摘要

Acacia raddiana (L.) Willd. is an African leguminous multipurpose tree species belonging to subfamily Mimosoideae, subgenus Acacia, highly valued for pods, leaves and gum production. This study estimated the genetic diversity within and among Moroccans populations of the species in the Agdz, N'Koub, Tazarine, Mceissi, Tata, Tissint, Foum Zguid, Gluemim, Msceid and Assa provenances based on 9 quantitative traits which included; Pod Length (LP) (cm), Pod Width (WP) (mm), Pod Weight (WtP) (g), Seed Weight per Pod (WtS P~(-1)) (g), Empty Pod Weight (WtEpP) (g), Seed Number per Pod (SN P~(-1)), Infected Seed Number per Pod (InSN P~(-1)) and 100-seed weight (100-Wt) (g) and shapes of pods throughout two seasons. In the both seasons provenances N'Koub, Tazarine and Tissint present the best means for the majority of traits studied, indicating geographical structuring of the genetic variability but it remained much reduced. Analysis of traits in various forms has shown that purely morphological criteria areinadequate for the selection of the Acacia raddiana trees which had a range of quantitative characters. The various traits are not regularly correlated with pods quality; they appear strictly in a variety of combinations and relations with environmentalconditions. In view of this, any attempt for selection based on morpho-metrics traits of the polymorphic species must fail.
