Abstract

 A field experiments was conducted in greenhouse to determinate the genetic diversity among 7 genotypes from maize(4 inbreds and 3hybrids) by using molecular markers with Random Amplified polymorphic DNA(RAPD),that shown high level of polymorphism among genotypes of maize ,where the percentage of polymorphism ranged from(66%) and (83.33%) the highest number of polymorphism band (16) and size fragment ranged between (3800 bp) with the primer ( Bnlg 1185 ) and the lowest 180 with the primer( Bnlg 1464).The genetic distance value ranged between (0.3451) and (0.6534) ,where the lowest genic distance between (k1 and k2),while the highest genetic distance between(k4) and (k3xk4).In this study RAPD markers were shown to be powerful to detect genetic diversity and provided us high polymorphism values within genotypes of maize ,also we can conclude for useful those primers for genetic studies in plant breeding programs for developing synthetic cultivars or improved inbreds of maize.
