| 摘 要： | 对云南省内的藏柏8个种源36个家系开展自由授粉子代测定,结果表明,地径、树高和冠幅在种源和家系水平上均存在一定的变异,3个性状在种源和家系间都存在显著或极显著差异;地径、树高和冠幅种源遗传力分别为0.82、0.62和0.84,家系遗传力分别为0.76、0.76和0.77,地径、树高和冠幅在种源和家系水平上受强度遗传控制。选择出2个优良种源,地径、树高、冠幅平均遗传增益分别为11.36%、5.78%和10.1%;选择出4个优良家系,地径、树高和冠幅平均遗传增益分别为16.23%、16.22%和17.46%。

| Abstract: | A progeny test of 8 provenances and 36 open-pollinated families of Cupressus torulosa in Yunnan Province was done.The results showed that there were variations in basal diameter,seedling height and crown diameter among the provenances and families,and there were significant differences or extremely significant differences in the above three growth indices among the provenances and families.The provenance heritability of basal diameter,seedling height and crown diameter were 0.82,0.62,0.84 individually,and t... |
