杂种落叶松优良家系相互作用及稳定性分析

Analysis of Interaction and Stability Between Fine Families of Hybrid Larch

对13个家系数据进行分析的结果表明,各家系间差异极显著,杂种落叶松相对于单亲本落叶松优势非常明显。杂种落叶松不同品种在不同地点的高生长量都远超单亲本落叶松,且不同品种在不同地点具有一定的稳定性,日×兴、兴×日的正反交品种在黑龙江省各地表现良好,具有一定的推广价值。

The analysis of variance showed that the difference among 13 families reached at the 1% significant level. The heterosis of hybrid larch was superior to that of the single parent. The height increase of hybrid larch far exceeded the single parent with different varieties and had stability in different places. The reciprocal cross of Japanese larch x Larix grnelinii,, Larix gmelinii x Japanese larch was growing well in Heilongjiang Province. They deserved popularization.
