉家系多点6年研究结果表明,家系生长性状有明显遗传变异,家系遗传型与环境交互作用明显。初步选出的优良家系树高遗传增益达7%～27%,可在生产中示范推广。
6-year determination of 59 free-pollination families at multiplots in L.leptolepis seed orchard showed that growth features among families existed obvious genetic variation,the role of genetic variation times environment is obvious,the height genetic gain of promising families selected is 7%～27%.
