Study on selection of plus tree from superior provenances and families of Fokienia hodginsii

YU Ge-fei

Abstract

Based on provenance trial of 19 geography provenances and 48 families, 10 superior provenances and 14 families were tentatively selected with the volume genetic gain of 16.09?%～88.70?%?15.19?%～184.80?% respectively. Based on national standard of Fokienia hodginsii, 179 plus trees were selected with the volume genetic gain of 17.45?%～122.51?%?3.30?%～191.69?% than superior provenances and families respectively.
