Comparison and Screening of Growth Traits of 114 Clones in Grafted Seed Garden of Manglietia yuyuanensis
摘要
Abstract
To accelerate the breeding process of precious native broad-leaved tree species,a growth survey was conducted on a 19 a grafted seed garden of Manglietia yuyuanensis at the Weimin State-Owned Forest Farm in Shaowu,Fujian Province.The results showed that:the 114 tested clones exhibited extremely significant differences(P<0.05)in tree height,diameter at breast height(DBH),and single-tree volume.All traits except crown width exhibited moderate heritability levels,indicating substantial genetic control.Using cluster analysis integrated with major growth traits,seven elite clones were selected.Compared with the whole popula-tion,the genetic gains of tree height,diameter at breast height and timber volume were 7.24%,7.58% and 25.69% .The perform-ance stability of each elite clone still requires further observation.Especially,SW-020 and SW-002,as individuals with extremely outstanding performance,require focused verification.Their suitable promotion areas must be investigated through extensive regional-ized cultivation trials in subsequent studies.关键词
