Let's also get rid of the idea that cultivars are unique genotypes.
While some cultivars are unique genotypes (i.e., asexually progated cultivars,
hybrids, and self-pollinated cultivars derived from a single, homozygous
seed), the rest would not be. This includes cultivars of cross-pollinated,
seed derived crops, and cultivars consisting of blends or mixtures of
self-pollinated crops (including early-generation composites).
A simple definition for a cultivar is from Fehr's Principles of Cultivar
Development. It states that
"Variety: Subdivision of species for taxonomic classification. Used
interchangeably genetically with the term cultivar to denote a group of
individuals that are distinct genetically from other groups of individuals in
Thus, the individuals in a cultivar are expected to have a distinguishing
genetic characteristic in common, but other than that, need not be of the same
Finally, there is nothing to say that a cultivar must be the result of a
breeding program. Land races, ecotypes (whatever may be the difference
between these two terms), and even individual genotypes collected from the
wild have at various times been released as cultivars.
