dc.description.abstractEnset (Ensete ventricosum (Welw.) Cheesman), which feeds around 20 million Ethiopian people, is a unique crop; with all parts of the plant are utilizable. It is, arguably, less researched crop and the mode of production remained conventional. Understanding the extent of genetic diversity in the crop, especially making use of genotyping data, is a very important first step in the genetic improvement of the crop. Twelve polymorphic enset SSR markers were used to assess the genetic diversity and population structure of 79 cultivated landraces and four wild enset individuals collected from different enset growing locations of Ethiopia. The polymorphic information content of markers ranged from 0.62 to 0.77 with a mean value of 0.69. A total of 77 alleles were identified, and the average observed heterozygosity varied from 0.51 to 0.67. A mean gene diversity of 0.59 was recorded ranging from 0.55 to 0.62. The AMOVA revealed that within population allelic variations contributed more to the genetic diversity than among population variations. Discriminant Analysis of Principal Components and population structure analysis grouped the 83 enset germplasms into three major clusters, where the wild individuals clustered distinctly. Outcomes of this research provide valuable information for enset conservation and breeding strategies especially for development of resistance for bacterial wilt and nematode attacks.
