| 摘 要： | In this paper,it is studied that the growth characters of the progeny of 16provenance of larix gmelinii within the all 13 experimental sites by means of the analysis of va-riance,provenance stability,productivity index,rank correlation,synthetic index selection andPCA.The provenances were divided into three patterns:The first type have low and steady prod-uctivity;The second type have high but unsteady productivity;The third type is between theproductivity of the first and second type.Through the analysis on the feasibility and the reliabili-ty of the provenance early selection,the best provenances which lie in the southeast of theXiaoxingan Mt.are regarded as the best and suitable for a large afforestation areas of Larixgmelinii.Then in the north of Xingan Mt.,the local or the northwest provenances of theXiaoxingan Mt.should be used.The genetic gain was calculated on the basis of the provenanceheritability and the utilization of the best provenance were evaluated in this paper.

| Abstract: | In this papcr,it is studied that the growth characters of the progeny of 16 provenance of larix gmelinii within the all 13 experimental sites by means of the analysis of variance, provenance stability, productivity index, rank correlation, synthetic index selection and PCA.The provenances were divided into three patterns: The first type have low and steady productivity; The second type have high but unsteady productivity; The third type is between the productivity of the first and second type. Through the analysis on the feasibility and the reliability of the provenance early selection, the best provenances which He in the southeast of the Xiaoxingan Mt. are regarded as the best and suitable for a large afforestation areas of Larix gmelinii. Then in the north of Xingan Mt., the local or the northwest provenances of the
Xiaoxingan Mt. should be used. The genetic gain was calculated on the basis of the provenance heritability and the utilization of the best provenance were evaluated in this paper. |
