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 *** 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 *** the analysis on the feasibility and the reliabili-ty of the provenance early selection,the best provenances which lie in the southeast of theXiaoxingan *** regarded as the best and suitable for a large afforestation areas of *** in the north of Xingan Mt.,the local or the northwest provenances of theXiaoxingan *** be *** genetic gain was calculated on the basis of the provenanceheritability and the utilization of the best provenance were evaluated in this paper.
