From: Targeted generation of polyploids in Hydrangea macrophylla through cross-based breeding
Phenotype, 2C DNA content and estimated chromosome numbers of progenies from crosses between diploids (top) and interploid crosses between diploid and triploid plants (bottom). The cross ‘Dark Angel’ x ‘Sheila’ produced diploid offspring (a), whereas the reciprocal cross ‘Sheila’ x ‘Dark Angel’ resulted in diploid and triploid progenies (b), all with normal development. The cross ‘Blaumeise’ x ‘Sweet Dreams’ (c) and the reciprocal cross ‘Sweet Dreams’ x ‘Blaumeise’ (d) resulted in aneuploid offspring between diploid and tetraploid level with abnormal phenotypes
