Q.Plants having similar genotypes produced by plant breeding are called :

A group of genetically identical/similar plants produced by breeding (typically via vegetative propagation) is called a clone.

Working

In plant breeding, a clone refers to a population of plants that are genetically identical (or very nearly so) to one another and to the original 'mother' plant, because they have all been produced through asexual/vegetative propagation (such as cuttings, grafting, layering, or micropropagation) rather than through seed (sexual reproduction), which would introduce genetic recombination. Since asexual propagation does not involve fertilisation, every plant in the clone carries the same genotype, and hence the same desirable traits, as the parent -- making cloning a valuable technique for multiplying elite, high-performing varieties unchanged. Checking the distractors: Autopolyploid refers to an organism carrying more than two chromosome sets, all derived from the same species (a chromosomal condition, not a description of similar plants …
