Abstract:
The natural distributing populations of the indigenous timber species Cordia afiicana that grew in and around the area of Mizan Teferi in Ethiopia were investigated. Bulk seed samples were selected from ten phenotypically superior trees in different natural populations. They were evaluated through the performance of their half-sibs and especially examined for variability in seed morphometrics, seed germination, and seedling growth at nursery stage. The results showed that there was no correlativity between germination percentage and seedling height, but there were significant differences among provenances in all studied attributes. The elite trees for establishing seed orchard were screened out in pilot study. The observed variability of this species would have applications in could be used to geneticresources conservation and tree improvement. The germplasm supplied from nurseries and germplasm availability enhance the protection and utilization of natural regeneration,on farm.
