In long cultivated plant species - such as wheat, barley, bean, soya, tomato - during their microevolution from wild to modern cultivated species, the genome size has increased by 200 - 300 %. Presumably the newly acquired DNA of the cultivated species consists both of no coding, repetitive DNA and of new copies of the polygenesis that control the culture-characters. It seems, that in cultivated plants the genetic bases of the gigas-character and of the allometric-growth of the plant organs useful for man, are the amplified polygenesis, which control these characters.
