Genetic diversity and population structure in Ethiopian Urochloa brizantha genotypes uncovered using inter simple sequence repeat (ISSR) markers.

ABSTRACT: Urochloa brizantha is a tropical C4 grass belonging to the Urochloa genus. Despite its immense potential as animal feed and its contribution to livestock production in sub-Saharan African countries, particularly Ethiopia, its utilization remains limited due to an inadequate supply of Urochloa cultivars and an insufficient genetic characterization of currently available genotypes. Hence, this study was conducted to assess the genetic diversity and population structure of 66 U. brizantha genotypes from the Ethiopian collection by leveraging six polymorphic inter-simple sequence repeat (ISSR) markers. These markers generated a total of 80 scoring bands, with 79 of which were polymorphic, and an average of 13.33 bands per primer. The polymorphism information content (PIC) ranged from 0.31 to 0
