Abstract:

【Objective】 The provenances trial was to select high productivity, good stability of Fraxinus mandshurica provenances for Dailing, Lushuihe and Maoershan where the trials were established and adjacent areas. 【Method】20 provenances of F. mandshurica were used to study the phenotypic variation in tree height (H), diameter at breast height (DBH) and volume (V) at the age of 14 by analysis of variance and multiple comparisons for single site and three sites. Stability of performance was assessed with regression coefficients (bi) of the joint regression analysis of Eberhart & Russell. Finally, geographic variation was analyzed with trend surface. 【Result】 1) The results showed that there were statistically significant (P<0.01) differences in H, DBH, and V among different sites and provenances, and also significant in site× provenance interaction. At Lushuihe site, the top provenances were Hailin (7.55 m), Dailing (7.34 m) and Lushuihe(7.05 m) in terms of H, Hailin (6.13 cm) and Lushuihe (5.47 cm) in terms of DBH, and Hailin (14 909 cm3) in terms of V. In terms of H(7.62 m), DBH(6.79 cm) and V(16 747 cm3) together, Wuchang was selected at Maoershan site. Xinglong (5.67 m), Linjiang (5.65 m) and Dongfanghong (5.61 m) were selected in terms of H, Linjiang selected in terms of DBH(5.07 cm) and V(7 984 cm3) at Dailing site. For all three sites, provenance Wuchang was selected in terms of H(6.35 m), Linjiang in terms of DBH(5.35 cm), Hailin(10 546 cm3), Wuchang(9 857 cm3) and Linjiang(9 818 cm3) in terms of V. 2) The stability analysis showed the provenances of Youhao, Linjiang, Xifeng, Dailing, Wangqing and Tangwanghe had an average stability, the provenances of Xinglong, Lushuihe, Hengren, Hailin, Wandianzi, Suiling and Sanchazi had a high stability, the provenances of Huinan, Maoershan, Fangzheng, Dongfanghong, Zhanhe, Huanan and Wuchang had a low stability. 3) Geographic variation analysis showed that the effect of latitude was greater than that of longitude on the growth of F. mandshurica, the volume of the provenances along the direction from northwest to southeast was larger than the others. 【Conclusion】It was found that the selection at 14-year-old was closer to the selection at 6-year-old than to the selection at 2-year-old, indicating that provenances selection was not stable if it was made too early. The results provide a useful basis for germplasm management and genetic improvement of F. mandshurica.
