Partial map of Coffea arabica L. and recovery of the recurrent parent in backcross progenies

A partial map of Coffea arabica L. was constructed based on a backcross population and RAPD markers.From a total of 178 markers evaluated, only 134 that segregated 1:1 (P>0.05) were used to develop the map. Seventeenmarkers were not linked, while 117 formed 11 linkage groups, covering a genome di...
