Variation in Seed Characteristics of Acacia seyal Delile var.seyal From Two Provenances in Sudan

Abstract

Variability studies are necessary to the begging of tree improvement program. The objective of this study is to evaluate the magnitude of variation in seed characteristic traits and estimate the genetic parameters among two provenances of the Acacia seyal var.seyal. Significant differences were found among the two provenances for all parameters studied. The two provenances of Acacia seyal var.seyal showed that seed weight was influenced by environmental variance. For Damazin provenance the partitioning of the total variance revealed that seed width was recorded at genotypic variance, while for Heritability value was found high for seed weight (85.71%). The results showed that seed weight and seed germination are under genetic control, they can be used as parameters for selection and improvement of this species.
