Abstract: The response of 13 alder(Alnus cremastogyne) provenances was evaluated for height at 5 test locations. The genetic stability and adaptability of provenances have been evaluated by using Eberhart's trait regression parameters(b_i and S_di², Wricke's ecovalue parameter(W_i), the D_i parameter of additive main effects and multiplicative interaction analysis(AMMI). The estimates of AMMI are greatly concordant with the estimates of ecovalue. The methods of AMMI model is comparatively scientific and efficient. It proved that there was a highly significant difference among provenance in height. The stability of provenances including Shawan, Luding, Yaan and Huaikou, Jingtang in height was the highest. The stability of provenances including Changle, Jingtang, Muchuan in height was also the lowest.
