Because bread wheat is a polyploid, many types of aneuploids (plants that do not have the normal chromosome number or some multiple of it) are viable and fertile. Sears (1954) produced the complete sets of 21 monosomics (20″ + 1′, lacking one member of a chromosome pair), 21 nullisomics (20″, lacking both members of one pair), 21 trisomics (20″+1‴, carrying three chromosomes of one type) and 21 tetrasomics (20″ 4-1‵, carrying four chromosomes of one type).
