RAPD based differentiation among Catimor coffee lines derived from hybrid HW 26-5
In a previous report on Coffea arabica, a Catuai Vermelho line and 23 Catimor lines (generation F6 and F7 derived from CIFC HW 26-5 hybrid) were evaluated by means of morphological descriptors. These were not efficient in grouping the lines according to their genealogic data, except when descriptors with high heritability (major who 80 percent) were considered. The same lines are now evaluated with random amplified polymorphic DNA (RAPD) markers. Genetic distances were estimated based on 14 polymorphic loci. Grouping analysis based on the genetic distances obtained with RAPD markers was in accordance with the genealogic data of these lines, showing that these markers were efficient in differentiating among descendants of Catimor lines derived from CIFC HW 26-5 hybrid.
