Genetic relationships between Dioscorea alata L. cultivars

Isozyme variation was studied to determine genetic relationships among 269 cultivars of Dioscorea alata originating from the South Pacific, Asia, Africa and the Caribbean. Four polymorphic enzyme systems (MDH, PGI, SkDH, 6PGD) revealed 66 isozyme phenotypes, or zymotypes, each uniquely characterized by the presence or absence of 27 electromorphs. Identical… CONTINUE READING
