A solitary mosaic specimen presented over 70% of its chromosome plates at the
pentaploid (5n) level (Figure 5).
Among the Chinese accessions, the
pentaploid genotypes separated from tetraploid and hexaploid accessions (Fig.
juzepczukii (triploid), and S', curtilobum (
pentaploid).

Diplosporous and aposporous apomixis in a
pentaploid race of Paspalum minus.
Thousands of seeds were obtained from selfing the 196
pentaploid hybrid plants ([A.sup.r][A.sup.n][B.sup.c][C.sup.c][C.sup.n], 2n = 46) that were derived from crosses between the synthesized hexaploid of [A.sup.r][A.sup.r][B.sup.c][B.sup.c][C.sup.c][C.sup.c] (2n = 54) and double-low cultivars (low erucic acid and low glucosinolates) of B.

pentaploids. Heredity 68: 193-200.
Regeneration of anther-derived plants from
pentaploid hybrids of Festuca arundinacea x Lolium multiflorum.
T and t chromosomes are rare, and where they do appear [as in Allium roseum, x = 8 (7 M + 1 t)] at diploid, tetraploid, and
pentaploid levels, it is likely that the t's are the result of centric shift in sm chromosomes of similar length.
Chromosome analysis of the Dinkel genome in the offspring of a
pentaploid wheat hybrid.
In an ideal situation, the
pentaploid hybrids can be expected to possess 7 pairs of D genome chromosomes, and a haploid set of A (7 chromosomes), B (7 chromosomes), and C (7 chromosomes) genomes with a hybrid genome of 2n = 5x = 35, DDCAB or BADDC (depending on whether jointed goatgrass or bread wheat is the female parent).
