Mating system parameters in Stylosanthes guianensis (Aubl.) Sw. based on RAPD markers
This study investigated the mating systems in Stylosanthes guianensis, an important tropical forage legume. Twelve progenies were analyzed with 21 polymorphic random amplified polymorphic DNA (RAPD) loci. The mating parameters estimated using the mixed mating model showed that this population practices a mixture of selfing (61.4%) and out-crossing (38.6%) for reproduction. The results also indicated that the fraction of multilocus out-crossing of about 8.2% occurred among related individuals. Low values were obtained for correlation of paternity (0.212 ± 0.046) and correlation of selfing among families (0.102 ± 0.001). These results have important implications to establish strategies of maintenance of germplasm and genetic breeding.
