Growth of single-parent progeny test of 12 plus tree of 3-year-old Mytilaria laosensis in Baisha Forest Farm of Shanghang County were investigated.Parameters such as correlation coefficient,heritability and genetic gain were estimated.Result shows that the grouth of single parent progeny of superior tree is optimal than of the parent tree of mixed species;the average tree height,DBH and individual volume increase by 4.6 m,5.4 cm and 0.006 9 m3 in the two excellent families;the genetic gain is 5.3%,4.1% and 12.1%,respectively.Excellent single-plant selection was conducted in excellent families.The average tree height,DBH individual volume of 12 excellent singleplant is 5.6 m,6.8 cm and 0.013 32 m3,respectively;genetic gains is 29.8%,32% 59.3%,respectively.It shows that the combination of plus tree and excellent single-plant can obtain double-level genetic gain.
