摘要
通过对日本落叶松优良无性系的引种栽培试验,初选出适宜于山西省中山山地发展的6个日本落叶松无性系。经对其遗传力测定,树高和地径的遗传力分别为0.351和0.31;利用性状表现水平分析法对其性状表现进行评估,评估结果由高到低依次为日永8、日永85×长3、日永85×长4C、日永8×长12、日永11和日永85×长13。
The clones of Japanese larch were introduced and researched, of which six clones were selected and adaptable to grow in mountain land of Shanxi Province. The objectives of the study are： to determine heritability and to evaluate characteristic performance. The results indicate that the heritability of tree height and the diameter of trunk near ground is 0. 351 and 0.31, respectively. The order of characteristic performance of clones is different ： Riyong 8〉Riyong85 × Chang 3〉Riyong 85 × Chang 4C〉Riyong 8 × Chang 12〉Riyong 11 〉Riyong 85 × Chang 13.
