Some early observations on transgeneration of acquired traits

Plant	Trait	Causative factor	Transmission	Year	Ref.
Linum usitatissimum (flax)	Blanching/weight	Nutrient	Over 6 generations	1962	4
Nicotiana rustica (tobacco)	Weight/flowering	Nutrient	At least 2 generations	1965	5
Antirrhinum majus (Snapdragon)	Variegation	Crossing	At least 2 generations	1987	25
Oryza sativa (rice)	Dwarfism	5-azacytidine	At least 3 generations	1990	6
Triticale	Height/ripeness	5-azacytidine	At least 2 generations	1990	7
Linum usitatissimum (flax)	Early flowering	5-azacytidine	At least 3 generations	1994	8

Recent data obtained from model plants such as Arabidopsis are not listed due to abnormal properties derived from mutants and transgenics. Such information will be available through refs. ², ⁹, ²³ and ²⁴.
