日本落叶松(Larix Leptolepis Gord.)和欧洲落叶松(L.decdua Mill.)种植表明，这些物种及其杂交种将比松树和云杉长得更长，特别是在更好的莱克州森林土壤上。落叶松具有足够的遗传多样性，生长迅速。它还易于杂交，具有良好的木材质量，对硬皮病和云杉芽孢虫具有抗性，并适应各种土壤。最近，威斯康星州阿普尔顿的造纸化学研究所建立了一个使用种子园方法的合作落叶松改良计划。制浆研究表明，18-23年生的落叶松和落叶松杂交种(Larix X Euroepis Henry)的硫酸盐产量高于50-60年生的樟子松(Pinus bansiana Lamb.)其纸浆强度特性与针叶松相似。
Preliminary comparisons between Japanese (Larix leptolepis Gord.) and European larch (L. decidua Mill.) plantings indicate that these species, together with their hybrids, will outgrow pine and spruce, particularly on the better Lake States forest soils. Larch has adequate genetic diversity and grows rapidly. It also hybridizes readily, has good wood quality, is resistant to scleroderris canker and spruce budworm, and is adapted to a variety of soils. Recently, the Institute of Paper Chemistry, at Appleton, Wisconsin, established a cooperative larch tree improvement program using seed orchard approach. Pulping studies indicate that 18- to 23-year-old larch and larch hybirds (Larix x eurolepis Henry) can produce higher kraft yields than 50- to 60-year-old jack pine (Pinus banksiana Lamb.) and with pulp strength properties similar to those of jack pine.
