Resumen

Karyotypes from two morphotypes in 30 populations of Muhlenbergia rigida (Kunth) Trin. from locations in six states in north central Mexico were analyzed. The basic ploidy (x = 10), tetraploidy (n = 40) and disploidy (n=44) reported previously for the species are confirmed, and triploidy (n = 30) is reported for the first time in 13 of the 30 populations studied. Analysis of karyotypes reveal a correlation among cytotypes and morphotypes of M. rigida. Tnploid cytotypes correspond to the morphotype having open inflorescences whereas tetraploid and disploid plants correspond to the morphotype with dense inflorescences.
