One particular system of crossing, then repeatedly backcrossing the hybrid with
its original parent, produces what are known as alloplasmic plants. In a straight
cross between two plants, the parents' nuclei fuse but the cytoplasm is inherited ...

Annual Plant Reviews, Flowering and its Manipulation
The alloplasmic situation is thought to reflect impaired co-operation between the
mitochondrial and nuclear genomes. This impairment occurs because, unlike the
nuclear and mitochondrial genomes of a given species, these genomes did not ...

Thus, a modified cultivar known as an alloplasmic line is derived. In the tetraploid
Triticum durum (2n = 4x = 28) and the hexaploids T. aestivum (2n = 6x = 42),
alloplasmic lines expressing CMS are derived from related genera (Kihara, 1951;
