The Dilatata group of Paspalum is a polyploid complex native to the grasslands of temperate
South America. A pentaploid apomictic biotype of P. dilatatum is a widely recognized forage
grass; however, the complex includes apomictic tetra-and hexaploids along with sexual
allotetraploids (P. urvillei, P. dasypleurum, P. dilatatum ssp. flavescens, and biotypes
Virasoro and Vacaria of P. dilatatum) which are suspected to be hybrids between different
combinations of biotypes. Fifteen primer pairs for nuclear microsatellite loci were developed …
