“…Cuf. are the four wild Linum species in Ethiopia (Edwards 1991). Even these more distant germplasm pools may be useful to increase variation by crossing with linseed, since several Linum species can produce viable and fertile hybrids (Seetharam 1972;Friedt 1989).…”

Molecular characterization of germplasm is important for sustainable exploitation of crops. DNA diversity was measured using inter-retrotransposon-amplified-polymorphism and inter-simple-sequence-repeat markers in 203 Ethiopian landraces and reference varieties of linseed (flax, Linum usitatissimum) and wild Linum species. Molecular diversity was high (PIC, 0.16; GD, 0.19) compared to other reports from the species. Genotyping separated reference from landrace accessions, and clustered landrace accessions from different altitudes and geographical regions. Collections showed evidence for recent introduction of varieties in some regions. The phylogeny supported L. bienne Mill. as the progenitor of domesticated L. usitatissimum. Markers developed here will be useful for genetic mapping and selection of breeding lines. The results show the range of characters that can be exploited in breeding lines appropriate for smallholder and commercial farmers in Ethiopia, producing a sustainable, secure, highvalue crop meeting agricultural, economic and cultural needs.

“…Besides this, there is no systematic study on selection, classification, diversity, production and use of D. bulbifera in the country. Evaluation and conservation of germplasm are viewed to be the most feasible solution to the problems, efficient utilization and breeding so as to reduce further genetic erosion (Edwards, 1991). In order to get promising germplasm to end users, a system which enables farmers' selection and classification of the accessions is crucial.…”

“…Folk identification and classification to a certain extent also helps in estimating genotypic diversity. Folk taxonomists depend on a wide range of information including not only characteristics of the taxa in question, but also location in certain habitats and seasonal periods (Boster, 1985;Edwards, 1991). The folk system relies chiefly on the use classes of tubers such as edibility, taste, flesh color, size, and direction of growth, fiber content, cooking properties and occasionally tuber and bulbils number.…”

“…Nevertheless, this germplasm is being lost because of replace the crop by cereals (high value), drought and human interference such as deforestation. Therefore, there is need to characterize, conserve and maintain the germpalsm to serve as a source of desired genotypes for further breeding pur-colocasia esculenta/ accessions in ethiopia poses and to reduce further genetic erosion [4]. In Ethiopia, some taro germplasm collection and conservation works have been started by agricultural research centers.…”

Abstract:One hundred accessions of taro (Colocasia esculenta) were tested at Jimma Agricultural Research Center during the 2011 growing season by using 10 x10 simple lattice design with two replications. The objectives of the study were to assess the nature and extent of diversity with in collected accessions based on key morphological descriptors and evaluate the accessions based on yield and yield related traits. Data on 17 qualitative and 13 quantitative traits were measured. Both sets of data collected were subjected to multivariate analysis using principal component (PCA), cluster analysis and of analysis of variance to determine the variability among accessions. The results of PCA based on qualitative traits reveled that characters have large contribution to the variability. The two-dimensional plot of the first two PCs showed a separation between accessions of big sized. Cluster analysis based on qualitative characters indicated the formation of seven clusters and existence of variability, based on their foliar and subterranean traits. Shannon-Weaver diversity index (H=0.27) showed that low levels of diversity existed among 100 C. esculenta based on the frequency of phenotypic characters that were considered. The analysis of variance for quantitative traits showed that number of active leaves/plant, petiole length and maximum horizontal distance highly significance differences exists for majority of characters studied and also path coefficient analysis at genotypic level showed that there are a number of characters exerting a maximum direct positive effect on fresh tuber yield suggesting that these characters are good contribution to the fresh root yield in taro. Overall, this study indicated that taro accessions collected from south and southwestern Ethiopia have an enormous wealth of traits variation for qualitative and quantitative characters, indicating huge potential for its genetic improvements through selection and hybridization. Therefore, selections based on these characters are efficient to maximize the fresh root yield and the genetic improvement of the crop.
