Within ploidy levels, the range of GSCs and the average GSC of tetraploids were smaller than those of the hexaploids and pentaploids, showing that the Chinese tetraploid Cynodon contained much wider genetic diversity compared with the pentaploid and hexaploid cytotypes.

3) showed that hexaploid and pentaploid accessions formed clusters or subclusters in mixture with or close to tetraploid accessions that originated in the same geographic region as the pentaploids and hexaploids.

1] pentaploids of both families grown to reproductive maturity were large robust plants, but to have enough material to carry out our hybridization program, we had to graft 10 scions from the first two G.

2] plants, coming from the backcross of the pentaploids to Stam F, were phenotypically similar to G.

Because PI 409704 is a pentaploid (2n = 5x = 45), common buffelgrass was used as an internal standard for all PI 409704 seedlings.

These data are the first evidence of pentaploids among buffalograss, in data from clones (Table 1) as well as progeny in seed populations (Table 3), most notably the cultivar 315.

These data show that pentaploids of buffalograss have been produced, and most likely have been produced in wild populations.

As with pentaploids, hexaploids are also the result of 2n + n matings and are considered [B.

The genus consists of diploid (2n = 2x = 36), triploid (2n = 3x = 54), tetraploid (2n = 4x = 72), pentaploid (2n = 5x = 90), and hexaploid (2n = 6x = 108) cytotypes.
