‘Niagara Steck’ and ‘Niagara Variegada’ are two grapevine varieties that arose spontaneously as somatic mutants of ‘Niagara Rosada’. Berries characterize ‘Niagara Steck’ at young stages exhibiting a remarkable brown reticulated structure on the epidermis which develops into a brown-bronze russet-like structure as the berries ripe. The mature berries have strongly acidic flesh. ‘Niagara Variegada’ shows notable variegation in leaves and berries. Meiotic studies were carried out to ascertain if the mutant phenotypes could be related to any change in chromosome number, structure or other irregularity. Floral buds of both varieties at different developmental stages were collected and fixed for cytological analyses. Chromosome counts at diakinesis/metaphase I showed n=19 bivalents for both varieties. Univalent, trivalent, tetravalent chromosomes or chain configuration were not recorded ruling out the possibility of any alteration in the chromosome number or structure in both mutant varieties. However, low percentages of meiotic irregularities were recorded such as chromosome stickiness, laggards, non-oriented chromosomes, precocious chromosome segregation, tetrads with one microcyte, microspore fusion, and tetrad degeneration. The total percentage of abnormalities was higher in ‘Niagara Variegada’ (19.68%) than in ‘Niagara Steck’ (14.40%) which may have contributed to a lower percentage of pollen fertility (79.80%) when compared to ‘Steck’ (90.74%). The aforementioned varieties can be propagated by hardwood cuttings and constitute an interesting option for ornamentation of home backyards, patios, and gardens with the advantage that ‘Niagara Variegada’ bearing sweet edible berries.
