Abstract

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 controls these characters.
