With the aim of selecting suitable families for Fujian province, the growth traits of families of disease resistance Pinus elliottii and P.taeda, which were introduced from USA and planted in gene bank, were evaluated. The results showed that P.elliottii and P.taeda grew well in Fujian province, China. The average value of tree height was 5.95 m, that of DBH was 11.1 cm, and the crown was 3.30 m, when the P.elliottii was 8 years old. The same average values of P.taeda were 5.97 m, 10.7 cm and 3.66 m respectively. There were genetic variations among families on tree height, DBH and crown. These variations were controlled by genetic factors with moderate intensity. The five P.elliottii families such as M39×8 were selected, their average values of tree height, DBH and crown were 8.69 m, 13.9 cm and 4.48 m respectively, these values were better 46.05 %, 25.23 % and 35.76 % better than those of selection group. The genetic gain of tree height was 1663 %, that of DBH was 11.90 % and crown’s was 17.22 %. The five P.taeda families such as (5-142)×(5-148) were selected and the selection effects of P.taeda were similar to P.elliottii, but those were slightly better than P.elliottii. The selection effects of these two species were effective, and selected families could be widely used for artificial plantations in Fujian province.
