A solitary mosaic specimen presented over 70% of its chromosome plates at the pentaploid
(5n) level (Figure 5).
Among the Chinese accessions, the pentaploid

Diplosporous and aposporous apomixis in a pentaploid

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.

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
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).
