A PRELIMINARY ANALYSIS ON GENETIC VARIANCE COMPONENT OF CHINESE FIR

Through the analyses on such traits as seed quality, seedling height and young tree growth of 104 Chinese fir families in 13 elementary seed orchards from 10 provinces or autonomous regions, genetic variance component of main economic traits among provenances and families within provenances, and genetic correlations between these traits were studied. According to the tree height growth, 15 better families were selected primarily.
