  Microsatellite markers were used to investigate the genetic basis of cowpea yellow mosaic virus (CYMV) resistance in 40 cowpea lines. A total of 60 simple sequence repeat (SSR) primers were used to screen polymorphism between stable resistance (GC-3) and susceptible (Chrodi) genotypes of cowpea. Among these, only 4 primers were polymorphic and these 4 SSR primer pairs were used to detect CYMV resistant genes among 40 cowpea genotypes. The polymorphism information content (PIC) of these SSR markers ranged from 0.30 to 0.72. A dendrogram of these genotypes based on microsatellite polymorphisms generally agreed with the CYMV resistant phenotype of these lines. All the genotypes could be divided into two major groups, separated at 45% similarity. The resistant group comprised of 18 cowpea lines with 77 to 100% similarity, in which 10 genotypes shared 100% similarity. Also, the two resista.. View More»
