Abstract

Genetic Diversity in Cassava (Manihot Esculenta (Cranz)) and its Implication in its Improvement

Neim Semman Abadura*

Cassava is a widely produced root crop serving as food security in developing countries. There were number of efforts so far done on morphological, compositional and molecular variability-based study. However, little review and organized document of such works based on the whole marker information in one. So, this paper presents the results of these research. Through this review, variability of different genotypes across the world were recognized from different studies even though range of variability varied from report to report based on number of accessions and sources of studied materials used. Accordingly, morphological marker-based analysis classified studied genotypes into different groups where their first two to three PCA showed high percentage of variation. The biochemical markerbased analysis also showed significant differences. This genetic variability of the crop enables to grow and perform in wider agro-ecologies unlike other crops. Also, it has an opportunity of gaining heterosis under breeding and trait improvement through both conventional and modern breeding methods. The molecular marker-based diversity also revealed significant variation among assessed cassava genotypes. So, systematic germplasm collection and strategic conservation is recommended.
