“…If this occurs with appreciable frequency, the difficulties inherent in treatment with colchicine would be circumvented. If seeds are formed as a result of failure of the first or second division, useful variants in chromosome number and structure would be anticipated due to atypical meiosis in haploids (Kihara and Nishiyama 1937, Sears 1939, Endrizzi and Morgan 1955, Reddi 1971. Line G168A, derived by colchicine treatment of a haploid of the variety Goliath, produces haploids with a higher than average frequency (Campos and Morgan 1960 number of 12 chromosomes.…”
