Abstract

The research was on progenies of open-pollinated families from clonal seed orchards of Cupressus funebris at age of 15 .It is showed that the average growth of the height , diameter at breast height and stem volume of offspring in clonal seed orchards were 13.12 %, 13.69 % and 30.85 % higher than the control group respectively , and their average genetic gains were 7.82 %, 7.69 % and 17.03 % higher than the control group respectively . Eleven superior families were selected according to their timber traits with the methods of the Least Significant Range , the trait performance analysis and the estimation of breeding value .Their real gains were between 46.35 % and 108.65 %with the average value of 64.21 %;their genetic gains were between 25.58 % and 59.96 %with the average value of 35.44 %.Good breeding benefits could be acquired from the application of the superior families in the production .[ Ch , 3 tab .22 ref .]
