Hugo de Vries had experimented with the cultivation and breeding plants, such as asters, mums and violets. Based on these experiments he concluded that the character of a plant, the genetic material was built up of certain units. Every feature (for instance the colour of a leaf) was in other words corresponding with a specific material carrier or transfer. These would later be referred to as genes. Hugo de Vries wrote the two volumes of his book in 1901 and 1903. The book ‘Die Mutationstheorie’, in which he described an evolution theory, implied that new species could evolve in leaps instead of very small steps as Darwin described.
The book 'Het veredelen van Kultuurplanten' was published in English a year after his journey to California and was later translated into Dutch by P.G. Buekers and was published a year later.
