Studies on the Genus Paeonia Ⅲ. Heritabilities, Genotypic Correlations and Path-coefficient Analysis on Some Characters of Tree Peony

1. Heritability values of stem length, branch numbers per plant, internode length and fresh plant weight were higher than those of stem diameter, leaf numbers per branch and bud numbers per branch in tree peony(Paeonia suffruticosa Andrew). 2. Genotypic correlations between fresh plant weight and other characters indicated that plant weight was genetically correlated with branch numbers per plant, stem diameter, stem length, leaf numbers per branch and internode length, except bud numbers per branch, respectively. 3. Furthermore, it was also recognized that stem diameter, leaf numbers per branch and internode length of tree peony were affected to total weight of plants directly and indirectly by the path coefficient analysis method.
