OPEN POLLINATION PROGENY TESTING AND MULTIPLE-TRAITS SELECTION ON CHINESE FIR

Open pollination progeny testing of 54 families of 8-year-old Chinese Fir was conducted.The main economic traits including growth development and trunk-shape were measured in order to find out: (1) the differences between different traits of Chinese Fir families;(2) genetic variation of quantitative traits among the families;(3)and at last,by using of Index Selection Method,16 fast-growing families with higher qualities were assessed.The genetic gain in the selective index values reached 20.17%.The results also show that Index Selection Method is very effective.
