Genetic variation and population structure of maize inbred lines adapted to the midaltitude sub-humid maize agro-ecology of Ethiopia using single nucleotide polymorphic (SNP) marke... by Ertiro, B.T., Semagn, K., Das, B., Olsen, M., Labuschagne, Maryke T., Worku, M., Wegary, D., Azmach, G., Ogugo, V., Keno, T., Abebe, B., Chibsa, T., Menkir, A.

“…The genetic distance and relative kinship analysis clearly indicated the uniqueness of most of the inbred lines in the maize germplasm available for breeders in the mid-altitude maize breeding program of Ethiopia. Results from the present study facilitate the maize breeding work in Ethiopia and germplasm exchange among breeding programs in Africa. …”
